The answer is 4+5+6=15.Hope that helps. :)
Answer:
$39.2
Step-by-step explanation:
The sale price will be 20% of $49 subtracted from $49
That’s
20% /100% x $49
0.2 x $49
$9.8
Sale price = $49 - $9.8
= $39.2
The sale price is $39.2
80% × x = 32
.80x = 32
x = 32/.8
x = 40
The perpendicular line will have the x and y coefficients swapped and one of them negated. We can write the desired line as
9(x -6) -3(y -4) = 0
where the coordinates of the point of interest are (6, 4).
Dividing by 3, this is
3(x -6) -(y -4) = 0
3x -y = 14
An equation for the line of interest is ...
3x -y = 14
