How to find the general equation of a Straight line?The formula for finding the general equation of a straight line is -
[y] = [m[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have Xochitl who went into a movie theatre and bought 6 bags of popcorn and 4 drinks, costing a total of $65, Alonso went into the same movie theatre and bought 9 bags of popcorn and 8 drinks, costing a total of $107.50.
Assume that the cost of one popcorn bag is $[x] and one drink is $[y].
Then we can write -
6x + 4y = 65
6x + 4y = 659x + 8y = 107.5
Plot the graph of both equations and the points of intersection would be the solution set. Refer to the graph below. We get x = $7.5 and y = $5.
Therefore, the cost of bag of popcorn is $7.5 and that of one drink is $5.

19. Gemma has three less than two-thirds the number of fish that Polly owns, Gemma has 15 fish. How many
does Polly own? Show all work necessary to justify your answer.
Answer:
Polly has 27 fish
Step-by-step explanation:
Polly's Fish= P
Gemma's Fish = G
so the equation to find either's amount of fish is G= [tex]\frac{2}{3}[/tex]P - 3
But since we know Gemmas amount of fish we can change G to be 15
15= 2/3 P- 3
then add 3 to both sides to get 2/3 P by itself
18= 2/3 P
and since P is being multiplied by 2/3 we have to divide both sides by 2/3 and if you want to divide by a fraction then you just multiply by the reciprocal ( flip the numerator and the denominator)
then you have
[tex]\frac{3}{2}[/tex] x [tex]\frac{18}{1}[/tex] = [tex]\frac{2}{3}[/tex] x [tex]\frac{3}{2}[/tex] P
which simplifies to
54/2 = 6/6 P
which further simplifies to
27 = 1P or 27=P
So P=27 which means polly has 27 fish
A landlord plans to take out a $12,000 loan to cover the cost of a new roof for a rental home. If the loan has a 5% annual interest rate compounded continuously and the landowner plans to pay off the loan in 21 months, what is the total amount owed? $34,291.81 $24,600.00 $13,328.53 $13,097.31
Using compound interest formula, the final payment for a principal of $12000 compounded continuously at rate of 5% is $13,097.31
What is Compound InterestCompound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods of a deposit or loan. It is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest.
The formula of compound interest is given as;
A = P(1 + r/n)^nt
A = compound interestP = principalr = rate n = number times t = timeSubstituting the values into the formula
A = Pe^rt
This formula is only for continuously compounded
A = 12000e^(0.05 * 1.75)
A = $13,097.31

Answer: It depends on how important you think sweet sixteen is, and how much money you have.
Step-by-step explanation:
First, if there is a lot of guests (I consider 32 a lot, but I don't know what you think), you need a lot of birthday cake, a lot of food and drinks, and entertainment. And that costs a lot of money.

On solving the provided question, we can say that A dilation is a transformation that yields a different-sized picture with the same general shape as the original.
what is dilation?A dilation in mathematics is a function f from a metric space M to itself that, for any point x, y in M, fulfills the identity d = rd. where r is a positive real integer and d is the separation between x and y. Such extensions are identical in space according to Euclid. Dilation is a transform that modifies an object's size. The process of dilation is used to enlarge or reduce items. The result of this transformation is an image that is a perfect replica of the original shape. However, there is a variation in the shape's size. The initial form ought to be distorted by dilation.
A dilation is a transformation that yields a different-sized picture with the same general shape as the original. The scale factor (also known as the dilation constant) and the dilation center are included in the description of a dilation. A fixed point in the plane around which all points are enlarged or contracted is the center of a dilation.

y is inversely proportional to x squared y=8 when x =3.5 find the neagative value of x when =8/9
Since y is inversely proportional to x squared and y = 8 when x = 3.5, the negative value of x when y = 8/9 is equal to -10.5 or -21/2.
What is an inverse variation?In Mathematics, an inverse variation can be modeled by this mathematical expression:
y ∝ 1/x
y = k/x
Where:
x and y represents the variables or data points.k represents the constant of proportionality.Based on the information provided above, we would determine the constant of proportionality (k) by substituting the value of the given variable as follows:
y = k/x²
k = yx²
k = 8(3.5)²
k = 98.
Now, we can determine the negative value of x:
x = √(k/y)
x = √(98/(8/9)
x = √110.25
x = 10.5 or 21/2.
x = -10.5 or -21/2.

Find the removable and non removable discontinuity.

The function F(x) = 2/x has a removable discontinuity at x = 0, and a non-removable discontinuity at x = 0.
What is the Function?
A function is a mathematical relation between a set of inputs, called the domain, and a set of possible outputs, called the range. The definition of a function is often written as "f: X → Y", where X is the domain and Y is the range, and "f" is the name of the function.
The function F(x) = 2/x has a removable discontinuity at x = 0, and a non-removable discontinuity at x = 0.
At x = 0, the function is not defined, so it has a removable discontinuity at x = 0.
However, since the function is not defined for x = 0, it is also a non-removable discontinuity at x = 0.

Adding several variables to a regression analysis can help do which of the following?
A. Increase the statistical significance of the results
B. Control for several variables at once
C. Increase the construct validity of a study
D. Test for temporal precedence
Regression analysis is mostly used when you want to predict a continuous dependent variable from a several number of independent variables. If the dependent variable is dichotomous, then logistic regression can be used.
If the break between the two levels of the dependent variable is nearly to 50-50%, then we can use both logistic and linear regression will end up giving you similar results.
If you have inserted the data (rather than using an established dataset), it is a nice idea to check the accuracy and the consistence of the data entry.
If you do not want to re-check all the data point, you should at least check the minimum and maximum value for all the variable to ensure that all values for each variable are "valid" or not.

Based on the descriptions of two lines, a statement which is true include the following: C. Line 1 is neither parallel nor perpendicular to Line 2.
How to calculate the slope of a line?In Mathematics, the slope of a straight line can be calculated by using this this mathematical expression;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
From the information provided above, we have the following data points on the line:
Points on x-axis of line 1 = (-4, 9).Points on y-axis of line 1 = (17, -9).Substituting the given points into the slope formula, we have the following;
Slope, m = (y₂ - y₁)/(x₂ - x₁)
Slope, m = (-9 - 17)/(9 - (-4))
Slope, m = -26/(9 + 4)
Slope, m = -26/13
Slope, m = -2
For the slope of line 2, we have:
Slope, m = (y₂ - y₁)/(x₂ - x₁)
Slope, m = (19 - 1)/(-5 - 1)
Slope, m = -18/6
Slope, m = -3
In conclusion, we can logically deduce that both lines are neither parallel nor perpendicular because their slope differs.
