Answer:

x = x; the solution has infinite solutions

Step-by-step explanation:

3(x+ 7) = 3x + 21; distribute the 3 on the left side

3x + 21 = 3x + 21; now subtract 21 from both sides

3x = 3x; divide by 3

x = x; the solution has infinite solutions. Since both terms are equal any value for x will be true on this equation.

4.) solve for f(g(2))

Westkost [7]

Answer:

$f(g(2))=10$

Step-by-step explanation:

We have the two functions: $f(x)=3x-5$ and $g(x)=2+\frac{6}{x}$ .

We want to find $f(g(2))$ .

So, let's use the second function to find $g(2)$ first:

$g(2)=2+\frac{6}{2}$

Divide:

$g(2)=2+3$

Add:

$g(2)=5$

Therefore, our expression is the same to $f(g(2))=f(5)$ .

Now, we can substitute 5 for f(x). This yields:

$f(5)=3(5)-5$

Multiply:

$f(5)=15-5$

Subtract:

$f(5)=10$

So:

$f(g(2))=10$

And we're done!

2x^2-12x+16 factor completely

harkovskaia [24]

Answer:

2 (x-4) (x-2)

Step-by-step explanation:

2x^2-12x+16

Factor out a 2

2( x^2 -6x +8)

Now we factor the inside term

What multiplies to 8 and add to -6

-4*-2 =8

-4+-2 = -6

2 (x-4) (x-2)
