Answer:
(x^2) + 1 = y
Step-by-step explanation:
To check, you can just plug in the x values given. It should equal to its given y value.
Well let's see
Gas-3,6,9,12,15,18,21,24,27
Wash-8,16,24,
So on the 24th day.
To simplify into 1 fraction, remember, we must make the denominator the same
x/ (x-1 ) - 1/ (2-2x)
= -x/ -(1-x) - 1/(2-2x) [see the similarity now? ] [whatever we multiply for the denominator, as long as we multiply to the numerator, it will be ok]
= -2x / -(2-2x) + 1/-(2-2x)
= (-2x+1 )/ -(2-2x)
=(2x-1)/(2-2x)
16x-15-9x=13
7x-15=13
+15 +15
x=4
-4x +8y = 24
8y = 24+ 4x
y = 24/8 + 4x/8
y = 3+ x/2
Hope it helps!
