Answer: x = - 19
y = 55
Step-by-step explanation:
y = - 3x - 2 (1)
5x + 2y = 15 (2)
substitute y = - 3x - 2 into equation (2)
equation (2) becomes
5x + 2 (-3x - 2) = 15
5x + ( - 6x - 4) = 15
opening the bracket
5x - 6x - 4 = 15
collecting like terms
5x - 6x = 15 + 4
-x = 19
x = - 19
substituting x = - 19 into equation 1
y = - 3x - 2
y = - 3 (-19) - 2
y = 57- 2
y = 55
To find the area of a polygon use the formula Area = 1/2 x perimeter x apothem
Answer:
6
Step-by-step explanation:
1. (-5,-12)
2. (3,-4)
To identify the constant H and K
- You need to write the given equation in vertex form
- Use complete the square method to write in vertex form
- The vertex form is

- after writing the equation in the world storm you can see that there is a h and a k
- Pull the h and the k in into (h,k)
I can't do all of it so I'll do 2 for you and with explanations.
