7/5
Step-by-step explanation:
Everything is positive as I explained,
the answer of the reverse reciprocal is 7/5 because 7/5 is parallel to -5/7 so they are perpendicular to each other.
Answer:
Aaliyah is 18years old now
Step-by-step explanation:
let AJ's age=x
Aaliyah's age=3x
Four years ago,
AJ's age=x-4
Aaliyah's age=3x-4
3x-4=7(x-4)
3x-4=7x-28
3x-7x=-28+4
-4x=-24
x=6
Aaliyah's present age=3x=3×6=18
Answer: the effect is to bring the graph of the original cost function, f(x) 12 units downward.
Explanation:
1) Being the original cost function f(x) = ax + b, if property taxes, which are part of the fixed costs, are decreased by $12,000 per year, the new cost function will be:
g(x) = ax + b - 12 ↔ note that I use 12 and not 12,000 thousands, because b and a are told to represent costs in thousands of dollars.
Therefore, g(x) = f(x) - 12. Meaning that the effect is to shift the graph of the original cost function, f(x) 12 units downward.
