write an equation in slope intercept form for the line that is perpendicular to y=-1/4x+2 and passes through the points (-4,3)
PilotLPTM [1.2K]
For lines to be perpendicular their slopes must be negative reciprocals of one another, mathematically:

m1*m2=-1, and in this case:

-m/4=-1

-m=-4

m=4, so the slope of the perpendicular line is 4 so we have thus far:

y=4x+b, using point (-4,3) we can solve for the y-intercept, "b"

3=4(-4)+b

3=-16+b

19=b, so our line is:

y=4x+19

A farm had 480 acres more wheat than corn. After the farmers collected 80% of the wheat and 25% of the corn, the area of the whe
Sergio [31]
The area covered by corn is x
The area covered by wheat is (x+480)
After 80% of wheat was collected, the new area was:
20/10(x+480)
=1/5(x+480)
After 25% of the corn was collected, the new area was:
75/100x
=3/4x
New area equation will be:
(3/4)x=1/5(x+480)+300
(3/4x)=(1/5)x+96+300
solving for x we get:
11/20x=396
x=720
thus the original area of corn was 720 acres
Original area of wheat was 720+480=1200 acres
