Answer:
A
Step-by-step explanation:
In this question only values of x are changed, so graph is shifted 7 units to the left
Answer:
3x³ - 8x² - 7x + 12
Step-by-step explanation:
We multiply these terms, (so expand the brackets). Referring to the diagram attached, we multiply the first terms, outer terms, inner terms, and last terms.
Let's first look at the first two (we will do something about the third brackets later):
(3x+4)(x-1)
Firsts:
3x²
Outer:
-3x
Inner:
4x
Last:
-4
Now we combine:
3x² - 3x + 4x - 4
= 3x² + x - 4
So from the whole equation, we now have this:
(3x² + x - 4)(x - 3)
We do a similar thing here.
3x³ - 9x² + x² - 3x - 4x + 12
Simplify:
3x³ - 8x² - 7x + 12
The solution of the inequality is -8 ≥ b, and the correct graph is the one in option D.
"number line with a closed circle plotted at negative eight and arrow pointing left."

How to solve the inequality?</h3>
Here we have the inequality:
-0.8*b + 2.3 ≥ 8.7
And we want to solve this, to do so, we need to isolate the variable b in one of the sides of the inequality.
-0.8*b + 2.3 ≥ 8.7
2.3 - 8.7 ≥ 0.8*b
-6.4 ≥ 0.8*b
-6.4/0.8 ≥ b
-8 ≥ b
So the solution is the set of all numbers equal to or smaller than -8, then the correct graph will be the one described by D.

8. length is 4 feet
9. width is 8 inches
20. this one could be l=6 and w=8 or l=4 and w=12 because I don't know which side of the rectangle her garage is
I would go with none of the above because it looks like 45 degrees to me
