Answer:
<u>14762 ft³</u>
Step-by-step explanation:
<u>Volume of top prism</u>
- V = 61 x 8 x (19 - 3)
- V = 488 x 16
- V = <u>7808 ft³</u>
<u />
<u>Volume of bottom prism</u>
- V = 61 x 38 x 3
- V = 183 x 38
- V = <u>6954 ft³</u>
<u />
Total volume = Volume (top) + Volume (bottom)
- 7808 + 6954
- <u>14762 ft³</u>
Answer:
Therefore, the only ordered pair that is a valid solution is B)
Step-by-step explanation:
In order for a pair to be a solution of a function, the equation must be valid when said point is used in it. We will check for each point:
A) (-1, 4)
f(x) = 3*x - 1
4 = 3*(-1) - 1
4 = -3 -1
4 = -4 (invalid)
B) (-1, -3)
f(x) = 3*x - 1
-3 = 3*(-1) - 1
-3 = -3 -1
-3 = -4
C) (-1, -4)
f(x) = 3*x - 1
-4 = 3*(-1) - 1
-4 = -3 -1
-4 = -4 (valid)
D) (-1, 2)
f(x) = 3*x - 1
-1 = 3*(2) - 1
-1 = 6 -1
-1 = 5 (invalid)
Answer:
b
Step-by-step explanation:
5x +3(x-1) -10x -2x -3
5x +3x -3 -10x -2x -3
8x -3 -10x -2x -3
-2x -3 -2x -3
-4x -6
if this equation is equal to zero then x = -3/2
-1x=12
Divide -1 on both sides...
The 1’s cancel out and 12 divided by -1 equals...
x= -12
