The equation y=3.2x represents the cost y (in dollars) for a taxi ride during peak hours that costs x dollars during off-peak hours. a. Solve the equation for x.

x = y / 3.2

Step-by-step explanation:

Given:

y = 3.2x

Where

y = cost for a taxi ride during peak hours (in dollars)

x = cost for a taxi ride during off-peak hours (in dollars)

Solve the equation for x.

y = 3.2x

Divide both sides by 3.2

y / 3.2 = 3.2x / 3.2

y / 3.2 = x

x = y / 3.2

This means,

Cost for a taxi ride during off-peak hours (in dollars) = Cost for a taxi ride during peak hours (in dollars) / 3.2

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
