Find the solution of this system of equations.
Elenna [48]
<span>-4x + y = -25        y = 4x - 25

-6x - 6y = 0            </span>
 
-6x - 6(4x - 25) = 0
-6x - 24x + 150 = 0
-30x + 150 = 0
-30x = -150
x = 5

y = 4(5) - 25
y = 20 - 25
y = -5

(5, -5)

Find the area of this trapezoid.
timurjin [86]

Answer:

7.5 units squared

Step-by-step explanation:

Equation for solving the area is A = 1/2h(b1 + b2).

The bases here have a length of 4 and 1, so we add them together. The height is 3, so our equation is 1/2 * 3(5) = 7.5
