Y=(x+9)(x-3)+c
∵(-3,-36)lies on it.
-36=(-3+9)(-3-3)+c
-36=(-6)(-6)+c
-36=36+c
c=-36-36=-72
y=(x-9)(x+3)-72
y=x^2+3x-9x-27-72
y=x^2-6x-99
Answer: The number pi is an irrational number
Step-by-step explanation:
Pi is irrational because it will never end and at the same time doesnt have a pattern in which the numbers repeat. Here are some of the numbers in pi 3.14159265359
Answer:
y = -1/4x + 4
Step-by-step explanation:
(8,2) and (-4, 5)
Slope = (5 - 2)/(-4 - 8)
= 3/-12 = -1/4
Point (8,2)
b = 2 - (- 1/4)(8)
b 2+ 2 = 4
Answer:
65 degrees
Step-by-step explanation:
Since complementary angles are 2 angles that add up to 90 degrees, all you have to do is subtract 25 from 90.
When you do that you get 65.
Example: 90 - 25 = 65
Slope of a line passing though point (x1,y1) nd (x2,y2) is
(y2-y1)/(x2-x1)
we have
(1,-3) and (3,-5)
x1=1
y1=-3
x2=3
y2=-5
slope=(-5-(-3))/(3-1)=(-5+3)/(2)=-2/2=-1
slope=-1
