The red lines signify congruency. Meaning, if one angle (say <EFD) is 75 and has one red line and <JAB also has one red line, it means it also equals 75.
Just like <GHF is 130 and has two lines, <JBC also has two red lines, so it also equals 130.

F(x) = 8|x| - 5<br> f(-2) =

Anastaziya [24]

Answer:

f(-2) = 11

Step-by-step explanation:

Hello!

We can evaluate y by plugging in -2 for x in the equation.

<h3>Evaluate</h3>

f(x) = 8|x| - 5
f(-2) = 8|-2| - 5
f(-2) = 8(2) - 5 Remember that absolute value turns the number positive
f(-2) = 16 - 5
f(-2) = 11

The evaluated value is 11.

You weren't clear on the equation so I did it both ways. It didn't really matter though because both equations had the same answer. ‍♀️

Help, how would I get my answer for this question?

Maslowich

Answer:

$(-4,32)$

Step-by-step explanation:

Given points are $(-1,-8)$

And given transformation is $D_4$ $r_{x-axis}$

We will start from left to right.

First transformation is reflection about x-axis.

When we reflect about x-axis $(x,y)\ became\ (x,-y)$

So, $(-1,-8)=[-1,-(-8)]=(-1,8)$

Now next transformation is dilation with a factor 4.

If we do dilation with a factor $'k'$ to the point $(x,y)$

New co-ordinates after dilation became $(kx,ky)$

So, $(-1,8)\ became\ (-4,32)$
