Corey calculated the midpoint of AB with A (-3.5) and a B (1,7). What is corry's error?

Step-by-step explanation:

He,smixing x and y values and averaging them. You add x of one point and add to the x value of the second point. Then divide by 2. Do the same with the y values.

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

a negative exponent is translated as follows:

so, we have
