A cell phone plan costs $150 to start, Then, thero is a $50 charge each month. What is the total cost, y, for x months? Which equation match this situation Y=150-50x. Y=50x+150. Y=150x+50. -50x+150=y

Y = 50x + 150

Step-by-step explanation:

50 per month (x = unknown number of months) === 50x

$150 is the starting charge (automatic +150)

Y = total cost

Y = 50x + 150

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

(x, y)→(x − 8, y − 7)

step-by-step explanation:
