Answer:
y=12
Step-by-step explanation:
30,60,90 triangle
8*rad3=8rad3
8rad3/2=4rad3
4rad3*rad3=12
I’m guessing it’s -2x? if so it’s a straight line going past points (0,5) and (2.5,0)
Answer:
y = 4
Step-by-step explanation:
Given that,
RS= 4y+2, ST = 3y+8, and RT = 38
We need to find the value of y.
As,
RT = RS+ST
Put all the values,
38 = 4y+2+3y+8
38-2-8 = 4y+3y
28 = 7y
y = 4
So, the value of y is equal to 4.
The average is given by
fav = f(a) - f(b)/a-b
f(-4) = 11
f(6) = 51
fav = 51 -11/-4 -6 = -4
