First fill in the blank box is 2 second is 8 third is 80
Flat rate=y intercept
rate per mile=slope
y=3x+10 would be it
1.
3 is the value of the slope (3 dollars per mile)
2.
y intercept is (0,10)
3.
22 miles
y=3(22)+10
y=66+10
y=76
$76
What I did was turn ¾ in to a fraction (which is 75%) then turned it into a decimal (.75)
then I multiplied .75 by 1.20 and .9
So she spent 90 cents on apples
Hope I helped :)
As y varies directly with x, there is a proportionality constant. As x increases by that certain constant, y also increases. We equate:
y = kx
where k = proportionality constant.
Given the condition, y = 5 when x = 4, then we solve for k:
5 = k(4)
k = 5/4 or 1.25
When y = 8, then
8 = (5/4)(x)
x = 8/(5/4) = (8)(4/5) = 32/5 or 6.4 (ANSWER)
