Answer:

$9\ years$

Step-by-step explanation:

Let

x------> the number of years

we know that

$(39+x)=4(3+x)$

Solve for x

$39+x=12+4x$

$4x-x=39-12$

$3x=27$

$x=9\ years$

Add 6v to both sides
Subtract 67 from both sides
Divide both sides by -1

NEED HELP EDU!! WILL GIVE BRAINLEIST!<br> which graph of the cube root function f(x)=^3 √x?

Luden [163]

Answer:

C. $f(x)=\sqrt[3]{-x} -1$

Step-by-step explanation:

Consider graph of the parent function (red curve in attached diagram)

$g(x)=\sqrt[3]{x}$

First, multiply it by -1 to get function

$h(x)=-\sqrt[3]{x}$

Then translate the graph of the function h(x) 1 unit down, then you'll get the function

$f(x)=-\sqrt[3]{x} -1\\ \\ \text{or}\\ \\f(x)=\sqrt[3]{-x} -1$

The graph of the function f(x) is represented by the blue curve in attached diagram
