Answer:
(f+g)(x) = x^2 +10x +7
Step-by-step explanation:
(f+g)(x) = f(x) +g(x) = (15x +7) +(x^2 -5x)
= x^2 +x(15 -5) +7
= x^2 +10x +7
Answer:
the estimated difference is 4
Step-by-step explanation:
The estimated difference of 12 9/11 - 8 13/15 would be rounding the fractions to a whole number
12 9/11 becomes 12 11/11 which is 13
8 13/15 becomes 8 15/15 which is 9
we rounded each fraction up since each fraction was above the half way mark so the new equation is,
13 - 9 = 4
Answer:
f9
Step-by-step explanation:
The pool is drained at 700 gallon per hour , so you need to multiply the number of hours ( t) by 700 to find the total number of gallons after a certain amount of hours, this would be written as 700t.
You would then need to subtract that amount from the starting value of 28,000.
This would make the equation g = 28,000 - 700t.
