Please solve both of these with how you solved them.

Step-by-step explanation:

4x - 3 = -2x + 9

    6x = 12

      x = 2

      y = 4(2) - 3

      y = 5

(2, 5)

5x/4 - 2 = -x/4 + 19

    6x/4 = 21

          x = 14

          y = 5(14)/4 - 2

          y = 15.5

(14, 15.5)

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
