Write a linear equation in slope intercept form to model the situation and internet company charges $4.95 per month plus $2.50 for each hour of use how much would it cost in a month when you use the internet for 14 hours

it cost $39.95 in a month when you use the internet for 14 hours

Step-by-step explanation:

internet company charges $4.95 per month plus $2.50 for each hour

Let x be the amount of hours internet used

for 1 hour, charge is 2.50

for x hours , charge is 2.50x

To get linear equation we use y=mx+b

m is the slope and b is the fixed cost

fixed cost b= 4.95 and slope m = 2.50

So equation becomes y = 2.50x + 4.95

we need to find the cost y for 14 hours

So we plug in 14 for x  and find out y

y = 2.50(14) + 4.95= 39.95

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
