Plan A at 60 calls : 60*.25 + 25 = 15 + 25 = 40
Plan A is equal plan B at 60 calls
So if more than 60 calls the plan B will cost less than plan A
Answer: more than 60 calls
Answer: FALSE .

For two (2) angles to be supplementary, they must add up to 180° ;
and the two angles given — 98° and 72° — add up to 170°.
{Note: 98 + 72 = 170 — NOT "180" ; and as such are NOT supplementary.}.

Answer:
f(x) = -5x + 16
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Define
y + 5x = 16
Step 2: Put into slope-intercept form
- Subtract 5x on both sides; y = -5x + 16
Step 3: Rewrite in function notation
f(x) = -5x + 16
