Answer:
You have to know the basic properties of exponents.
Jill's answer is wrong because you add the powers when there are like bases. You don't multiply.
-3+6=3
The base stays the same.
This equation is linear, which means that it goes up by the same amount every time you increase X by one.
The general form of a linear equation is <span>y=m∗x+b</span>
where m is the slope and b is the y-intercept. The y-intercept indicates where the equation starts at x=0. In this case, it's 250, meaning that buying the commercial slot cost $250.
m, on the other hand, is the slope of the graph. Here we have 100, meaning that it costs $100 per second to run the commercial. This can be visualized like so:<span>y(0)=100∗0+250=250</span><span>y(1)=100∗1+250=350</span><span>As you can see, the cost went up by $100 after one second.
In general, the slope represents the amount added per time, whilst the y-intercept represents the initial amount.</span>
The domain of the composite function is given as follows:
[–3, 6) ∪ (6, ∞)
<h3>What is the composite function of f(x) and g(x)?</h3>
The composite function of f(x) and g(x) is given as follows:
In this problem, the functions are:
- .
The composite function is of the given functions f(x) and g(x) is:
The square root has to be non-negative, hence the restriction relative to the square root is found as follows:
The denominator cannot be zero, hence the restriction relative to the denominator is found as follows:
Hence, from the restrictions above, of functions f(x), g(x) and the composite function, the domain is:
[–3, 6) ∪ (6, ∞)

Answer:
-2/5
Step-by-step explanation:
2/5 + -4/5 becomes 2/5-4/5
2/5-4/5= -2/5
