Answer:
1. -1/28
2. -4
3.A) The attendance increased by an average of 25 people per game from game 2 to game 5.
4. -.125
Step-by-step explanation:
To find the rate of change, we use the formula
f(x2) - f(x1)
--------------
x2-x1
1.
f(x) = -(x) ^ 1/3
f(64) = -(64) ^ 1/3 = -4
f(8) =- (8)^1/3 = -2
f(64) - f(8) -4--2 -4+2 -2 -1
-------------- = --------- = ------------- = ----------- = ------
64 - 8 56 56 56 28
2.
f(2) = 9
f(-2) = 25
f(x2) - f(x1) f(2) - f(-2) 9-25 -16 -16
-------------- =----------- = ----------------- = ---------- = ----------- = -4
x2-x1 2--2 2+2 4 4
3.
f(5) = 755
f(2) = 680
f(x2) - f(x1) f(5) - f(2) 755-680 75
-------------- = ---------- = -------------- = ---------- = 25
x2-x1 5-2 3 3
A) The attendance increased by an average of 25 people per game from game 2 to game 5.
4.
f(-1) = -.25
f(1) = -.5
f(x2) - f(x1) f(1) - f(-1) -.5 --.25 -.5+.25 -.25
-------------- = ---------- = -------------- = ---------- = --------- = -.125

Answer:
10\7
Step-by-step explanation:
7x-4=6
7x=6+4
7x=10
7x\7=10\7
x=10\7
The given endpoints are A (-1, 2) and B (7, 8).
Let the coordinates of P be (x,y)
Because AP:PB = 1:3, therefore
Cross multiply.
3(x+1) = 7 - x
3x + 3 = 7 - x
4x = 4
x = 1
Also,
Cross multiply.
3(y - 2) = 8 - y
3y - 6 = 8 - y
4y = 14
y = 7/2
Answer:
The coordinates of P are (1, 7/2)

Answer:
x = 38
Step-by-step explanation:
RT is a midsegment and is one half the measure of QU, thus
QU = 2RT, that is
x - 6 = 2(x - 22) ← distribute
x - 6 = 2x - 44 ( subtract x from both sides )
- 6 = x - 44 ( add 44 to both sides )
38 = x
