Y=4x−9<br> Complete the missing value in the solution to the equation
weeeeeb [17]

Answer:

<h2>The missing value is 3, and the coordinates are (3,3).</h2>

Step-by-step explanation:

The complete question is

y=4x-9

Complete the missing value in the solution to the equation. (3, ? )

By given, we know that x=3, because coordinates are written like (x,y).

Then, we replace the given coordinate to find y.

y=4x-9\\y=4(3)-9\\y=12-9\\y=3

Therefore, the missing value is 3, and the coordinates are (3,3).

I NEED HELP ON THIS CONSTRUCTED RESPONSE QUESTION! :(
zavuch27 [327]

Answer:


Step-by-step explanation:

She bought 18 ride tickets at $0.75 per ticket, so she spent 18 * $0.75 = $13.50 on rides. She spent a total of $33.50 for only admission and rides.

$33.50 - $13.50 = $20

Admission is $20.

(a) Let y represent total cost. Let x represent the number of ride tickets.

(b) y = 0.75x + 20

(c) The total cost is the cost of x ride tickets plus the admission.

x ride tickets cost 0.75x.

Admission is a fixed 20.

Adding the cost of ride tickets, 0.75x, to the admission cost, 20, gives you the total cost, y.
