By identifying the intersection between the graphs, we conclude that the solution is (-3, 4).
How to solve the system of equations?To graphically solve a system of equations, we need to graph the equations of the system in the same coordinate axis, and then find the intersection points between the graphs.
Here we already have the equations graphed, so we only should find the points of intersection.
We can see two red lines, we can see that the lines intersect at the point (-3, 4). This means that the solution of the system of equations is the point (-3, 4).

According to the graph, what is the value of the constant in the equation
below?
Answers
Answer:
A
Step-by-step explanation:
height (y-axis) = constant × width (x-axis)
let's look at the point coordinates.
remember, an ordered pair of point coordinates consists of an x value and an associated (typically calculated by a function) y value.
we see that all y values are half of the x values (3 and 1.5, 2 and 1, 7 and 3.5, 8 and 4).
so, the constant in our equation is responsible for returning half of the x value back as the y value.
what constant factor turns a number in half ?
x × c = x/2
c = 1/2
and so, A is the right answer.

$109.95
$114.50
$120.99
$131.25
Answers
The break-even sales price per umbrella if sun cover manufactures the units is $120.99.
How to calculate the sales price?This can be done by using the formula:
Break even units = Total fixed cost / (Price - Variable cost)
8573 = 675921/(Price - 42.15)
8573(P - 42.15) = 675921
8573P - 361351.95 = 675921
8573P = 675921 + 361351.95
8573P = 1037273.4
P = 1037273.4/8574
P = $120.99
Therefore, the price is $120.99.

HELP ASAP PLEASE (answer all parts please)
The upcoming championship high school football game is a big deal in your little town. The problem is, it is being played in the next biggest town, which is two hours away! To get as many people as you can to attend the game, you decide to come up with a ride-sharing app, but you want to be sure it will be used before you put all the time in to creating it. You determine that if more than three students share a ride, on average, you will create the app.
You conduct simple random sampling of 20 students in a school with a population of 300 students to determine how many students are in each ride-share (carpool) on the way to school every day to get a good idea of who would use the app. The following data are collected:
6 5 5 5 3 2 3 6 2 2
5 4 3 3 4 2 5 3 4 5
You will construct a 90% confidence interval and 95% confidence interval for the mean number of students who share a ride to school, then you will compare and interpret the results.
Part A: Decide which partner will construct each confidence interval, and then state the parameter and check the conditions.
Part B: Construct the confidence interval. Be sure to show all your work, including the degrees of freedom, critical value, sample statistics, and an explanation of your process.
Part C: Interpret, share, and compare. Interpret the meaning of the confidence interval, compare your results with your partner, and describe the difference in the width of the interval and the margin of error.
Part D: Use your findings to explain whether you should develop the ride-share app for the football game.
Answers
How to calculate the probability?
The confidence interval based on the information will be:
= 3.85 - 2.09(1.348 / ✓20)
= 3.22
Also, 3.85 + 2.09(1.348 / ✓20) = 4.48
The confidence interval simply means that one is 95% confident that the true mean is between 3.22 and 4.48.
Find the ratio of the perimeter for the pair of similar two regular pentagons with areas 144 in² and 36 in²
Answers
The ratio between the perimeter of the largest and smallest pentagon is 2.
How to find the ratio between the perimeters?We know that the pentagons are similar, meaning that the dimensions of one of the pentagons is k times the dimensions of the other.
Because of this, the ratio between the areas is k squared. And because the perimeter depends linearly on the dimensions, the ratio between the perimeters will be equal to k.
So we need to find k, we will have:
[tex]\frac{144 in^2}{36 in^2} = k^2 = 4\\\\k = \sqrt{4} = 2[/tex]
Then we conclude that the ratio between the perimeters is k =2.

Use Cramer’s rule to solve for x: x + 4y − z = −14 5x + 6y + 3z = 4 −2x + 7y + 2z = −17
Answers
Looks like the system is
x + 4y - z = -14
5x + 6y + 3z = 4
-2x + 7y + 2z = -17
or in matrix form,
[tex]\mathbf{Ax} = \mathbf b \iff \begin{bmatrix} 1 & 4 & -1 \\ 5 & 6 & 3 \\ -2 & 7 & 2 \end{bmatrix} \begin{bmatrix} x \\ y \\ z \end{bmatrix} = \begin{bmatrix} -14 \\ 4 \\ -17 \end{bmatrix}[/tex]
Cramer's rule says that
[tex]x_i = \dfrac{\det \mathbf A_i}{\det \mathbf A}[/tex]
where [tex]x_i[/tex] is the solution for i-th variable, and [tex]\mathbf A_i[/tex] is a modified version of [tex]\mathbf A[/tex] with its i-th column replaced by [tex]\mathbf b[/tex].
We have 4 determinants to compute. I'll show the work for det(A) using a cofactor expansion along the first row.
[tex]\det \mathbf A = \begin{vmatrix} 1 & 4 & -1 \\ 5 & 6 & 3 \\ -2 & 7 & 2 \end{vmatrix}[/tex]
[tex]\det \mathbf A = \begin{vmatrix} 6 & 3 \\ 7 & 2 \end{vmatrix} - 4 \begin{vmatrix} 5 & 3 \\ -2 & 2 \end{vmatrix} - \begin{vmatrix} 5 & 6 \\ -2 & 7 \end{vmatrix}[/tex]
[tex]\det \mathbf A = ((6\times2)-(3\times7)) - 4((5\times2)-(3\times(-2)) - ((5\times7)-(6\times(-2)))[/tex]
[tex]\det\mathbf A = 12 - 21 - 40 - 24 - 35 - 12 = -120[/tex]
The modified matrices and their determinants are
[tex]\mathbf A_1 = \begin{bmatrix} -14 & 4 & -1 \\ 4 & 6 & 3 \\ -17 & 7 & 2\end{bmatrix} \implies \det\mathbf A_1 = -240[/tex]
[tex]\mathbf A_2 = \begin{bmatrix} 1 & -14 & -1 \\ 5 & 4 & 3 \\ -2 & -17 & 2 \end{bmatrix} \implies \det\mathbf A_2 = 360[/tex]
[tex]\mathbf A_3 = \begin{bmatrix} 1 & 4 & -14 \\ 5 & 6 & 4 \\ -2 & 7 & -17 \end{bmatrix} \implies \det\mathbf A_3 = -480[/tex]
Then by Cramer's rule, the solution to the system is
[tex]x = \dfrac{-240}{-120} \implies \boxed{x = 2}[/tex]
[tex]y = \dfrac{360}{-120} \implies \boxed{y = -3}[/tex]
[tex]z = \dfrac{-480}{-120} \implies \boxed{z = 4}[/tex]

2(z+5) +5(z+ 2) = 10(z − 1)
Answers
Answer:
z = 10
Step-by-step explanation:
First apply multiplication to inside the parenthesis:
2(z+5) = 2z + 10
5(z+ 2) = 5z + 10
10(z − 1) = 10z - 10 now write the full equation
2z + 10 + 5z + 10 = 10z - 10 add like terms
7z + 20 = 10z - 10 transfer like terms to the same side of the equation
20 + 10 = 10z - 7z
30 = 3z divide both sides by 3
10 = z

what is the volume of a cone with a radius of 4x and a height of 21xy^2?
Answers
The volume of a cone with radius of 4x and a height of 21xy² is 352 x³y²
How to calculate the volume of a cone
Using the formula:
V=πr²h/3
Where r= radius = 4x
h= height = 21xy∧2
Substitute the values into the equation
V = 22/7 × 4x × 4x × (21 × x × y × y) ÷ 3
V = 22/7 × 16x² × 7xy²
V= 22 × 16x² × xy²
Multiply all through
Volume, V = 352 x³y²
Therefore, the volume of the cone is 352 x³y²
