Question

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

Answer 1

Answer:

y=-47

Step-by-step explanation:

we know that

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

$m=(\frac{x_1+x_2}{2})$

we have

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

substitute the given values

$-7=(\frac{y+33}{2})$

solve for y

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