Find f(x) if it is known that f(x−6)=12x−72.
zheka24 [161]

Answer:

f(x)=12x

Step-by-step explanation

We know that f(x) is our y-coordinate and x is the x-coordinate

Next we should insert x-6 as x in the equation

This is f(x)=12(x-6)-72

But if you look at this that leads to 12x-72 (ignore y-intercept)

That is our first equation  

This means that if you take out -6 from the x

You will get f(x)=12x

(Also do you go to RSM?)

Solve the equation<br> 5.4/12 = z/8
saul85 [17]

Answer:

18/5

Step-by-step explanation:

5.4/12 = 1/8 is equivalent to (5.4)(1/12) = (z/8), or

                                              (54/10)(1/12) = z/8.

The LCD is (10)(8)(12), or 120.

Mult. both sides by 120 yields 54 = 15z.

Dividing both sides by 15, we get z = 54/15 = 18/5 = z

[ Please help! ] Choose the equation that represents the graph below.
Kitty [74]

The line crosses the x -axis at point (9,0) and the y-axis at point (0,6).

If the equation of the line is y=kx+b, then substitute the coordinates of the points into this equation:

1) 0=9k+b;

2) 6=b.

Substitute the second equation into the first:

9k+6=0,\\ \\k=-\dfrac{2}{3}.

The equation of the line is

y=-\dfrac{2}{3}x+6.

Answer: option C
