Question 4 Please help. If circle A is dilated so that it is the same size as circle B, which transformations could be performed

DIA [1.3K]

There are 3 Answers:

Choice A) reflect the dilated circle over the horizontal line through point C.

Choice D) rotate the dilated circle 180 degrees around point C

Choice E) translate the dilated circle to center B

Due to symmetry, rotations and reflections do not change a circle. This is why we are able to rotate around point C so that it looks like a translation has occurred. A similar thing happens with reflections as well.

Graph -5x+2y=-10<br> NEED HELP PLEASE

BARSIC [14]

Answer:

<h3>In the attachment.</h3>

Step-by-step explanation:

It's the equation of a linear function in a standard form.

Convert to a slope-intercept form y = mx + b:

-5x + 2y = -10 <em>add 5x to both sides</em>

2y = 5x - 10 <em>divide both sides by 2</em>

y = 2.5x - 5

To draw a graph we need only two points.

We choose two arbitrary values of x. Put them to the equation and calculate the values of y:

for x = 0

y = 2.5(0) - 5 = 0 - 5 = -5 → (0, -5)

for x = 2

y = 2.5(2) - 5 = 5 - 5 = 0 → (2, 0)

Plot a straight line through given points.
