Answer:
$55
Step-by-step explanation:
I am not good at explaining, but, 10% of 50 is 5.
Marking up means the price goes up.
So if 10% of 50 is 5.
50 + 5 = new price
50 with a mark up of 10% = 55
Answer: 
Step-by-step explanation:
- The equation of the line in point-slope form is:

Where m is the slope and
is a point of the line.
- The equation of the line
is written is slope-intercept form, where the slope is
.
- By definition, when two lines are perpendicular to each other, the slopes are the negative reciprocals. Therefore, the slope of the perpendicular line must be -3.
- Substitute the point P and the slope -3 into the equation in point-slope form, therefore, you obtain:

Answer:
x= -5.1
Step-by-step explanation:
The solution to f(x) = g(x) is where to two graphs intersect
The graphs meet at
about x=2 and x = -5
The best answer listed is x = -5.1
