Answer:

Step-by-step explanation:

2x2x2=8

2x2=4x2=8x2=16x2=32x2=64

64x8=512

2•2•2=8, and (2^6)^2 is (2^6)(2^6), which equals 4,096, so 4,096•8=32,768

Which relation is also a function? A, B, C, or D?

Answers

Answer:

AorD

srry if im wrong its not B because some of them are not compatible

Step-by-step explanation:

Answer: Choice D

===================================================

Explanation:

To have a function, we cannot have repeated x values. Put another way, we can't have any input go to more than one output. Choices A through C are not functions because....

Choice A has x = 10 go to more than one y output.Choice B has x = 2 go to more than one y output. Choice C has x = 4 go to multiple y outputs.

Only choice D has each x value listed one time. We don't have any repeated x values. Any x input leads to exactly one y output. This is why choice D is a function.

The constant of proportionality for this relationship is

Answers

Answer: The constant of proportionality is 1.5

Step-by-step explanation:

The equation for constant of proportionality is y=KX. the K stands for the constant of proportionality and since the constant proportionality is 1.5 you will take 1.5 * x and for example x is 2 so you do 1.5 * 2 and you get 3 and 3 is your y. If you plug in the equation you're saying 3 equals 1.5 * 2 which is right.

Mary is making pillows for her Life Skills class. She bought 2.5 yards of fabric. Her total cost was $15. What was the cost per yard?
$10/yard
$6/yard
$7.50/yard

Answers

Answer:$6/Yard

Step-by-step explanation:

You make it into an algebraic expression, 2.5x=15.

Then, you divide both sides by 2.5

2.5x=15, 2.5x/2.5 =x, 15/2.5=6.

x=6.

x represents the amount of dollars per yard.

$6/yard
I solved by dividing the total cost by the amount of yards of fabric.
