Answer:
$390
Step-by-step explanation:
First he has $500-$40=$460
So now he has $460+$30=$490
He has $490-$100=$390
Answer: B
Step-by-step explanation:

(3/4) : (2 1/4)p = 0
(3/4) : ((2 + 1/4))•p = 0
1.333333p = 0
p = 0
That line is in point-slope form:

Where 'm' is the slope and (x1, y1) is a point on the line.
Perpendicular lines have opposite slopes. To get the opposite, we take the reciprocal and multiply it by -1.

Reciprocal:

Multiply by -1:

We can plug this slope and the point into point-slope form, and then convert it to slope-intercept form.


Negatives cancel out:

Distribute 1 into the parenthesis:

Subtract 2 to both sides:
