50 because 80+50+x=180 (inside triangle) x=130 180-130= 50 (angle outside triangle)
Death lake would be the answer
F(x) = -2(x + 3)^2 - 1
vertex = (-3, -1)
domain is all real number values of x and
range is all real numbers values of y less than or equal to -1.
42.1% of 375.4.....turn percent to decimal...." of " means multiply
0.421(375.4) = 158.0434.....so it would be B. 158.04
Answer:
y=1
Step-by-step explanation:
you can use those points to find the slope
use the equation
then plug in the numbers
so (1-1)/(-8-7) = 0/15 so the slope is zero meaning it is a horizontal line which we can tell logically because the y coordinates of both points are 1.
so if you plug those numbers into the formula y=mx+b where m is slope and b is the y intercept then
you get y=0*x+1
then 0*x is just zero and it goes away so the equation for this line is y=1
Hope this helps! :)
