Answer:
A = 56 in²
Step-by-step explanation:
the area (A) of a trapezoid is calculated as
A =
h (b₁ + b₂ )
h is the perpendicular height between bases and b₁, b₂ the bases
here h = 7 , b₁ = 10 , b₂ = 6 , then
A =
× 7 × (10 + 6) = 3.5 × 16 = 56 in²
We have the following system of equations:
y = -6x-6
y = x2-5x-6
Matching we have:
x2-5x-6 = -6x-6
Rewriting we have:
x2-5x-6 + 6x + 6 = 0
x2 + x = 0
Rewriting:
x (x + 1) = 0
The solutions are:
x = 0
x = -1
For x = 0
y = -6 (0) -6 = 0-6 = -6
y = -6
For x = -1
y = -6 (-1) -6 = 6-6 = 0
y = 0
The solutions are:
(x, y) = (0, -6)
(x, y) = (- 1, 0)
Answer:
The solutions of the system are:
(-1, 0) and (0, -6)
