From the second equation y=-1-x so we can write -2x²+3x-1=-1-x.
So -2x²+4x=0, 2x(-x+2)=0, therefore x=0 or 2 and the corresponding y values are -1 and -3.
We can write the answers as ordered pairs (0,-1) and (2,-3).
Answer:
12
Step-by-step explanation:
Answer:
The missing x would be 6
Step-by-step explanation:
To find the missing value fo x, use the slope formula and solve for the missing variable.
m(slope) = (y2 - y1)/(x2 - x1)
-3 = (8 - -4)/(2 - x)
-3 = 12/(2 - x)
Now we cross multiply to solve.
12 = -3(2 - x)
12 = -6 + 3x
18 = 3x
6 = x
Add 2 to 3 and get 5 add 3 and get 8 add 5 to get 13 add 8 to get 21
Answer:
Answer is below
Step-by-step explanation:
Subtract 16 from both sides.
![-8s+16(-16)=56(-16)\\-8s=40](https://tex.z-dn.net/?f=-8s%2B16%28-16%29%3D56%28-16%29%5C%5C-8s%3D40)
Divide both sides by -8
![\frac{-8s}{-8}=\frac{40}{-8} \\s=-5](https://tex.z-dn.net/?f=%5Cfrac%7B-8s%7D%7B-8%7D%3D%5Cfrac%7B40%7D%7B-8%7D%20%5C%5Cs%3D-5)
