Can you guys please help me with this question I think it’s A. but I’m not sure if it’s correct?!PLEASEEE

Step-by-step explanation:

Whatever value you put in for "y" will keep both of the equations equal

I’m pretty sure your right.

Solve the following simultaneous equations algebraically
xy = 6
y-x=1

Answers

Step-by-step explanation:

xy=6

x=6/y (1)

now,

XY=6

6/y-y=6

Answer:

x = -3, then y = -2
x = 2, then y = 3 both correct

Step by step explanation:

We can solve this system of equations algebraically by using substitution.

From the second equation, we can solve for y in terms of x:

y - x = 1

y = x + 1

Substituting y = x + 1 into the first equation, we get:

xy = 6

x(x + 1) = 6

Expanding the left side of the equation, we get:

x^2 + x = 6

Subtracting 6 from both sides, we get:

x^2 + x - 6 = 0

Factorizing the left side of the equation, we get:

(x + 3)(x - 2) = 0

Therefore, either x + 3 = 0 or x - 2 = 0. Solving for x, we get:

x = -3 or x = 2

Substituting these values of x into y = x + 1, we get:

if x = -3, then y = -2
if x = 2, then y = 3

So the solutions to the system of equations are (x, y) = (-3, -2) and (2, 3).

Answers

By using addition calculation, we determine that Angela will end up making 42 cards in total.

Angela made 23 cards for her friends, but she wants to make even more to share with others. To determine how many cards she will make in total, we need to add the number of cards she has already made with the number of cards she plans to make.

So, we add 23 (the number of cards she has made) and 19 (the number of cards she plans to make) so in total, she will make:

23 + 19 = 42

Therefore, Angela will make 42 cards in all.

By using simple arithmetic calculation of basic addition, we find that  Angela will make 42 cards in all.

Write a function y=ab^x that passes through (2,45) and (5,3072)

Answers

Therefore, the exponential function that passes through the points (2,45) and (5,3072) is: y = (45/16) ([tex]4^{x}[/tex]).

What is function?

In mathematics, a function is a rule that assigns to each element in a set called the domain, a unique element in another set called the range. In other words, a function is a mathematical object that takes an input and produces a specific output, according to a specific set of rules or operations.

by the question.

The general form of the exponential function is y = [tex]ab^{x}[/tex] where a and b are constants. To find the values of a and b that satisfy the given conditions, we can use the two points (2,45) and (5,3072) and solve for a and b.

First, we can write two equations based on the two points:

45 = a[tex]b^{2}[/tex] (1)

3072 = ab^5 (2)

We can then divide (2) by (1) to eliminate a:

3072/45 = (a[tex]b^{5}[/tex])/ (a[tex]b^{2}[/tex])

68 = [tex]b^{3}[/tex]

Solving for b, we get:

b = 4

Substituting this value of b into either (1) or (2) to solve for a, we get:

45 = a ([tex]4^{2}[/tex])

a = 45/16

if a data set is symmetrical, which statistical measure best represents the entire spread of the data set?

Answers

The best statistical measure to represent the entire spread of the data set when a data set is symmetrical is the standard deviation.

The standard deviation is a measure of how much the individual data points vary from the mean of the data set.

It is calculated by taking the square root of the variance.

It is the average of the squared differences of each data point from the mean.

In a symmetrical data set, the mean, median, and mode are all equal and located at the center of the data set.

This represents that the data points are evenly distributed around the center.

The standard deviation can provide a good measure of the spread of the data points from this center.

Other measures of spread representing the range or interquartile range, may not be as useful in a symmetrical data set .

As they are more affected by outliers and skewness in the data.

Therefore, the symmetrical data set in best way represented by statistical measure known as standard deviation.

a) Graph this system of inequalities, we can plot the lines x = 0, y = 0, x = 260, y = 320, and x + y = 380

b) The maximum profit of $5200 achieved.

Define the term selling profit?

Selling profit is the profit that a business makes on the sale of its products or services. It is the difference between the selling price and the cost of product.

a) Let x be the number of boards of mahogany sold and y be the number of boards of black walnut sold. Then, the constraints of the problem can be represented by the following system of inequalities:

x ≥ 0 (non-negative constraint)

y ≥ 0 (non-negative constraint)

x ≤ 260 (maximum number of mahogany boards available)

y ≤ 320 (maximum number of black walnut boards available)

x + y ≤ 380 (maximum number of boards that can be sold)

To graph this system of inequalities, we can plot the lines x = 0, y = 0, x = 260, y = 320, and x + y = 380 on a coordinate plane and shade the feasible region that satisfies all of the constraints. The feasible region is the area that is bounded by these lines and includes the origin (0, 0).

b) The profit function P(x, y) can be defined as follows:

P(x, y) = 20x + 6y

To maximize the profit, we need to find the values of x and y that satisfy all of the constraints and maximize the profit function P(x, y).

One way to do this is to use the corner-point method. We can evaluate the profit function at each of the corners of the feasible region and find the corner that gives the maximum profit.

The corners of the feasible region are (0, 0), (0, 320), (260, 0), and (120, 260).

P(0, 0) = 0

P(0, 320) = 6(320) = 1920

P(260, 0) = 20(260) = 5200

P(120, 260) = 20(120) + 6(260) = 4720

Therefore, the maximum profit of $5200 can be achieved by selling 260 boards of mahogany and 0 boards of black walnut.

In a study of the effects of marijuana during pregnancy, measurements on babies of mother who used marijuana during pregnany were compared to measurements on babies of mothers who did not. A 95% confidence interval for the difference in mean head circumference (nonuse minus use) was .61 to 1.19 cm. What can be said from this statement about a p-value for the hypothesis that the mean difference is zero?

Answers

The 95% confidence interval of .61 to 1.19 cm provides strong evidence that there is a difference in mean head circumference between babies of mothers who used marijuana during pregnancy and those who did not. Furthermore, the small p-value suggests that the mean difference is statistically significant, and is not likely to be zero.

The 95% confidence interval for the difference in mean head circumference between babies of mothers who used marijuana during pregnancy and those who did not is .61 to 1.19 cm. This implies that the true mean difference is likely to be between .61 and 1.19 cm. The p-value is a measure of how likely it is that the difference in means is zero, and can be used to assess the statistical significance of the difference in means.

Therefore, the p-value for the hypothesis that the mean difference is zero is very small and can be considered statistically significant.

The small p-value suggests that the mean difference is statistically significant, and is not likely to be zero.

A 95% confidence interval (CI) is a range of values that is expected to include the true population mean with a probability of 0.95. The CI for the difference in mean head circumference between non-users and users of marijuana during pregnancy is 0.61 to 1.19 cm.

This means that the sample mean difference (nonuse minus use) falls within this interval.

If the true population mean difference were zero, the sample mean difference would fall within the range of random sampling error, and the null hypothesis that there is no difference between the groups would be supported.

However, since the 95% CI does not include zero, we can conclude that the difference is statistically significant at the 0.05 level.

The system of equations x + y = 15 and 2x + 3y = 24

What is an equation?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

To substitute for the variable x in the equation x + y = 15, we can rearrange the equation to solve for x in terms of y:

x = 15 - y

Then we can substitute this expression for x in any other equation that involves x.

2(15 - y) + 3y = 24

Simplifying this equation gives:

30 - 2y + 3y = 24

y = -6

Then we can substitute this value back into our expression for x to get:

x = 15 - (-6) = 21

How to find the length of the median of a triangle?
Given that the centroid of a triangle is located 12 units from one of the vertices of a triangle. We need to find the length of the median of the triangle drawn from that same vertex.

Let ABC be a triangle.

Let AD be median of the triangle.

Let E be centroid of ΔABC

Length of the median of triangle = AD

AD = Length of AE + Length of ED

But,

AE = 12

ED = x

So,

AD = 12 + x

Since, centroid divides median in 2:1 ratio.

Then,

[tex]12 : x = 2 : 1\\12/x = 2/1\\\\12= 2x\\[/tex]

AB = [tex]\sqrt(261) cm[/tex]

For triangle CBD:

BC² = CD² + BD²

BC² = (8 cm)² + (15 cm)²

BC² = 289 cm²

BC = 17 cm

Now we can find the areas of the triangles:

Area of ABD =[tex]\frac{1}{2}[/tex] * AB * 6 cm

Area of ABD = [tex]\frac{1}{2}[/tex] * [tex]\sqrt(261) cm[/tex] * 6 cm

Area of ABD = 93.24 cm^2

Area of CBD = [tex]\frac{1}{2}[/tex] * BC * 8 cm

Area of CBD = [tex]\frac{1}{2}[/tex] * 17 cm * 8 cm

Area of CBD = 68 cm²

Finally, we can find the area of the quadrilateral by adding the areas of the triangles:

Area of ABCD = Area of ABD + Area of CBD

Area of ABCD = 93.24 cm² + 68 cm²

Area of ABCD = 161.24 cm²

Therefore, the area of the quadrilateral is 161.24 cm².

Answer: Quadratic polynomial.

Step-by-step explanation: Polynomials with 2 as the degree.

Idil drove 12 miles in 1/5 of an hour. On average how fast did she drive in miles per hour

Answers

If Idil drove 12 miles in 1/5an hour on average, then she drove at an average speed of 60 miles per hour.

To calculate the average speed of Idil's car in miles per hour, we need to divide the distance she drove (12 miles) by the time it took her to drive that distance (1/5 hour):

Average speed = distance ÷ time

Average speed = 12 miles ÷ (1/5) hour

To divide by a fraction, we can multiply by its reciprocal, so:

Average speed = 12 miles × 5/1 hour

Average speed = 60 miles per hour

Therefore, Idil drove at an average speed of 60 miles per hour.

During a fight-or-flight response, epinephrine is released into the bodys circulatory system and transported throughout the body. Some cells exhibit a response to the epinephrine while other cells do not.Which of the following justifies the claim that differences in components of cell signaling pathways explain the different responses to epinephrine?a. Cell signaling depends on the ability to detect a signal molecule. Not all cells have receptors for epinephrine. Only cells with such receptors are capable of responding.b. Cell signaling depends on the transduction of a received signal by the nervous system. Not all cells are close enough to a synapse to receive the signal and respond.c. Cell signaling depends on the signal being able to diffuse through the cell membrane. Epinephrine is incapable of diffusing through some plasma membranes because of the membranes phospholipid composition.d. Cell signaling requires reception, transduction, and response. All cells can receive epinephrine, all cells respond with a pathway, but only select cells have the proper coding in their DNA to respond. after the civil war, southern states still controlled setting voter qualifications which permitted the creation of laws severely limiting and excluding black americans from voting. srs of 25 seniors 17 respond "yes" confidence interval for true proportion of seniors which of the following conditions were not met?
