How is this equation properly graphed on the number line?
1 answer:
Given the comopound inequality:
Let's graph the compound inequality.
Here x is greater than -1 but less than or equal to 7.
To graph the inequality, we have:
[tex]-1Since x is greater than -1, plot an open dot on the point -1.Also, x is less than or greater than 7, plot a closed dot on the point 7.
Then draw a straight line connecting both points.
Hence, we have the graph below:

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: .
