It can consist of translations (slides), reflections (flips), and rotations (turns).

I would say a reflection, then slide right, then slide down.

Given that f(x) = x2 – 3x – 28 and g(x) = x - 7, find

gregori [183]

Answer:

$(f-g)(x)=x^2-4x-21$

Step-by-step explanation:

We are given the two functions:

$f(x)=x^2-3x-28\text{ and } g(x)=x-7$

And we want to find:

$(f-g)(x)$

This is equivalent to:

$=f(x)-g(x)$

Substitute:

$=(x^2-3x-28)-(x-7)$

Distribute:

$=x^2-3x-28-x+7$

Rearrange:

$=(x^2)+(-3x-x)+(-28+7)$

Hence:

$(f-g)(x)=x^2-4x-21$

What number is to 100 as 4 is to 78

vitfil [10]

Hello,

4 is to 78 as x is to 100, we write it as a ratio:

$\frac{4}{78}= \frac{x}{100} \\ \\ x= \frac{100*4}{78} \\ \\ \boxed{x= \frac{200}{39}=5.13}$

rate of change as in the gradient??
if yes then the formula would be rise over run, so y over x, therefore 1/3
