8x10 = 80
4x4 = 16
2x4 divided 2 = 4
80+16+ 4 = 100
Answer: y= -x +4
negative slope because our graph goes down as we go right.
+4 indicating how high on our y axis we go up/down
Answer:
A
Step-by-step explanation:
A is the only answer with ordered pairs that have a consistent rate of change, -1/3
Answer: We should add the constant 81 to the expression to have a perfect square trinomial.
The perfect square trinomial that would be formed would result from (x + 9)^2.
We can use foil to prove it.
(x + 9)(x + 9)
x^2 + 9x + 9x + 81
x^2 + 18x + 81
81 is the value that must go with 18x in the middle to form the perfect square trinomial.
