Answer:
x=8
Step-by-step explanation:
4(x+11)=76
4x + 4(11) = 76
4x + 44 = 76
4x = 76-44
4x = 32
x = 32/4
x = 8
The original function is
f(x)=√x
As this is condition for √x function, x≥ 0
So,
Domain= [0, infinity)
Range= [0, infinity)
After the reflection across x-axis and y-axis, we get a function,
g(x)=-√-x
-x≥ 0 means x≤ 0,
So,
Domain= (-infinity, 0]
Range= (-infinity, 0]
From this you can see that
-The only value that is in the domains of both functions is 0.
-The range of g(x) is all values less than or equal to 0.
only these points are correct and all other points are wrong.
See the attached graphs for both functions.
Answer:
7
Step-by-step explanation:
2n + 4n = 6n, adding like terms
6n = 42
6n/6 = 42/6
n = 7

Answer:</h2>
<em>x = 6, x = 44; The zeros represent the number of monthly memberships where no profit is made.</em>
<h2>
Explanation:</h2>
Here we have the function:
that models the profit in dollars, where x is the number of memberships sold. In order to get the zeros we'll use the quadratic formula:
So the zeros are:
The zeros occurs when , so we can conclude that at those points there is no any profit.
In conclusion:
<em>x = 6, x = 44; The zeros represent the number of monthly memberships where no profit is made.</em>
Answer: $52556.40
Step-by-step explanation:
Price per share = $112.30
Number of shares = 450
Cost of the shares = 450 × $112.30 = $50535
Since there is a 4% commission, the total cost of the purchase will be:
= $50535 + (4% × $50535)
= $50535 + (0.04 × $50535)
= $50535 + $2021.40
= $52556.40
