Answer:
c) (-2, 1)
Step-by-step explanation:
3x - 3y = -9
2x + y = -3
2x + y = -3
-2x -2x
y = -2x - 3
3x - 3y = -9
y = -2x - 3
3x - 3(-2x - 3) = -9
3x + 6x + 9 = -9
9x + 9 = -9
- 9 -9
9x = -18
/9 /9
x = -2
y = -2x - 3
y = -2(-2) -3
y = 4 - 3
y = 1
(x, y) --> (-2,1)
Check your answer:
y = -2x - 3
1 = -2(-2) - 3
1 = 4 - 3
1 = 1
This statement is true
Hope this helps!
Answer:
18 inches
Step-by-step explanation:
Volume of a pyramid is:
V = ⅓ Ah
where A is the area of the base, and h is the height of the pyramid.
The base is a rectangle. Area of a rectangle is width times length, so:
V = ⅓ wlh
Plugging in values and solving:
1512 = ⅓ w (21) (12)
w = 18
The width of the base is 18 inches.
