Six would be your answer
Step-by-step explanation:
2y-9= y-2
-y -Y
y-9=-2
y=-2+9
y=6
The table is attached.
A) The gasoline consume grows as the distance traveled increases. This means that the two quantities are directly proportional.
Therefore, the proportionality constant is given by:
k = gasoline / distance
= 2 / 40
= 0.05
We could have used also:
k = 3 / 60
= 0.05
In order to find the gasoline consumed, you need to multiply the distance by the proportionality constant:
30 × 0.05 = 1.5
55 × 0.05 = 2.75
In order to find the distance traveled, you need to divide the gasoline consumed by the proportionality constant:
3.5 ÷ 0.05 = 70
B) The function of the proportionality found is:
y = 0.05·x
where:
x = distance
y = gasoline
Therefore:
y = 0.05·110 = 5.5
Femi for a trip of 110 miles expects to use 5.5 gallons of gasoline.

Answer:
Step-by-step explanation:
Let the amount donated to City Youth Fund = $x
And the amount donated to the Educational Growth Foundation = $y
Amount donated to the Educational Growth Foundation is at least four times the amount donated to City Youth Fund.
y ≥ 4x ------(1)
Total amount she can donate is up to $440
x + y ≤ 440 ------(2)
And the constraints are x ≥ 0 --------(3)
y ≥ 0 ------(4)
And solution set will be the common shaded area of both inequalities as shown in the graph attached.
(By using a graphing tool we can find the graph).
