Answer:
(f +g)(2) = -7
Step-by-step explanation:
Functions are added by adding their values.
<h3>Application</h3>
(f +g)(2) = f(2) +g(2)
= (2 -8) +(4(2) -9) . . . . . evaluate f and g with z=2
= -6 +(-1)
(f +g)(2) = -7
Hope this will help you if I am answering this right.
To solve this problem, all we have to do is to closely
analyze the situation. Now we are given that the amount of saving per week is
equivalent to one fifth (1 / 5) of Ben’s weekly pay (or weekly salary).
Now we are to find the weekly pay or weekly salary that
result in weekly savings of $61.50. So we can see that actually the value of
61.50 is one fifth (1 / 5) of W, therefore:
(1/ 5) W = 61.50
W = 5 * 61.50
W = $307.5
<span>Therefore a weekly pay of $307.5 will result in a weekly
savings of $61.50</span>
Answer:
x - 1 and 5x - 7
Step-by-step explanation:
f(x) + g(x)
= 3x - 4 - 2x + 3 ← collect like terms
= x - 1
f(x) - g(x)
= 3x - 4 - (- 2x + 3) ← distribute parenthesis by - 1
= 3x - 4 + 2x - 3 ← collect like terms
= 5x - 7
