She has 2 $20 and 1 $10 bills.
Since it says that she has 1 more 20 dollar bill, we should subtract 50 by 20.
That gives us 30.
Then we should subtract it AGAIN, 30 by 20.
That gives us ten.
Finally, well subtract that, 10 by 10.
Equation:
[50-(20x2)]-10

Half a number increased by 10 is equal to 35 less than twice the number. What is the number?
faust18 [17]

Answer:

x=10

Step-by-step explanation:

x/2 + 10 = 35 - 2x

x/2 + 2x = 35 - 10

5x/2 = 25

5x = 25.2

5x = 50

x = 50/5

x = 10

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).
