Answer:
4 beacause when we multiply it will be 8.9523
So anytime we have a slope and want to find the slope of a perpendicular line, we just have to remember a perpendicular line's slope is the negative reciprocal (reciprocal means flip the fraction). So if we had a slope of 3/4, the slope perpendicular to it would be - 4/3.
First we need to find our slope, to do this we take the change in y over the change in x like so:
(15-12)/(4-7) = - 3/4
The slope perpendicular to this is 4/3.
It would be .546% increase per year. You divide 292662.70 by 268000 and get 1.092025 and then divide by 2 for the years and get .546. Hope this helps
Answer:
x=10 x=-4
Step-by-step explanation:
x^2 +6x = 40
subtract 40 from each side
x^2 +6x -40 = 0
what numbers multiply to -40 and add to 6
-10 *4 = -40 -10 +4 = 6
(x-10) (x+4) = 0
using the zero product property
x-10 = 0 x+4 =0
x=10 x=-4
