Answer:
x = 50
Step-by-step explanation:
SU is a midline segment and is one half the measure of VW, thus
VW = 2SU , that is
x - 46 = 2(x - 48) ← distribute
x - 46 = 2x - 96 ( subtract x from both sides )
- 46 = x - 96 ( add 96 to both sides )
50 = x
The diameter is about 1,275.4 because D=C/pi so 4007\pi=1275.4
I believe your interval is [-2,2]: all numbers between -2 and +2.
Then the ave. r. of c. on this interval is:
f(2) - f(-2) 4^2 + 2 - {4^(-2) + 2}
------------- = ------------------------------
2 - (-2) 4
16 - (1/16) 15 15/16
= --------------------- = --------------- = 3.98 or 255/64
4 4
Answer:
3
Step-by-step explanation:
The whole goal is to isolate the variable.
3x-1=8
1+3x-1=8+1 first add 1 to both sides of the equation to cancel out the -1
3x=9 now just divide 3 to both sides of the equation because the opposite of multiplication is division. So dividing 3 on both sides cancels out the 3 to isolate the x
3x/3=9/3
x=3
