An internet service provider (ISP) conducts a survey in two cities - city A and city B - to analyze how an increase in the current cost of a plan would affect the number of subscribers of the company. The scatter plot shows the results. An increase in the cost of the plan would have a greater impact on the number of subscribers of the ISP in?
because the?
is greater than the?

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

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
