Answer:
second option
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x - 9 ( add 9 to both sides
y + 9 = x
Change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then
[tex]f^{-1}[/tex] (x) = x + 9

Answer:
Step-by-step explanation:
9) In parallelogram, adjacent angles are supplementary
14x - 4 + 86 = 180
14x = 180 - 86 + 4
14x = 98
x = 98/14
x = 7
10) In parallelogram, opposite angles are congruent.
6x + 4 = 64
6x = 64 - 4
6x = 60
x = 60/6
x = 10
11) In parallelogram, opposite sides are congruent.
3x + 4 = 2x + 10
3x -2x + 4 = 10
x + 4 = 10
x = 10-4
x = 6

Find the discriminant and determine the number of real roots for each equation. Show steps.
-3p^2 - 2p = 0
Answers
Answer:
discriminant: 4; number of real roots: 2
Step-by-step explanation:
The coefficients a, b and c of this quadratic are {-3, -2, 0}.
Thus, the discriminant b^2 - 4ac is (-2)^2 - 4(-3)(0), or 4.
Because the discriminant is positive, this quadratic has two real, unequal roots.
-3p^2 - 2p can be factored as follows: -p(3p + 2). If we set this expression equal to zero, we can find the roots: {-2/3, 0}

Al and Tom are painting a shed. Working alone, Al can paint the shed in 2 hrs. Together they can paint the shed in 1.5 hours. How long would it take Tom to paint the shed on his own?
Answers
Answer:
6 hours.
Step-by-step explanation:
The formula sort of has to be invented.
Al
rate = 1 shed / 2 hours
Tom
rate = 1 shed / x hours.
Together.
rate = 1 shed / 1.5 hours.
Equation
1 shed / 2 hours + 1 shed / x hours = 1 shed / 1.5 hours.
1/2 + 1/x = 1/1.5 Put the fractions over a common denominator.
(x + 2) / 2x = 1 / 1.5 Cross Multiply
1.5(x + 2) = 2x Remove the Brackets.
1.5x + 3 = 2x Subtract 1.5x from both sides
3 = 2x - 1.5x
3 = 0.5x Multiply both sides by 2
6 = x
It would take Al 6 hours to do the shed on his own.
