1.)Solve the absolute value equation.
1 answer:
Answer:
B. x = -1 or x = 4 1/3.
Step-by-step explanation:
2|3x -5| -8 =8
2|3x -5| = 16
|3x -5| = 8
The expression in the vertical lines can be positive or negative so we have 2 equations:
3x - 5 = 8 and 3x - 5 = -8
3x - 5 = 8
3x = 13
<u>x = 13/3 or 4 1/3</u>
3x - 5 = -8
3x = -8 + 5 = -3
x = -1.

His total commission was $1560.
P(B) = 0.75.
For independent events, P(A and B) = P(A)*P(B). This gives us
1/8 = 1/6(x)
Divide both sides by 1/6:
1/8 ÷ 1/6 = x
1/8 × 6/1 = x
6/8 = x
3/4 = x
0.75 = x
