6 0

1. <span>4x – 20 = 5y

so 5y = </span><span>4x – 20

divide both sides by 5

y = (4/5)x - 4

2. x-intercept is at y=0

so (4/5)x - 4 = 0

x = 5

so it is (5,0)

3. y-intercept is at x=0, y = 0 - 4 = -4

so it is (0,-4)

If one gallon is the same amount as 4 quarts, how many quarts are in 5 gallons?

wlad13 [49]

If one gallon = 4 quarts
Then 5 gallons = x quarts

To solve this we can set up a porportion

1/4 = 5/x

To solve the porportion we need to find the rule so how to we get to 4 from 1? Well we can multiply 1 by 4 to get one right?

So if this is true, 1 x 4 = 4 then 5 x 4 must equal x

5 x 4 = 20 so the answer would be 20 quarts are in 5 gallons

Another way to look at this is that you have 5 gallons and in each gallon is 4 quarts to if there is 4 quarts in every one gallon then that’s just 4 + 4 + 4 + 4 + 4 or 5 x 4

I hope this helps! <3
