<h3>Answer: Choice A</h3>

y axis, x axis, y axis, x axis

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

Explanation:

Reflecting an object over the y axis twice will have it end up in its starting position. The same can be said for the x axis as well. It doesn't matter that the x axis reflections aren't grouped next to each other, nor the y. So in a sense, two x axis reflections undo each other, so do the y axis reflections, and we end up with the same image as shown in the diagram.

Answer:

D y=2/3 x +1

y= -3/2 x+2

Step-by-step explanation:

Perpendicular lines have slopes that multiply to -1

The equations are written in slope intercept form

y = mx+b where m is the slope

A 1/5* 5 = 1 not perpendicular

B 2/3 * 3/2 = 1 not perpendicular

C -1/5 * -5 = 1 not perpendicular

D 2/3 * - 3/2 = -1 perpendicular

What property should be initially applied to simplify the expression (4a + 4b) + (2b - c) + 5c?

Jobisdone [24]

Step-by-step explanation:

There is nothing special in the given expression.

first of all we can arrange the likes terms together to reduce the expression, and there is no need of parenthesis so we can write

4a+4b+2b-c+5c

=4a+4b+4c

taking 4 common we get

4(a+b+c)

$f(x)=13|x-5|-6$ is the equation represented by all the operations.

<u>Step-by-step explanation:</u>

The given function is

$f(x)=|x|$

It is vertically compressed by a factor of 13 then the function becomes,

$f(x)=13|x|$

It shifted down 6 units, then the function becomes,

$\mathbf{f}(\mathbf{x})=\mathbf{1 3}|\boldsymbol{x}|-\boldsymbol{6}$

It shifted right by 5 units then the function becomes,

$f(x)=13|x-5|-6$

Thus the resultant equation thus obtained is $f(x)=13|x-5|-6$

The width of a rectangle is 7 meters greater than its length. If the area of the rectangle is 170 square meters, write the quadr

Lostsunrise [7]

Since x represents the length (in meters), the width, which is 7 meters greater, is x +7. The product of these dimensions is the area (in square meters):
x(x +7) = 170
In standard form, the quadratic is ...
x² +7x -170 = 0
