Answer:

Step-by-step explanation:

Let's solve one of them for x.

Add 4

Divide by 3.

Now, plug the value of y in the formula, or you can plug the value of x in the other equation. I'll take this one.




Multiply by 3 to get rid of the denominator.

add x

Combine like terms;

Divide by 4.

Simplify.

Now that you found the value of x, replace it in any of the equations to find y.


Proof:




Answer:
(7, 0) and (-5, 0)
Step-by-step explanation:
<u>Vertex form</u>
(where (h, k) is the vertex)
Given:

Given:



Therefore:

The x-intercepts are when y = 0






Therefore, the x-intercepts are (7, 0) and (-5, 0)
Answer:
- 9/2
Step-by-step explanation:
slope m = (y2 - y1) /(x2 - x1) = (14 - 5)/(1 - 3)= 9/(-2)= - 9/2
