Answer:

1st option

Step-by-step explanation:

To find (f ￮ g)(x) substitute g(x) into f(x) , that is

f( $\frac{1}{2x}$ )

= $\frac{2}{\frac{1}{2x}+3 }$

= $\frac{2}{\frac{1+6x}{2x} }$

= $\frac{4x}{1+6x}$

Solve, using the correct order of operations, when x = 7 and y = 3 (x – 3) + 2y

sweet [91]

Answer:

Step-by-step explanation:

Since it given that:

x = 7 and y = 3

We can substitute x and y:

(7-3) + 2(3)

7 - 3 = 4

4 + 2(3)

2(3) = 6

4 + 6 =10

Thus the answer is 10.

G(n)=-n^3+3n^2, find g(-4)

Sauron [17]

Answer:

g(-4) = 112

Step-by-step explanation:

Hi there!

$g(n)=-n^3+3n^2$

To find g(-4), replace all n's with -4:

$g(-4)=-(-4)^3+3(-4)^2\\g(-4)=-(-64)+3(16)\\g(-4)=64+48\\g(-4)=112$

I hope this helps!

STatiana [176]

Answer:

16.65 feet

Step-by-step explanation:

Okay, we have three boards that are each 6.85 feet long. If we cut 3.4 feet off one board, that board has:

6.85

−

3.4

3.45

feet left

If we cut off 0.5 feet off another board, that board has:

6.85

−

0.5

6.35

feet left

So, if we take our three new boards, the total length of plywood left is:

6.85

3.45

6.35

16.65

feet

Hope this helps!
