The table shows the amount earned for washing cars. How much is earned for washing 25 cars? 3 cars=$13.50, 6 cars=$27, 9 cars=$4

katrin2010 [14]

You need to find out how much it costs to wash one car, so:

3×=13.50
Divide both sides by 3.
x=4.5 per car.
Now multiply 4.5 by 25 which should give you $112.50

A ride on the roller coaster costs 4 tickets while the boat ride only costs 3 tickets. Michael went on the two rides a total of

True [87]

Let x = roller coaster ticket
let y = boat ride ticket

x + y = 10
4x + 3y = 37

x = 10 - y
4x + 3y = 37
4(10-y) + 3y = 37
40 - 4y + 3y = 37
-y = 37 - 40
-y = -3
y = -3/-1
y = 3

x = 10 - y
x = 10 - 3
x = 7

x = 7 ; y = 3

4x + 3y = 37
4(7) + 3(3) = 37
28 + 9 = 37
37 = 37

First answer gets brainiest answer

Vladimir79 [104]

A is true. There is no vertical line that can intersect this graph twice.

B is false. The function is defined for all $x \geq -2$ .

C is true. The minimum value of $y$ is $2$ .

D is false. The piecewise function is made of one semicircle and one line, just two functions.

E is also false. The circular arc is a nonlinear function.

Thus, the answer is A and C.
