Answer:

D.0

Step-by-step explanation:

−3+8x−5=−8

−3+8x+−5=−8

(8x)+(−3+−5)=−8

8x+−8=−8

8x−8=−8

Step 2: Add 8 to both sides.

8x−8+8=−8+8

8x=0

Step 3: Divide both sides by 8.

8x/8=0/8

x=0

Answer:

x=0

Step-by-step explanation:

-3 + 8x - 5 = -8

Combine like terms

-8+8x = -8

Add 8 to each side

-8+8+8x = -8+8

8x = 0

Divide each side by 8

8x/8 = 0/8

x =0

Answer:

A reflection about y=x

Step-by-step explanation:

The 4 transformations are

Translation
Rotation
Reflection
Dilation

Let eliminate which ones won't work.

A translation wouldn't flip the triangle in a different direction after translating it so we won't translate it.

A dilation changes the length for the triangle but the triangles are congruent so we won't dilate it.

A rotation about the orgin wouldn't work nor a specific point so a rotation isnt going to work.

A reflection will work so what will we reflect about.

Some corresponding coordinates are
5,6 and 7,6
1,6 and 7,2
3,8 and 9,4.

A reflection makes a reflected point equidistant from the line of reflection and their original point is equidistant from line of reflection.

So let find the midpoint of all the points and find a line where all of them are on.

The midpoint respectively are

Let find the line that includes both these points.

$\frac{6 - 4}{6 - 4} = \frac{2}{2} = 1$

So this means our slope is x. The y value corresponds with the x value so the answer is

$y = x$

So the answer is

"A reflection about y=x

Which table does not show a direct variation?

stiv31 [10]

Answer:

Table J

Step-by-step explanation:

A direct variation is a simple relationship between x and y.

When you are looking for the direct relationship you should use the formula for it y=kx, or you could just divide y over x ( $\frac{y}{x}$ ).

Analysing Table F:

The relationship between x and y is 4.

$\frac{-8}{-1}=4\\\\\frac{-4}{-1}=4\\\\\frac{0}{0}= origin\\\\\frac{4}{1}=4$

The origin is fine and doesn't ruin the relationship.

Analysing Table G:

The relationship between x and y is 5.

$\frac{5}{1}=5\\\\\frac{10}{2}=5\\\\\frac{15}{3}=5\\\\\frac{20}{4}=5$

Analysing Table H:

The relationship between x and y is $\frac{1}{3}$ .

$\frac{0}{0}=origin\\\\\frac{1}{3}=\frac{1}{3}\\\\\frac{2}{6}=\frac{1}{3}\\\\\frac{3}{9}=\frac{1}{3}$

Like I said before the origin doesn't ruin the relationship so it's fine.

Analysing Table J:

This one doesn't have a direct relationship between x and y.

$\frac{1}{1}=1\\\\\frac{4}{2}=2\\\\\frac{9}{3}=3\\\\\frac{16}{4}=4$

Mario spent $23.85 at the bookstore on one book and some magizines. The book cost $12.60 and the magizines cost $2.25 each. How

alexandr1967 [171]

Answer:

Mario bought five books.

Step-by-step explanation:

If Mario bought n magazines, then n is the solution of

23.85 = 12.60 + n*2.25

23.85 - 12.60 = n*2.25

11.25 = n*2.25

n = 11.25/2.25

n = 5
