Answer:
17/3
Step-by-step explanation:
Perpendicular means that the slopes are negartive inverses, aka
slope1 times slope2=-1
y=mx+b
slope=m
y=-1/2x-2
slope=-1/2
we need to find negative inverse
-1/2 times what=-1
answer is 2
y=2x+b
input the point (2,-2) to find b
(x,y)
(2,-2)
-2=2(2)+b
-2=4+b
minus 4 from both sides
-6=b
y=2x-6
the equtaion is y=2x-6
The object is to get everything except for "h" on one side of the equation.
The equation says that everything on the right side is being multiplied by 1/2.
What do we have to multiply times 1/2 to get 1? The answer is 2.
So multiply both sides by 2 to get rid of the fraction.
2A = (a+b)h
Now we are multiplying h times (a+b) so to get rid of (a+b) we have to divide both sides by that term.
(a+b)/(a+b) is 1
So you are left with: 2A/(a+b) = h
Done!
Answer:
y = (-5/7) x + 1
Explanation:
The slope-intercept form of the line has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept
The given is:
5x + 7y = 7
To put this in slope-intercept form, we will need to isolate the y as follows:
5x + 7y = 7
7y = -5x + 7
y = (-5/7) x + (7/7)
y = (-5/7) x + 1
where:
m is the slope = -5/7
c is the y-intercept = 1
Hope this helps :)
