For his long long distance phone service chris pays a $6 monthly fee plus 8 cents per minute. last month, chris's long distance bill was $11.52. for how many minutes was chris billed

total bill would be X=6.00 +0.08m

where m = minutes

X = total bill

so 11.52 = 6.00+0.08m

subtract 6 from each side

5.52 = 0.08m

 now divide both sides by 0.08

5.52/0.08 = 69

 he was billed for 69 minutes.

D. f(x)=3^x+4

Step-by-step explanation:

The graph crosses the y axis at 5 so the y intercept is 5

Anything to the zero power is 1

A. f(0)=4^0+4  = 1+4 =5

B. f(0)=4^0+5 =1+5 =6

C. f(0)=3^0+5 =1+5 =6

D. f(0)=3^0+4=1+5 =5

We can eliminate choices b and c

A. f(x)=4^x+4

D. f(x)=3^x+4

Let x = 2, y = is between 12 and 14

A. f(2)=4^2+4=16+4 =20

D. f(2)=3^2+4=9+4 = 13

So A is eliminated
