Answer:

Step-by-step explanation:
difference of a number and 9 means to subtract

twice that means multiply by 2

at least is greater than or equal to

Answer: C. (-7x+9)(x-2)
Step-by-step explanation:
1. Factor out the negative sign.
−(7x^2+5x−18)
2. Split the second term in 7x2+5x−18 into two terms.
−(7x^2+14x−9x−18)
3, Factor out common terms in the first two terms, then in the last two terms.
−(7x(x+2)−9(x+2))
4. Factor out the common term x+2x+2x+2.
−(x+2)(7x−9) or (-7x+9)(x-2)
Answer:
The solution to the given inequality is a > 8.
Step-by-step explanation:
For this problem, we have to solve for the inequality.
9a - 24 > 48
add 24 on both sides of the inequality.
9a > 72
Divide 9 on both sides of the inequality.
a > 8
So, your solution would be a > 8.
