3. IF ON = 5x - 7, LM = 4x +4, NM = x - 7, and OL = 3y – 4, find the values of x and y for which LMNO must
kkurt [141]

Answer:

x = 11 and y = \frac{8}{3}

Step-by-step explanation:

If LMNO is a parallelogram then it's opposite sides will be equal.

So, LM = ON

⇒ 4x + 4 = 5x - 7

⇒ x = 11

Now, MN = OL  

⇒ x - 7 = 3y - 4

⇒ 11 - 7 = 3y - 4 {Since we already have, x = 11}

⇒ y = \frac{8}{3} (Answer)

A system of equations is graphed on the coordinate plane.
8_murik_8 [283]

Answer:

  • The solution is (x, y) = (-2, 0)
  • A graph is attached

Step-by-step explanation:

The graph shows the solution. The first equation has a y-intercept of -4 and a slope of -2, so will go through the point (-2, 0).

The second equation has a y-intercept of +4 and a slope of 2, so will go through the point (-2, 0).

Both equations have the same x-intercept, so that x-intercept is the solution to the system of equations.
