Which systems of equations intersect at point A in this graph?

abruzzese [7]

Answer:

The point of intersection of the system of equations is:

(x, y) = (-2, 1)

The correct system of equations intersect at point A in this graph will be:

$\begin{bmatrix}y=4x+9\\ y=-3x-5\end{bmatrix}$

Thus, the second option is correct.

Step-by-step explanation:

Given the point

A (-2, 1)

Let us check the system of equations to determine whether it intersect at point A in this graph.

Given the system of equations

$\begin{bmatrix}y=4x+9\\ y=-3x-5\end{bmatrix}$

Arrange equation variable for elimination

$\begin{bmatrix}y-4x=9\\ y+3x=-5\end{bmatrix}$

$y+3x=-5$

$-$

$\underline{y-4x=9}$

$7x=-14$

so the system of equations becomes

$\begin{bmatrix}y-4x=9\\ 7x=-14\end{bmatrix}$

Solve 7x = -14 for x

$7x=-14$

Divide both sides by 7

$\frac{7x}{7}=\frac{-14}{7}$

Simplify

$x = -2$

For y - 4x = 9 plug in x = 2

$y-4\left(-2\right)=9$

$y+4\cdot \:2=9$

$y+8=9$

Subtract 8 from both sides

$y+8-8=9-8$

Simplify

y = 1

Thus, the solution to the system of equations is:

(x, y) = (-2, 1)

From the attached graph, it is also clear that the system of equations intersects at point x = -2, and y = 1.

In other words, the point of intersection of the system of equations is:

(x, y) = (-2, 1)

Therefore, the correct system of equations intersect at point A in this graph will be:

$\begin{bmatrix}y=4x+9\\ y=-3x-5\end{bmatrix}$

Thus, the second option is correct.

Select ALL that apply: 21 days is equal to...

Sonbull [250]

1 week is 7 days.

3 weeks = 21 days. Answer D. is correct.

A hour is 3600 seconds

24 hours ( a day ) is 86400 seconds

21 days is 1814400 seconds. * This is not an option *

Since 24 hours are in a day 24 hours x 21 days is 504 hours

Answer A. is correct

504 hours x 60 minutes per hour is 30240

Answer B. is correct. These are all the correct answers, A,B, and D.

PLEASE SOLVE DUE RIGHT NOW!!!!!!!!!!!!

erma4kov [3.2K]

Solution:

We know that:

$Area \ of \ triangle = \dfrac{1}{2} \times Base \times Height$

Since we are already given the base and the height, we can substitute them into the formula to find the area of the triangle.

$Area \ of \ triangle = \dfrac{1}{2} \times 18 \times24$

Cancel out the "2" by dividing it by 18.

$Area \ of \ triangle = 9 \times24$

Simplify the multiplication.

$\bold{Area \ of \ triangle = 216 \ ft^{2}}$

The cost to a rent paddle boat at the county park is $8 per hour if x represent the number off hours the boat is rented and for

bazaltina [42]

Answer:

10+8x=y

Step-by-step explanation:

The 10$ is added on because it's a one time exchange and the 8 is multiplied by the x because for every hour you add 8$ to the price and y is the total price at the end depending on x.
