Answer:

The final expression should be 4x-1

Step-by-step explanation:

The error occurs in the simplification from the 3rd to 4th step. You can see two positive 2x's, but suddenly they vanish.

4 + 2x - 5 + 2x

4 - 5 + 4x

-1 + 4x

4x -1

Let f(x)=4x+9. Write a function g whose graph is a reflection in the y-axis of the graph of f. g(x)= ?

frez [133]

Answer:

$g(x)=-4x+9$

Step-by-step explanation:

So we know that:

$f(x)=4x+9$

To reflect across the <em>y-axis</em>, instead of x, use -x. Therefore:

$g(x)=f(-x)=4(-x)+9$

Simplify:

$g(x)=-4x+9$

And that's our answer :)

Can I get help someone

Answer:

m ≤ 4250

Step-by-step explanation:

What we know:

Mr. Loureiro has to pay $25 plus 10 cents every mile.

The equation becomes 25 + 0.1x = 450

25 + 0.1x = 450

0.1x = 450 - 25

0.1x = 425

x = 4250

So, Mr. Loureiro can travel no more than 4250 mi. (m ≤ 4250)
