Answer:

\frac{AB}{A''B''}  = \frac{1}{4}

Step-by-step explanation:

Given the information:

  • A'B'C' reflection over x = −1
  • dilation by a scale factor of 4 from the origin

<=> the two triangles are similar to each other, triangles are similar if they have the same shape, but can be different sizes, so  A″B″C″ is 4 time bigger than ABC

=> the relationship between ΔABC and ΔA″B″C″

= \frac{AB}{A''B''}  = \frac{1}{4}

We choose C.

Hope it will find you well.

Find the slope (8,-5) (8,10)​
andreev551 [17]

Finding the slope using two points:

The formula for slope is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case...

y_{2} =10\\y_{1} =-5\\x_{2} =8\\x_{1} =8

^^^Plug these numbers into the formula for slope...

\frac{10-(-5)}{8-8

\frac{15}{0}

Your slope is undefined. This means that you line is vertical

Hope this helped!

Wewaii [24]

Answer:

average = 52, 100 on fourth test

Step-by-step explanation:

average = 75 + 74 + 71 =  156 / 3 = 52

average = 52

b grade = 75 + 74 + 71 + 100 = 320 / 4 = 80

to get a b grade she must get 100 on her fourth test
