n a number line, the directed line segment from Q to S has endpoints Q at –8 and S at 12. Point R partitions the directed line segment from Q to S in a 4:1 ratio.

Which expression correctly uses the formula to find the location of point R?

((m)/(m+n))(x_(2)-x_(1))+x_(1) <------formula

Answer: Point R will be at the number 8 on the number line.

From -8 to 12, there are 20 numbers. If we want to get a ratio of 4:1, we need to have 5 equal sections.

20 / 5 = 4

Since the ratio is 4:1 to R, we need to move 4 x 4 = 16 spaces from -8.

-8 + 16 = 8

Look for the equation that gives you a value of 8.

Answer:

The answer is B. on edgen

Step-by-step explanation:

B. (4/4+1)(12-(-8)) + (-8)
