Question

The midpoint between y and 33 is −7. Find y.

Answer 1

y=-47

Explanation:

we know that

The formula to calculate the midpoint between two points in a number line is given by

`m=((x_1+x_2)/(2))`

we have

`x_1=y\\x_2=33\\m=-7`

substitute the given values

`-7=((y+33)/(2))`

solve for y

`-14=y+33\\y=-14-33\\y=-47`
