(8j3 - 5j2 - 5) - (6j3 - 12j2 + 8j - 7) =
(8j3 - 6j3) - (5j2 - 12j2) - 8j - (5-7) =
2j3 - (-7j2) - 8j - (-2) =
2j3 + 7j2 - 8j + 2
The correct answer is D. 2j3 + 7j2 - 8j + 2
· Perpendicular lines have slopes that are opposite reciprocals of each other
· Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept
If the slope of the first line is 3, the slope of the second line is -1/3. Since the lines intersect at the origin, neither of them have a y-intercept.
Answer:
C) y = -1/3x
575 - 455 = $120 (amount of commissions he'll have to earn.
To make $120 in commissions, his sales would have to be $120/.03 =
$4,000.00
There is only one solution
Let losses = X
They won 13 more than 3 times as many so wins = 3X +13
Now you have wins + loses = total games:
X +3X + 13= 109
Combine like terms:
4x + 13 = 109
Subtract 13 from each side:
4x = 96
Divide each side by 4:
x = 96 / 4
X = 24
Wins = 3X +13
3(24) +13 = 72+13 = 85
Wins = 85 games
Losses = 24 games
