Answer:
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
In which m is the slope and b is the y-intercept.
Perpendicular lines:
When two lines are perpendicular, the multiplication of their slopes is -1.
Perpendicular to y=1/8x+2
This line has slope 
So, for the line we want to find the equation, we have that:
So
Find the equation of the line through point (1,−5)
This means that when 
. We use this to find b. So:
The equation of the line is:
Answer:
360 cm^2
Step-by-step explanation:
length x width x height
6 x 6 x 10
Answer:
2x-1=x+1
2x-x=x
1+1=2
x=2
Knowing x's value, we substitute it with the equations
y=x+1
y=2+1
or y=2x-1
y=2(2)-1
y=4-1
y=3
(2,3) are your coordinates :D
Answer:
180
Step-by-step explanation:
The difference between 68 and 23 is 45. The company charging 23$ has to be 45$ more for the amount of hours. When you multiply 180 by .4 you get 72, and when you multiply 180 by .65 you get 117. The difference is 45.
Sorry that I didn't show my work, I don't really know how to do this other than plugging in random numbers and 180 fits so...
Hope this helps!
6/8 = 0.75
0.75 x 100 = 75%
