Answer:
yes because |x+y|=|x|+|y| is just the same equation just splitting the numbers
They both are the same absolute value equation
Step-by-step explanation:
|x+y|=|x|+|y|
x+y=|x|+|y|
x+y=x+y

Let x be the number of people that can be seated.
The value of x is some number 0 or greater, such that this number is a whole number (we can't have half a person). This means that
![x \ge 0](https://tex.z-dn.net/?f=x%20%5Cge%200)
which is the same as saying
![0 \le x](https://tex.z-dn.net/?f=0%20%5Cle%20x)
The instructions state that we can seat up to 1200 people. This is the max capacity. We can't go over this amount. So we will also have
![x \le 1200](https://tex.z-dn.net/?f=x%20%5Cle%201200)
indicating that x can be less than 1200 or equal to 1200.
So putting the two inequalities together, we get
![0 \le x \le 1200](https://tex.z-dn.net/?f=0%20%5Cle%20x%20%5Cle%201200)
Note: if you haven't learned about compound inequalities yet, then the teacher may only want
![x \le 1200](https://tex.z-dn.net/?f=x%20%5Cle%201200)
as the answer.
Answer:
One time
Step-by-step explanation:
In both the numbers 72 and 78, the place value of 7 is 70.
Hence, 7 in 72 represents one time the value of the 7 in 78.
Answer:
![f(x)-g(x)=\frac{-1}{4}x^{4}-3x^{3}](https://tex.z-dn.net/?f=f%28x%29-g%28x%29%3D%5Cfrac%7B-1%7D%7B4%7Dx%5E%7B4%7D-3x%5E%7B3%7D)
Step-by-step explanation:
This is a subtraction between polynomials, since both functions are polynomials, hence, to solve the problem with need to perform the subtraction, by coefficients.
![f(x)= \frac{1}{2}x^{4}+0x^{3}-x^{2}\\\\g(x)=\frac{3}{4}x^{4}+3x^{3}-x^{2}](https://tex.z-dn.net/?f=f%28x%29%3D%20%5Cfrac%7B1%7D%7B2%7Dx%5E%7B4%7D%2B0x%5E%7B3%7D-x%5E%7B2%7D%5C%5C%5C%5Cg%28x%29%3D%5Cfrac%7B3%7D%7B4%7Dx%5E%7B4%7D%2B3x%5E%7B3%7D-x%5E%7B2%7D)
By performing the subtraction, we have:
![f(x)-g(x)=\frac{-1}{4}x^{4}-3x^{3}](https://tex.z-dn.net/?f=f%28x%29-g%28x%29%3D%5Cfrac%7B-1%7D%7B4%7Dx%5E%7B4%7D-3x%5E%7B3%7D)
