Answer:

(-1,-1)

Step-by-step explanation:

Midpoint equation: (\frac{x_2+x_1}{2}, \frac{y_2+y_1}{2})

= (\frac{-5/2+1/2}{2},\frac{-1/2-3/2}{2} )

= (\frac{-2}{2},\frac{-2}{2})

=(-1,-1)

Use the formula and plug it in :)

We are asked to find 7 is what percent to 30.

We will use proportions to solve our given problem.      

Let us assume that 7 is n% of 30. So we can set a proportion as:

\frac{n}{100}=\frac{7}{30}

Let us solve for n.

\frac{n}{100}\cdot 100=\frac{7}{30}\cdot 100

n=\frac{7}{3}\cdot 10

n=\frac{70}{3}

n=23.333

Therefore, 7 is 23.333\% of 30.

Answer:

C. 0 6 10

Step-by-Step-Explanation:

the number on the left of the indicated operation is the original set

the number '2' next to R shows that you need to multiply certain numbers by 2

the subscript on the R's shows which row the multiplication needs to be done on...

so in this case, leave the second row alone: 1  3  4

but multiply the first row by 2: 0  6  10
