Answer:
Step-by-step explanation:
the minimum of f is for x = 1 and f(1)=0
f is decreasing for x<=1 and increasing for x>=1
so the domain is 
x>=1 so x is positive and we can take the square root
so 
8+(-10) is like 10-8 except backwards so how i do some problems is like that and then add a negative sign; so say if i were doing 8+(-10), i would do 10-8 which equals 2 and then since 10 is bigger than 8 and it’s a negative number, i would put -2 as my answer
Answer:
<1 = 33 degrees
<2 = 33 degrees
<3 = 114 degrees
Step-by-step explanation:
<1 and <2 = x
<3 = 3x+15
<1 + <2 + <3 = 180 degree
x + x + 3x + 15 = 180
5x = 180 - 15
x = 165/5
x = 33
<3 = 3(33)+15
= 114 degrees
The main thing is rise/run. y=mx+b that is the formula for slope
