The form (f/g)(x) is equal to f(x) divided by g(x). From the equation given by the question, the form (f/g)(x) is just equal to (2x^2+x-3) divided by (x-1).
(f/g)(x) = (2x^2+x-3)/(x-1)
<span>(f/g)(x) = (2x+3)(x-1) / (x-1)
</span><span>(f/g)(x) = (2x+3)
</span>
To get the domain, equate (2x+3) to zero.
2x+3 = 0
x = -(3/2)
So the domain is all set of integers except -(3/2)
Answer:
The expression that models the growth of users is:
The rate of change per quarter is 7.5%
Step-by-step explanation:
Since the number of users is growing at a rate of 30% per year, then initially we have 5400, but after the first year we will have:
After the second year we will have:
After the third year we will have:
This will continue as the years passes. Therefore:
The rate of change pre quarter of year is the rate of change pre year divided by 4,therefore:
Answer:
B. 4.5
Step-by-step explanation:
(6x + 42)° and (18x - 12)° are alternate interior angles. If line l is parallel to line m, therefore,
6x + 42 = 18x - 12
Solve for the value of x. Combine like terms.
6x - 18x = -42 - 12
-12x = -54
Divide both sides by -12
-12x/-12 = -54/-12
x = 4.5
Therefore, x = 4.5 would prove lines l and m are parallel to each other.
The anwser is 3x-5 yuhhhhhhhhhhhhhhhhh
Answer:
