Answer: (1,5)

Step-by-step explanation:

1. To solve this, use the midpoint formula:

$(\frac{x1+x2}{2}, \frac{y1+y2}{2})$

2. Insert your values into the equation to get your answer

$(\frac{-3+5}{2}, \frac{5+5}{2})$

3. Simplify the formula

(1, 5)

4. The midpoint is (1, 5)

What TWO steps do you take to solve the following equation: 5x - 3 = 12

hichkok12 [17]

Answer:

First add 3 to each side

Then divide each side by 5

Step-by-step explanation:

5x - 3 = 12

First add 3 to each side

5x-3+3 = 12+3

5x = 15

Then divide each side by 5

5x/5 = 15/5

x = 3

Find the constant of variation k for the inverse variation. Then write an equation for the inverse variation. Y=4.5 when x = 3

Nookie1986 [14]

$\bf \qquad \qquad \textit{inverse proportional variation}\\\\
\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad y=\cfrac{k}{x}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
\textit{we also know that }
\begin{cases}
y=4.5\\
x=3
\end{cases}\implies 4.5=\cfrac{k}{3}\implies 4.5(3)=k
\\\\\\
13.5=k\qquad therefore\qquad \boxed{y=\cfrac{13.5}{x}}$
