How do I reflect over x=3 ??

This last claim is because x can be thought of as 2+a, where "a" could be negative! Now x needs to go to 2-a, but solveing for "a" in x=2+a gives a=x-2, so the new x is
<span>2-a = 2-(x-2) = 4-x. </span>

<span>(-1,1) => (5,1) </span>
<span>(0,4) => (4,4) </span>
<span>(-3,4) => (7,4)</span>

Which factorization is equivalent to this expression?

grigory [225]

Answer:

$10(3x+7)$

Step-by-step explanation:

we have the expression:

$30x + 70$

To factor this expression we need to indentify the components that are common in both terms.

At first glance there is nothing in common, but we can notice that 30 and 70 are multiples of 10, that is:

$10*3=30\\10*7=70$

so we can substitute this into the expression:

$10*3x+10*7$

and now that we have the common term (the number 10) we can factorize it, that is, take out the common term and include a parentheses:

$10(3x+7)$

The grid shows Figure Q and its image Figure Q′ after a transformation.

Svetach [21]

The transformation of pentagon Q to pentagon Q' is a clockwise rotation of 180° about the origin.

<h3>What is transformation?</h3>

A transformation is a general term for four specific ways to manipulate the shape or position of a point, a line, or a geometric figure.

We have,

Coordinates of a pentagon Q.

(2, 4), (3, 7), (7, 5), (5,4), and (4,2).

Coordinates of pentagon Q'.

(-2, -4), (-3, -7), (-7, -5), (-5,-4), and (-4,-2).

We see that the coordinates of each point of the pentagon Q have changed their position as negative coordinates in pentagon Q'

The coordinates of pentagon Q are in (x, y) which can be assumed to be in the first quadrant of the coordinate plane.

The coordinates of pentagon Q' are in (-x, -y) which is in the 3rd quadrant.

From the first quadrant to 3rd quadrant there is a rotation of 180°.

Thus the transformation of pentagon Q to pentagon Q' is a clockwise rotation of 180° about the origin.
