Answer:
y = 3x - 5
Step-by-step explanation:
y = mx + b
m (slope) = 3/1 or 3
b (y-intercept) = -5
y = 3x - 5
Substitute 2x + 11 where you see y in the second equation and solve for x.
3x + 4(2x + 11) = -11
3x + 8x + 44 = -11
11x + 44 = -11
11x = -55
x = -5
Now, substitute -5 where you see x in the first equation and solve for y.
y = 2(-5) + 11
y = -10 + 11
y = 1
The answers are x = -5 and y = 1.
Answer:
2160 in^3
Step-by-step explanation:
V = 
h = 15 in.
l = 12 in.
w = 12 in.
V = 
You have a rectangle that is 8 ft by 10 ft
Area = 8 * 10 = 80 square feet.
Then there is a triangle 8 ft high with a base of 4 feet.
Area = /2 x 8 x 4 = 16 square feet.
Add together for total area:
80 + 16 = 96 square feet.
