Segments PX and QY are altitudes of acute triangle PQR, and Z is the midpoint of segment PQ. Prove that triangle XYZ is isosceles. (Please provide a diagram in addition to the actual proof)

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
