Answer:
5x^2-3x-8
Step-by-step explanation:
So you will want this to be simplified.
expanding brackets is a great way of doing this
one you have expanded all brackets u get the answer above
:)
Answer:
It says to Graph y = 1/2x - 4
So equation y = 1/2x - 4
this corresponds to slope intercept form which is y = mx + b
M = slope = rise / run
B = y - intercept
First, start at the origin, (0,0)
Then go down 4, you should now be on the coordinate (0,4)
Now we need to use the slope.
The slope is 1 / 2, this means rise 1, run 2 (in this case 2 to the right because it is positive)
So, start at (0 , 4) and go up 1 unit then 2 to the right, then place a dot, keep repeating until you meet the end of the paper.
Then do the opposite so that you can graph the other side.
Down 1 and 2 to the left.
4½ = 9/2
1 2/5 = 7/5
9/2 * 7/5 = 63/10 = 6 3/10

Answer:
The lines are not perpendicular
Step-by-step explanation:
m1=1/2
m2=2
m1*m2=1/2*2=1
Lines are perpendicular when m1 * m2 = -1 because m1 * m2 = 1 these lines are not perpendicular
