2(x+3)=x-4 please help me <3

1 answer:

4 0

2(x + 3) = x - 4

distribute

2x + 6 = x - 4

either subtract 6 from both sides or add 4. i will be subtracting 6.

2x = x - 10

subtract x from both sides

x = -10

If g is the inverse of the function f(x) = sqrt(x - 6) - 10 , which of the following is g?

iren2701 [21]

Answer:

g(x) = x² + 20x + 106

Step-by-step explanation:

Given:

$f(x) =\sqrt{x-6}-10$

If g(x) is the inverse of f(x), find it.

Swap x with g(x) and f(x) with x:

$x =\sqrt{g(x)-6}-10$

Solve for g(x):

$x + 10 = \sqrt{g(x)-6}$
$(x+10)^2=g(x)-6$
$g(x) = x^2+20x + 100+6$
$g(x) = x^2+20x + 106$

3) 5 fl. oz. of a 2% alcohol solution was mixed with 11 fl.

dangina [55]

Answer:

The concentration of the new mixture is 46%

Step-by-step explanation:

The first solution of 5 fl. oz. is concentrated at 2% alcohol. The amount of alcohol in the solution is:

5*2/100=0.1 fl. oz.

The second solution of 11 fl. oz. is 66% alcohol. The amount of alcohol in the solution is:

11*66/100=7.26 fl. oz.

The total alcohol in the mixture is

0.1 + 6.6 = 7.36 fl. oz.

The total amount of the mixture is:

5 + 11 = 16 fl.oz.

The concentration of the new mixture is:

7.36 / 16 * 100 = 46%

The concentration of the new mixture is 46%
