Answer:
D) 
Step-by-step explanation:
You have to use the laws of exponents to solve this:
Power of a Power: 
. In this case, 
, all of the numbers in the parenthesis need to be multiplied to the power of 3: 
.
Quotient of Powers: 
. In this case, 
, all of the exponents need to be subtracted (but the 4³ (64) and 8 need to be divided): 
.
Use the Power of a Power again for the expression at the right: 
. You get: 
. Keep the subtraction/negative sign where it is.
Together, you get: .
Hope it helps!
Answer:
B
Step-by-step explanation:
You only need to look at the comparison symbol (≤) to determine the correct graph. It tells you the shading is below the boundary line, and the boundary line is included in the solution region (a solid line).
The shading is below the line because y-values are less than (or equal to) values on the line.
Choice B matches the attached graph.

Step-by-step explanation:
For the -5+5y=40 the answers is y=9
And for 4x+3y=24 is x=-3/4y +6
Answer:
the answer is 20
Step-by-step explanation:
The answer is 20. The rule of math, for this math problem, is that you do the multiplication first and then solve. Order of operations is "PEMDAS," which explained is by following these rules: Parentheses First.
