Answer: Option A

Step-by-step explanation:

To get from A to A', what is done?

A is at the point (2,6) and A' is at the point (2,-1)

The x value of the two points stayed constant (didn't change) meaning that options C and D are invalid (because those two are transformations to the x-value)

Now let us take a look at options A and B which both concern the y value

The y-value of A is 6 and A' is -1

To get from 6 to -1, do you

a) subtract 7

or b) = multiply by -1

Let us test it out:

a) 6 - 7 = -1 (yes, it equals -1)

b) 6 * -1 = -6 (no, it does not equal the intended value of -1)

Thus correct choice is A, we subtract 7

How do you find a rectangular prisms height with length and width given

Naily [24]

If you are given the volume then you can solve
v=volume
h=height
l=legnth
w=width

hlw means h times l times w
v=hlw
so to find height divide both sdie sby lw
v/lw=hlw/lw
v/(lw)=h
so just divide volume by the quantity lengh times width
if you were given the volume

8 necklace have 864 beads in all how many beads will 15 such necklace have?

Elza [17]

864/8 gives you 108. There are 108 beads on each necklace. So for 15 necklaces, multiply 108 and 15. There are 1,620 beads in 15 necklaces.

What type of number can be written as an a fraction a/b where a and b are Integres and b is not equal to zero?

faltersainse [42]

Answer:

Integers, Terminating Decimals, Recurring Decimals, Proper and Improper Fractions.

Step-by-step explanation:

The following subset of the real number system can be written in the form $\dfrac{a}{b}$ , b≠0.

Integers(ℤ): These are positive and negative whole numbers. For example, 5 can be written as $\dfrac{5}{1}$

Terminating Decimals: These are fractions that when converted to decimal numbers have an end.

e.g. $\dfrac{5}{2}=2.5$

Recurring Decimals: These are fractions that when converted to decimal numbers do not have an end.

e.g. $\dfrac{8}{11}=0.727272...=0.\overline{72}$

Proper Fractions: These are fractions of the form $\dfrac{a}{b}$ where a<b. An examples is $\dfrac{4}{5}$

Improper Fractions: These are fractions of the form $\dfrac{a}{b}$ where a>b. An examples is $\dfrac{5}{4}$
