Answer:
y = -3x + 18
Step-by-step explanation:
y = mx + b
m = -3
6 = (-3) * 4 +b
b = 6 - (-3) * 4
b = 6 +12
b = 18
y = -3x + 18
Well if you know the top and the bottom are equal and the two sides are equal. So just add them up
Answer: 23
If x=-1 then (-1) to the power of 3 = -1 and (-1) to the power of 2= 1
3(-1)^3= -3
2(-1)^2= 2
-3+2+25= 23
Answer: k(0) = 4; k (2x - 7) = 2x -3
Step-by-step explanation:
If k(a) = a + 4
K(0) will be 0 + 4
K(0)= 4
Then, k (2x - 7) = 2x -7 +4
K (2x - 7) = 2x - 3
