Answer:

It should be the top left graph where there is point (1,1) and (-1, -1) y = 1/x

Step-by-step explanation:

from the original graph, I see:

f(x) = 2/x because f(2) = 1 = 2/2

f(1/4)= 2/(1/4) = 2

...

so then f(2x) compresses f(x) horizontally by a factor of 2

so f(2x) = 2/(2x) = 1/x

Step-by-step explanation:

Let us say, Olivia's age is x.

Now as the question says, we will get this equation.

$( \frac{1}{3} x ) + 12= 2x - 3$

Multiply both sides by 3.

$x + 36 = 6x - 9$

Collect like terms.

$x - 6x = - 9 - 36$

Calculate.

$- 5x = - 45$

Divide both sides of the equation by -5.

$x = 9$

Then, we will get the answer.

I hope it helps.

Answer:

(g o f)(x) = $\sqrt{-510}$ (not simplified)

Step-by-step explanation:

(g o f)(x) = g(f(x))

g(x) = $\sqrt{3x}$ f(x) = $x^{3} + 9x$

g(f(-5)) = g( $(-5)^{3} + 9(-5)$ = $(-125) + (-45)$ = $-170$

g(-170) = $\sqrt{3(-170)}$ = $\sqrt{-510}$

A water tank holds 944 gallons but is leaking at a rate of 5 gallons per week. A second water tank holds 1,180 gallons but is le

podryga [215]

Answer:

Step-by-step explanation:

The equation is

944 - 5x = 1180 - 9x

Notice what is being said. You start with 944 gallons and take off 5 per week

You also start with 1180 gallons and take on 9 per week.

You want to know when the two are equal. The second tank is larger, but it leaks more. That's what's going to bring about equality.

Add 9x to both sides

944 - 5x + 9x = 1180

944 + 4x = 1180

Subtract 944 from both sides.

4x = 1180 - 944

4x = 236

Divide by 4

x = 236/4

x = 59 weeks
