The equation of a line that goes through the point (-8, 7) and is parallel to the line (24 -16).

The equation of a line that goes through the point (-8, 7) and is parallel to the line -9x+8and 24.

Two lines have equal slopes if they are parallel to one another. In other words, both equations have an identical ratio of the x and y coefficients.

For any real value of k, the equation for the line perpendicular to the line axe + by + c = 0 is given by axe + by + k = 0.

Thus, a line parallel to the line 9x + 8y - k = 0 has the equation 9x + 8y + k = 0.

We know that this line intersects at (-8, 7), thus 9(- 8) + 8(7) + k = 0 k= -16 Rightarrow

We obtain 9x + 8y - 16 = 0 by substituting k = - 16 in the line equation.

The solution is 0 for 9x + 8y - 16.

To estimate the number of classmates who do not belong to a major political party, we can use the proportion of students in the sample who do not belong to a major political party as a basis.

Out of the 40 students surveyed, 10 do not belong to a major political party, so the proportion is 10/40 = 0.25.

We can then multiply this proportion by the total number of classmates to estimate the number who do not belong to a major political party:

0.25 * 250 classmates = 62.5 classmates

So about 62 or 63 of the 250 classmates are estimated to not belong to a major political party.

How to solve equation?

To solve an equation is to identify its solutions, which are the values that satisfy the condition specified by the equation, which is typically two expressions linked by an equals sign. When trying to find a solution, one or more variables are labeled as unknowns.

Let the price of each blouse be x and the price of each skirt be y.

Debra's total cost: 4x + 3y = 68

Sue's total cost: 6x + 3y = 84

From the two equations above, we can solve for x and y:

6x + 3y = 84

4x - 3y = -68

2x = 16

x = 8

Substitute x = 8 back into the first equation:

4x + 3y = 68

4 * 8 + 3y = 68

32 + 3y = 68

3y = 36

y = 12

So, The each blouse costs $8 and each skirt costs $12.

Bobby around 131 minutes and Billy around 111 minutes

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

To solve the problem it is important to raise equations regarding what happens.

They tell us that Billy (Bi) and Bobby (Bo) can mow the lawn in 60 minutes. That is to say that what they prune in a minute is giving as follows:

1 / Bo + 1 / Bi = 1/60 (1)

They say Billy could mow the lawn only in 20 minutes less than it would take Bobby, therefore

1 / Bi = 1 / (Bo-20) (2)

Replacing (2) in (1) we have:

1 / Bo + 1 / (Bo-20) = 1/60

Resolving

(Bo - 20 + B0) / (Bo * (Bo-20) = 1/60

120 * Bo - 1200 = Bo ^ 2 - 20Bo

Rearranging:

Bo ^ 2 - 140Bo -1200 = 0

Now applying the general equation

Bo = 130.82 or Bo = 9.17, this last value cannot be because Billy took 20 minutes less and neither can he prune faster than the two together, therefore Bobby only takes around 131 minutes and Billy around 111 minutes

Answer:

Step-by-step explanation:

hi do you want me to answer this for you? Because I can.

Answer:

Step-by-step explanation: We can solve it by doing a cross multiplication, basically finding the X, which is how much he'd pay for 10 pounds:

24 ------- 4

x ---------- 10

You can read this as "if 24 dollars is 4 pounds, how many dollars is 10?"

Anyways, so we multiply on a "X" shape, like this:

4x = 24 x 10

The equation will look better if you multiply the X first.

CONTINUING:

4x = 24 x 10

4x = 240

x = 240/4

x = 60

Therefore, Jackson would pay 60 dollars for 10 pounds of apples.

We could also do this by finding out first how many pounds of apples you can get with 1 dollar, we would do the same thing as before, but now looking for the pounds, not the dollars:

24 ------- 4

1 --------- X

24x = 4

x= 4/24

x= 0,166

So you can buy 0,16 pounds of apples with 1 dollar, so if we want to find out how much we can buy with 24 dollars we multiply 0,166 by 24, which is 3,984, approximately 4 pounds.

But since working with small numbers is quite odd sometimes, I recommend you do this equation with the first method I mentioned.

[tex]\cfrac{7-2y}{6} \underset{\textit{greater than}}{~~ > ~~ }\cfrac{3y-7}{12}\implies 12(7-2y) > 6(3y-7) \\\\\\ 84-24y > 18y-42\implies 84 > 42y-42\implies 42 > 42y \\\\\\ \cfrac{42}{42} > y\implies {\Large \begin{array}{llll} 1 > y \end{array}}[/tex]

now, notice, on the last line we divided by 42, however 42 is a positive value, thus we didn't flip the inequality sign, recall that when dividing or multiplying by a negative value, the inequality sign flips, in this case it didn't.

Answer:

Option B. N=24; 1%-3.6; PV = ; PMT=-415; FV=0; P/Y=12; C/Y=12; PMT:END

Step-by-step explanation:

The TVM (Time Value of Money) Solver on a graphing calculator is used to calculate the present value (PV) of an investment. The input values for the solver include the number of periods (N), the interest rate (I%), the present value (PV), the payment (PMT), the future value (FV), the payment frequency per year (P/Y), and the compounding frequency per year (C/Y). In this case, the expression ($415)((1+0.003)24 - 1) is equivalent to the future value of an investment that receives a payment of $415 every period for 24 periods, with an interest rate of 0.3% per period. By plugging in N=24, I%=3.6, PV=0, PMT=-415, FV=0, P/Y=12, and C/Y=12 into the TVM Solver with PMT as the payment type, the same value for PV will be returned as the expression ($415)((1+0.003)24 - 1).

The equation that represents the given graph is: D. y = 2/5x - 3.

The slope-intercept form of the equation of a line is given by y = mx + b, where m is the slope of the line and b is the y-intercept.

To find the equation of a line that passes through two points (x1, y1) and (x2, y2), we can use the following steps:

So, for the line that passes through the points (0, -3) and (5, -1), the slope is (-1 - (-3)) / (5 - 0) = 2/5, and the y-intercept can be found by plugging in the slope and the point (0, -3) into the equation y = mx + b:

-3 = (2/5) * 0 + b

-3 = b

Therefore, the equation of the line that passes through (0, -3) and (5, -1) is:

Answer:

32ft

Step-by-step explanation:

Let's convert both the height of the person and the length of their shadow to feet so we can make a comparison.

1 foot = 12 inches

So the person's height in feet is:

5 feet + 6 inches / 12 inches/foot = 5.5 feet

The rule applied here is the concept of similar triangles. If the shadow of the person and the shadow of the flagpole are in the same proportion to their respective heights, then the two triangles formed by their heights and shadows are similar triangles. This means that the ratio of their heights to their shadow lengths is constant.

So, we can set the ratio of the person's height to their shadow length equal to the ratio of the flagpole's height to its shadow length and solve for the flagpole's height. This is done using the formula:

(person's height) / (person's shadow length) = (flagpole's height) / (flagpole's shadow length)

This is known as the proportionality rule, which states that two similar figures have the same ratios of corresponding sides.

Now, we have:

5.5/44 inches = x/16 feet

Cross multiplying, we get:

5.5 * 16 = x * 44

Solving for x:

x = 5.5 * 16 / 44

x = 32 feet

Therefore, the height of the flagpole is 32 feet.

The angles x and 148° are vertical angles and si the measure of the vertical angle x is equal to 148°.

Vertical angles also called vertically opposite angles are formed when two lines intersect each other, the opposite angles formed by these lines are vertically opposite angles and are equal to each other.

The angles 148° and x form vertical angles, so x = 148°

Therefore, since the angles x and 148° are vertical angles and and vertically opposite angles are equal, then the measure of the vertical angle x is equal to 148°.

The table represents a linear function because the rate of change is constant or all the points lie on a straight line.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables

From the given table it is noticed that the line passes through points (-1, -2), (0, 0), (1. 2), and (2, 4).

The slope of the line is

Slope = (2- 0)/1-0)

The slope of the line is. It means the value of y increased by 5 if the value of x increased by 2.

From the given points we can notice that the value of y increased by 5 if the value of x increased by 2. So, the function has the same slope for any two points.

Since the rate of change (slope) is the same for all points, therefore the table represents a linear function.

Therefore, If we plot these points on a coordinate plane and connect then we get a straight line. I mean it is a  linear function.
