Domain is the x-values
Range is the y-values
To identify the range, plug in the x-values they gave you into the equation to find its y-value
x = 3
y = 2x + 4 Plug in 3 for x
y = 2(3) + 4
y = 10
x = 5
y = 2x + 4 Plug in 5 for x
y = 2(5) + 4
y = 10 + 4
y = 14
x = 6
y = 2x + 4 Plug in 6 for x
y = 2(6) + 4
y = 16
x = 8
y = 2x + 4 Plug in 8 for x
y = 2(8) + 4
y = 20
The range is {10, 14, 16, 20}
Let the total number of gum balls in the jar be x, then the number of blue balls in the jar is 0.2x and the number of green balls is 10 + 0.2x and the number of red balls are 0.5(0.2x) = 0.1x.
Let the initial number of yellow balls in the jar be y, then

The initial number of white balls was 0.275x.
Thus,

Thus, the initial number of yellow balls was 0.175x = 0.175(200) = 35.
The initial number of white balls was 0.275x = 0.275(200) = 55.
One-fifth of white balls = 1/5(55) = 11.
Therefore, the number of yellow balls in the jar was 35 + 11 = 46.
The answer is 2.76 because u round it 2 places to the right
