Find the value of x so that the function has the given value.

j (x) = -4/5x + 7; j (x) = -5

x = 15

Step-by-step explanation:

Step 1: Define

j(x) = -4/5x + 7

j(x) = -5

Step 2: Substitute and Evaluate

-5 = -4/5x + 7

-12 = -4/5x

x = 15

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
