Perpendicular lines have slopes that are negative reciprocals.
so first you must find the slope of the line given
the slope formula is
m=(y₂-y₁)/(x₂-x₁)
now you just plug in the coordinate points that you are given
m=(-2-2)/(0-(-3)
m=-4/3
so the slope of the line given is -4/3, the negative reciprocal of this would be 3/4
The slope of the perpendicular line would be 3/4
Answer:
-2(x^2 - x - 1).
Step-by-step explanation:
3x - 2x^2 - x + 2
= 2x - 2x^2 + 2
= -2(x^2 - x - 1)
Answer:
8xº = 90º
6xº = 67.5º
2xº = 22.5º
x = 11.25°
Step-by-step explanation:
The sum of angles in a triangle is 180°
8xº + 6xº + 2xº = 180º
16xº = 180º
x = 11.25º
8xº = 11.25(8) = 90º
6xº = 67.5º
2xº = 22.5º
Hope this helps :)
Answer:
a
Step-by-step explanation:
P = 390,00 + 4000x
450,000 people - (15years x 4000) = 390k in 2010
15 years is the difference between 2010 and 2025
subtract 60k (that is the 15 years multiplied by 4k) from 450k and you get 390k.
Sorry if my explanations suck, I'm not great at explaining my thought process
