On a number line, the directed line segment from Q to S has endpoints Q at a -8 and S at 12 Point R partitions the direct line segment from Q to S in a 4:1 ratio Which expression correctly uses the formula (m/m+n)(x2 - x1) + x1 to find the location of point R?

Step-by-step explanation:

Given

Required

Determine the expression that correctly uses

In

and

Substitute these values in:

The expression becomes:

Solving further:

Hence, R is at 8 on the number line

i think that you should ask google for the answer to that problem because if we don't know it google does
