Answer:
Step-by-step explanation:
Given
Points:
Required
Determine the equation of line that is perpendicular to the given points and that pass through 
First, we need to determine the slope, m of FG
Where
--- 
--- 
The question says the line is perpendicular to FG.
Next, we determine the slope (m2) of the perpendicular line using:
The equation of the line is then calculated as:
Where
Multiply through by 2
Add x to both sides
Hence, the line of the equation is
D is the answer.....
Where are the moderators right now for brainly???????
Answer:
x = ± 2
Step-by-step explanation:
given
40 - x² = 0 ( add x² to both sides )
40 = x² or
x² = 40 ( take the square root of both sides )
x = ± 
= ± 
= ± 2
An inverse function will simply reverse the coordinate pairs of the original function. If f(x)=(x,y), f^-(x)=(y,x).
So 18 is H
...
If f(x)=y=3x-4, to find the inverse function, solve for x, and then reverse the labels as seen below...
y=3x-4
y+4=3x
(y+4)/3=x so the inverse function is:
y=(x+4)/3
Part A: W = 10x
Part B: S = 400 + 15y
Part C: 490 = 400 +15y
-400 -400
90 = 15y
6 = y, so he worked a total of 46 hours.
