Answer: 0
Explanation:
-1/2n -(-1/2n)
= -1/2n + 1/2n
= 0
If it cost $200 per month and you are makeing $900 per month you are making money off the machine.
Answer:
f(n) = 74 + 11(n - 1)
<u>For the 7th term</u>
n = 7
f(7) = 74 + 11(7 - 1)
= 74 + 11(6)
= 74 + 66
<h2>= 140</h2>
<u>For</u><u> </u><u>the</u><u> </u><u>8</u><u>t</u><u>h</u><u> </u><u>ter</u><u>m</u>
n = 8
f(8) = 74 + 11( 8 - 1)
= 74 + 11(7)
= 74 + 77
<h2 /><h2>= 151</h2>
Hope this helps you
Answer:
(f + g)(x) = x² + 4x - 4
Step-by-step explanation:
The statement (f + g)(x) is the same as f(x) + g(x). In other words, the question simply wants you to add the two functions together.
f(x) = 4x + 1
g(x) = x² - 5
(f + g)(x) <----- Original statement
f(x) + g(x) <----- Rewrite
(4x + 1) + (x² - 5) <----- Substitute the equations in f(x) and g(x)
4x + x² - 4 <----- Add 1 and -5
x² + 4x - 4 <----- Rearrange the terms
