Answer:
m = -7
initial value = 27
Step-by-step explanation:
The rate of change is also known as the slope of a line.
To find this do y1-y2/x1-x2 or y2-y1/x2-x1. You can't do rise/run in this case because there is no graph. I will help you with both answers for the first question only, because I think it is better for you to also practice.
The initial value is also when x = 0, therefore the initial value is 27.
The slop is:
27-(-8)/0-5
35/-5
-7
The rate of change, or slope, for the first question is -7.
Is that the top or bottom? Assuming it's the top, when distributing the -2 to what's inside the parenthesis, they were correct in multiplying -2•7, but when they multiplied -2 and -y, the answer needs to be positive 2y because they are multiplying double negatives
Answer:

Answer:
D
Step-by-step explanation:
f(x) + g(x) means you add whatever f(x) is to g(x)
2x^2 -4x - 3 + (2x^2 - 16) = 4x^2 -4x -16
