Perpendicular lines will have negative reciprocal slopes
B. y = -4x+ 5 and y = 1/4x + 4
D. y = x + 4 and y = -x + 4
E. y = -3 and x = -3
Answer:
slope = 3
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (- 3, - 4)
m =
=
= 3
Answer:
150 is the answer
Step-by-step explanation:
5 x 5 = 25
25 x 6 = 150.
So, the count went down from 850 to 500, or 350 units.
if we take the 850 to be the 100%, what is 350 in percentage off of it?

solve for "x".
Answer:
Mary removed the dollar sign from (X.)
We know this because $4.00x$5.00=$20.00 so that’s correct and we know that $12.50x $4.00=$50.00. So, our only error here is that there is no dollar sign in our (X) numbers. So that is Mary’s mistake. We can correct it by simply adding a dollar sign to 20 to make $20.00 and adding another dollar sign to 50 to make $50.00
Step-by-step explanation:
