9x^2-12x+3

Answer:

3(x-1)(3x-1)

Multiply the two brackets together

Check answer:

Answer:

x=1 or x=1/2

Step-by-step explanation:

9x^2 - 12x +3

9x^2 -(9+3)x+3

9x^2-9x-3x+3

9x(x-1)-3(x-1)

(x-1)(9x-3)

so,

either x-1=0

x=1

or

9x-3=0

9x=3

x=3/9

x=1/2

4. Determine whether f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.
Ierofanga [76]

Answer:

YES! we conclude that f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.

Step-by-step explanation:

Given

Given that the function f(x) and g(x) are inverse functions.

f\left(x\right)\:=\:\frac{1}{3}x\:+\:5

g(x) = 3x - 15

To determine

Let us determine whether f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.

<u>Determining the inverse function of f(x) </u>

A function g is the inverse function of f if for y = f(x), x = g(y)

y=\frac{1}{3}x+5

Replace x with y

x=\frac{1}{3}y+5

Solve for y

y=3x-15

Therefore,

YES! we conclude that f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.

Find the distance between the points given. (-3, -6) and (3, 2)
vlada-n [284]

Answer:

10 units

Step-by-step explanation:

Moving from (-3, -6) to (3, 2), x increases by 6.  Draw a triangle and use this 6 as the length of the base.  y increases by 8.  Label the height of the triangle with this 8.  Then find the hypotenuse (which is also the desired distance) by using the Pythagorean Theorem:

6^2 + 8^2 = d^2, where d is that distance:

36 + 64 = 100 = d^2, and so d = 10.  The distance in question is 10 units.
