PLEASE HELP!!!!!<br> will mark brainliest!!!!!
zmey [24]

Answer:

Table:

1: f(x) = 5

2: f(x)= 6

5: f(x) = 9

Points: (1,5), (2,6), and (5,9)

Step-by-step explanation:

1. The function f(x) = x + 4 means that 4 is added to the input, x, to get the output, y.

  • f(x) = 1 + 4 = 5
  • f(x) = 2 + 4 = 6
  • f(x) = 5 + 4 = 9  

Therefore, when x = 1 then f(x) = 5, x = 2 then f(x) = 6, and x = 5 then f(x) = 9.

2. Now, to find the points, we must know that x is the x-coordinate and f(x) is the y-coordinate of the point. Because of this, the points are:

  • (1,5)
  • (2,6)
  • (5,9)

Therefore, the points are (1,5), (2,6), and (5,9).

I 10. One day, Timmy works 4 hours and makes an additional $50 in tips. Another day, he works 6 hours and gets an additional $70
VARVARA [1.3K]

Answer:

$8.50/h

Step-by-step explanation:

I am unsure of the - in the equation. This should be 4h+50+6h+70=M

then we would set the equation equal to the $205

205=4h+50+6h+70

if we simplify we have

205=10h+120

then we would get the h by itself and we get

205-120=10h

85.00=10h

85.00/10=10h/10

8.50=h
