Answer: the peaches were a lighter shade of orange
Solve the first for y
y=13x-90 and the second is y=x^2-x-42
When there is/are solutions y=y so we can say:
x^2-x-42=13x-90 subtract 13x from both sides
x^2-14x-42=-90 add 90 to both sides
x^2-14x+48=0 expand so that it is easy to factor...
x^2-6x-8x+48=0 now factor 1st and 2nd pair of terms
x(x-6)-8(x-6)=0
(x-8)(x-6)=0
So there are two solutions, when x=6 and 8.
Using either original equation we can find the corresponding values for y. I'll use y=13x-90 because it is easier...
y(6)=-12, y(8)=14 so the two solutions are the points:
(6,-12) and (8,14)
Ten times two point five plus thirteen point five
10 x (2.5 + 13.5) = 160
Hope this helps

Answer:
18
Step-by-step explanation:
Subtract 6 from both sides so the equation becomes 1/9x=2. Multiply by the reciprocal on both sides (9)1/9x=2(9).
This cancels out to x=18
Answer:
20 minutes; 240 barrels
Step-by-step explanation:
Old line = 40 + 10t
New line = 12t
Equal when,
40 + 10t = 12t
40 = 2t
t = 20 minutes
Each line will have:
12t = 12(20) = 240 barrels
