The center of dilation <em>Y</em> is the point from which the other points expand or

contract away from or towards.

The true statement about A'Y' is; <u>Line A' Y' passes through the center of dilation</u>..

The given parameters are;

The scale factor of dilation of ΔXYZ  = 3

The point of dilation = Point Y

Line YA is vertical (perpendicular) to the base XZ

In a dilation transformation, the extension or compression of the points

are relative to the center of dilation.

Following the dilation, the line AY is extended along AY to A' Y', therefore,

passing through the point <em>Y</em> which is the center of dilation.

<em />

The option that is true is therefore; Line A' Y' passes through the center of

dilation (which is written as <u>line A prime Y prime passes through the center </u>

<u>of dilation</u>)<u>.</u>

It took John 12 hours riding his bike to make the round trip to his uncle's. If he averaged 20 mph out and 30 mph back, how long
notsponge [240]

Answer:

Step-by-step explanation:

Let the time taken by the john to get to his uncle be x.

Let the time taken by the john to get back from his uncle be y.

So,

x+y=12 ------ equation 1

According to the given velocities:

20x=30y

x=3/2y

Put the value x=3/2y in equation 1

3/2y+y =12

3y+2y/2=12

3y+2y=12*2

5y=24

y=24/5

y=4.8h

Now put the value of y in x=3/2y

x=3/2*4.8

x=14.4/2

x=7.2h ....

What is the solution to y-7&gt;3+2y
Alex17521 [72]

Solving:

-7 + y = 3 + 2y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-2y' to each side of the equation.

-7 + y + -2y = 3 + 2y + -2y

Combine like terms: y + -2y = -1y

-7 + -1y = 3 + 2y + -2y

Combine like terms: 2y + -2y = 0

-7 + -1y = 3 + 0

-7 + -1y = 3

Add '7' to each side of the equation.

-7 + 7 + -1y = 3 + 7

Combine like terms: -7 + 7 = 0

0 + -1y = 3 + 7

-1y = 3 + 7

Combine like terms: 3 + 7 = 10

-1y = 10

Divide each side by '-1'.

y = -10

Hope it helps. (:
