It's simple, there is a ton
Multiply all the numbers by 2: 20m - 80
or Divide all the numbers by 2: 5m- 20
or Multiply all the numbers by 3: 30m - 120

Answer:

The lower left one.

Step-by-step explanation:

If you expand and rearrange it, you will find out both of its constant cancel out, and leave you with 3w=3w. So w have infinite number of solutions.

Is 8 a unique solution to the equation 3(x-6) =<br><br> 3x/4

ladessa [460]

Answer:

yes

Step-by-step explanation:

3(x - 6) = $\frac{3x}{4}$ ( multiply both sides by 4 to clear the fraction )

12(x - 6) = 3x , distribute left side

12x - 72 = 3x ( subtract 3x from both sides )

9x - 72 = 0 ( add 72 to both sides )

9x = 72 ( divide both sides by 9 )

x = 8

x = 8 is the only solution and is therefore unique

Evaluate the function f(x) at the given numbers (correct to six decimal places). f(x) = x2 − 3x x2 − 9 , x = 3.1, 3.05, 3.01, 3.

Lostsunrise [7]

Answer:

Values of f(x) for different values of x.

Step-by-step explanation:

We are given the following function in the question:

$f(x) = \displaystyle\frac{x^2-3x}{x^2-9}$

We have to find the value of given function at the following x.

x = 3.1, 3.05, 3.01, 3.001, 3.0001, 2.9, 2.95, 2.99, 2.999, 2.9999

$f(x) = \displaystyle\frac{x^2-3x}{x^2-9}\\\\f(3.1) = \frac{(3.1)^2-3(3.1)}{(3.1)^2-9} = 0.508197\\\\f(3.05) = \frac{(3.05)^2-3(3.05)}{(3.05)^2-9} = 0.504132\\\\f(3.01) = \frac{(3.01)^2-3(3.01)}{(3.01)^2-9} = 0.500832\\\\f(3.001) = \frac{(3.001)^2-3(3.001)}{(3.001)^2-9} = 0.500083\\\\f(3.0001) = \frac{(3.0001)^2-3(3.0001)}{(3.0001)^2-9} = 0.500008\\\\f(2.9) = \frac{(2.9)^2-3(2.9)}{(2.9)^2-9} = 0.4915254\\\\f(2.95) = \frac{(2.95)^2-3(2.95)}{(2.95)^2-9} =0.495798\\\\$

$f(2.99) = \displaystyle\frac{(2.99)^2-3(2.99)}{(2.99)^2-9} =0.499165\\\\f(2.999) = \displaystyle\frac{(2.999)^2-3(2.999)}{(2.999)^2-9} = 0.499917\\\\f(2.9999) = \displaystyle\frac{(2.9999)^2-3(2.9999)}{(2.9999)^2-9} =0.499991$
