Answer:
The rate of change: 1/5
Initial value: (0,-1)
Step-by-step explanation:
The rate of change is easily 5/25, we just have to simplify it to 1/5.
To get the intial value, just subtract (2,9) by the rate of change twice.
It's linear and equation of the function is :
f ( x ) = 2x - 1
17
linear has 1 as highest exponent
D has x^2
D is not linear
18. find slope
(y2-y1)/(x2-x1)=(-1-2)/(0-4)=-3/-4=3/4
y=3/4x+b
B is answer
The diameter is twice as big as the radius
1 pack has 5 seperate packs, each with 10 pieces
=>50 pieces
50*3=150 pieces of gum
