<em>g(x)</em> = <em>x</em>² - <em>x</em> - 6
so
<em>g</em> (-4) = (-4)² - (-4) - 6 = 16 + 4 - 6 = 14
When <em>g(x)</em> = 6, we have
6 = <em>x</em>² - <em>x</em> - 6
<em>x</em>² - <em>x</em> - 12 = 0
Solve for <em>x</em>. We factorize this easily as
(<em>x</em> - 4) (<em>x</em> + 3) = 0
which gives
<em>x</em> - 4 = 0 <u>or</u> <em>x</em> + 3 = 0
<em>x</em> = 4 <u>or</u> <em>x</em> = -3
Answer: 25 tables.
Step-by-step explanation:
5 • 10*2= 500 (10*2= 100, then 100 times 5)
2 • 10*1= 20 (10*1= 10, then times 2)
Therefore a cafeteria can seat 500 students. Each table had 20 seats.
Divide 500/20 and get 25.
Hope this helps

Answer:
5
Step-by-step explanation:
1/3(12+3x6)-5
Multiply 3 and 6 to get 18.
1/3(12+18)-5
Add 12 and 18 to get 30.
1/3x30-5
Multiply 1/3 and 30 to get 30/3
30/3-5
Divide 30 by 3 to get 10.
10−5
Subtract 5 from 10 to get 5.
5
