Answer:
So, negatives cancel each other out.
Step-by-step explanation:
The answer is 63.
A negative times a negative gives you a positive.
-9 x -7 brings you = 63.
Answer:
792m^2
Step-by-step explanation:
Seperate your 2 rectangles
Large one is 18*30
Small one (60-18)*6
18*30 = 540m^2
42*6=252m^2
The table models an exponential relationship, and the equation of the table is ![y = 4(1/2)^x](https://tex.z-dn.net/?f=y%20%3D%204%281%2F2%29%5Ex)
<h3>How to analyze the table of values?</h3>
The table of values is given as:
x 0 1 2 3 4
y 4 2 1 1/2 1/4
The above table shows an exponential model
An exponential model is represented as:
![y = ab^x](https://tex.z-dn.net/?f=y%20%3D%20ab%5Ex)
When x = 0 and y = 4, we have
![ab^0 = 4](https://tex.z-dn.net/?f=ab%5E0%20%3D%204)
Evaluate
a = 4
When x = 1 and y = 2, we have
![ab^1 = 2](https://tex.z-dn.net/?f=ab%5E1%20%20%3D%202)
Evaluate
![ab = 2](https://tex.z-dn.net/?f=ab%20%20%3D%202)
Substitute 4 for a
4b = 2
Divide both sides by 4
b = 1/2
Substitute 4 for a and 1/2 for b in ![y = ab^x](https://tex.z-dn.net/?f=y%20%3D%20ab%5Ex)
![y = 4(1/2)^x](https://tex.z-dn.net/?f=y%20%3D%204%281%2F2%29%5Ex)
Hence, the equation of the table is ![y = 4(1/2)^x](https://tex.z-dn.net/?f=y%20%3D%204%281%2F2%29%5Ex)

Given a function in a table or in algebraic or graphical form, identify key features such as x- and y-intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; and end behavior. Use key features of an algebraic function to graph the function.
