Nancy is trying to decide which cell phone plan would be the right one for her. She has narrowed her choices down to two, Spirit and Horizon. Spirit (s) has a fixed fee of $20 and an
additional charge of 5 cents per minute. Horizon (h) has no fee and charges 15 cents per minute.
Write two equations that could be used to determine the total cost for each plan for 300 minutes?
A. s = 5x + 20
h=15x

B. s = 0.05x + 20
h = 0.15x

C. s = 15x
h = 5x + 20

D. s = 0.15x
h = 0.05x + 20

y/x=18

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

answer: plz put a pic in so i can answer it

step-by-step explanation:

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
