Hope this helps!!
Step-by-step explanation:
The first thing we have to do before we can actually do the problem is turn the words into a math equation.
If we use <em>x </em>as our "number," we see that "The sum of a number and 2" can also be written as <em>x</em>+2. The word "Is" almost always means (=), so now we have (<em>x</em>+2) = . The very last part, "6 less than twice that number," means 2<em>x - </em>6.
So, our whole equation is, (<em>x </em>+ 2) = (2<em>x </em>- 6), which simplifies to -<em>x </em>= -8, or
<em>x</em> = 8
Answer:
<h2>g(f(x)) = x² - 3</h2>
Step-by-step explanation:
f(x) = x²
g(x) = x - 3
In order to find g(f(x)), substitute f(x) into g(x), that's for every x in g(x) replace it with f(x)
We have
g(f(x)) = x² - 3

The answer is:
(x , y)
(0,-4)
Since 3 x 3 = 9, 9 is divisible by 3. So, 3 would be a factor of any number divisible by 9
