Which formula gives the coordinates of the midpoint of the segment connecting points (a, b) and (c, d)?

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

Valentina is subtracting from . she finds the lcd to be 15y2. what is valentina's next step?

What is the explicit formula for this sequence? -7, -4, -1, 2, a.) an = 8 + (b - 1)3 b.) an = -7 + (n - 1)3 c.) an = 3 + (n -1) (-7) d.) an = -7 + (n - )
