Answer:

5x +3

Step-by-step explanation:

f(x) = 2x-6

g(x) = 3x+9

(f+g) (x) = 2x-6+ 3x+9

Combine like terms

= 5x +3

We are given the following two equations:

$f(x)=2x-6$

$g(x)=3x+9$

To find (f+g)(x), we just add f(x) and g(x) and simplify:

$(f+g)(x)=f(x)+g(x)$

$=2x-6+3x+9$

$=5x+3$

Let me know if you need any clarifications, thanks!

Makayla works as a teacher at Dacula Middle School. She earns $150 just for coming to work and an additional $200 for each hour

IRINA_888 [86]

$\\ \bull\longmapsto T(7)$

$\\ \bull\longmapsto 200x+150$

$\\ \bull\longmapsto 200(7)+150$

$\\ \bull\longmapsto 1400+150$

$\\ \bull\longmapsto 1550$

You invest $15,000 to start a hot dog stand at the local sports complex. It costs you $.65 to produce each hot dog. How many hot

SCORPION-xisa [38]

Answer:

Below is the procedure to find the answer: 30,000 hot dogs.

Explanation:

The <em>average cost </em>is found dividing the total cost by the number of hot dogs:

$Average\text{ }cost=Total\text{ }cost/Number\text{ }of\text{ }hot\text{ }dogs$

The total cost is the the sum of amount that you invest plus the product of the cost of producing each hot dog times the number of hot dogs:

$Total\text{ }cost=investment+Number\text{ }of\text{ }hot\text{ }dogs\times cost\text{ }to\text{ }produce\text{ }each\text{ }hot\text{ }dog$

Substitute the values:

$Total\text{ }cost=15,000+0.65x\\ \\ Averate\text{ }cost=(15,000+0.65x)/x=1.15$

Where x is the number of hot dogs.

Solve for x from the equation:

$(15,000+0.65x)/x=1.15\\ \\ 15,000+0.65x=1.15x\\ \\ 15,000=1.15x-0.65x\\ \\ 15,000=0.5x\\ \\ 15,000/0.5=x\\ \\ 30,000=x\\ \\ x=30,000$

Which shows you how you can find that the answer is 30,000 hot dogs.
