The inequality is in the direction of the arrow
The arrow is like this <——— so the inequality is <
It is an open circle so that means -1 is not included
x<-1
Or choice A
Answer:
Yes.
Step-by-step explanation:
Perfect square trinomials and difference of two squares are just to binomials being multiplied, and they are special because there is a specific formula for them. Perfect square trinomial:(a+b)^2, a^2+2ab+b^2. Difference of squares: (a+b)(a-b), a^2-b^2
So this is an algebra question, where you have have to setup the equation. Let t represent the number of hours.
36 + 8.80t < 115.20 we can then setup the equation like this to solve for the max hours.
36 + 8.80t= 115.20
Now solve
8.80t = 115.2-36
8.80t= 79.2
t = 9
so t < 9
