Answer:
Explanation:
in each of the following substitute x with the variables in the bracket.
f(a) = 5x - 6
= 5a - 6
f(a+h) = 5 (a + h) - 6
= 5a + 5h - 6
f(a+h) - f(a) = (5a + 5h - 6) - (5a - 6)
= 5a + 5h - 6 - 5a + 6
= 5h
(as the 5a's and 6's cancel each other out.)
f(a+h) - f(a)/h = 5a + 5h - 6 - ((5a - 6)÷h)
take l.c.m
= <u>(5ah + 5h^2 - 6h - 5a + 6)</u>
h
just substitute 10 into the equation
10=2x-6
add 6 to both sides
16=2x
divide both sides by 2
x=8
Answer: $383.25
Step-by-step explanation:
$6,570 X 70% = $4,599
$4,599/12= $383.25 per pay period
