To find the x int, sub in 0 for y and solve for x
5x - 3y = 30
5x - 3(0) = 30
5x = 30
x = 30/5
x = 6....so the x int is (6,0)
to find the y int, sub in 0 for x and solve for y
5x - 3y = 30
5(0) - 3y = 30
-3y = 30
y = 30/-3
y = -10...so ur y int is (0,-10)
21/10+5/10
Add nominators since denominators are the same.
26/10
Or 2 6/10 as a mixed number.
Answer:
2
Step-by-step explanation:
6*2=12
Answer:
y=1/2x-3
Step-by-step explanation:
First, let's put the line into slope intercept form
2y+4x=12
subtract 4x from both sides
2y=-4x+12
divide by 2
y=-2x+6
the slopes of perpendicular lines are negative and reciprocal. If you multiply the slopes of the lines together, the result is -1. Therefore, to find the slope of the perpendicular line, use this formula:
-2m=-1
divide by -2
m=1/2
so the slope of the perpendicular line is 1/2
here is the new line so far:
y=1/2x+b (b is a place holder)
now, since the line passes through the point (8,1), it means that (8,1) is a solution of the line. So we can substitute it into the equation
1=1/2(8)+b
1=4+b
subtract 4 from both sides
-3=b
so the line is y=1/2x-3
Hope this helps!
