C=8h+12
the 8h represents the $8 per hour for renting the boat, and h represents however many hours you rent the boat for. The +12 is the initial $12 fee. This is in slope intercept form, just using different variables than y=mx+b
How much part can sally paint in an hour ?
a ÷ 7 = a/7
And what about Steve ?
a ÷ 9 = a/9
Where, a is the total area of the room.
So, let the time taken by both of them to paint the room together be 't'
So,
t(a/7 + a/9) = a
t(9a/63 + 7a/63) = a
t(16a/63) = a
t = 63/16 ≈ 4 hr
The y intercept is at 2 and the x intercept is at 3
37.1
35 * .06 = 2.1
35 + 2.1 = 37.1
I'm not amazing at fractions but it equals:
1/3 x4= 4/3
so 1 1/3 as mixed fraction
