If f(x) = 3x - 1 and g(x) = x + 2, find (f + g)(x).

Alexxx [7]

Answer:

4x + 1

Step-by-step explanation:

Multiply f + g by x because f + g is in parenthesis:

f(x) + g(x)

Then implement equation #1 for f(x) into our equation:

3x - 1 + g(x)

Then implement the other equation for g(x) into our equation:

3x - 1 + x + 2

Then switch the positions of -1 and +x:

3x + x - 1 + 2

Simmplify:

4x + 1

Tara has a magnet collection from places she visited. She measures the length of the magnets to the nearest half inch and record

gregori [183]

Answer:

there are more magnets that longer than 2 1/2

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

From the photo, we can see that:

Length of the magnet:

1 inch there is 1 magnet
$1\frac{1}{2}$ inches there are 2 magnets
2 inches there are 3 magnets
3 inches there are 4 magnets
$3\frac{1}{2}$ there is 1 magnet
4 inches there are 2 magnets

=> the total number of magnets that longer than 2 1/2 are: 4+1+2 = 7

=> the total number of magnets that shorter than 2 1/2 are: 1+2+3 = 6

Hence, there are more magnets that longer than 2 1/2

Hope it will find you well.
