Answer:
Step-by-step explanation:
let the price of one shirt be x and one pant be y
Eli--> x+y=600------eq1
Simin-->4x+2y=1500-----eq2
Solve both the equations
multiply eq1 x 4= 4x+4y=2400
now subtract ew2 from 1
you will get y=450 and x=150
so price of one shirt=150 kr
Hello there!
The median is the middle of the data set. Since we only have 7 numbers, we can arrange it from greatest to least, however the program has already done that. So, to find the median for this data set, all we have to do is simply find the middle number. The median would be 9 for this data set.
Lets simplify each one of the rational expressions using the product rule of exponents:
![a^n*a^m=a^{n+m}](https://tex.z-dn.net/?f=a%5En%2Aa%5Em%3Da%5E%7Bn%2Bm%7D)
and the quotient rule of exponents:
![\frac{a^n}{a^m} =a^{n-m}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%5En%7D%7Ba%5Em%7D%20%3Da%5E%7Bn-m%7D)

![\frac{-3x^2}{2y^2} * \frac{y^2}{9x} =- \frac{x}{6} = \frac{-1}{6} x](https://tex.z-dn.net/?f=%20%5Cfrac%7B-3x%5E2%7D%7B2y%5E2%7D%20%2A%20%5Cfrac%7By%5E2%7D%7B9x%7D%20%3D-%20%5Cfrac%7Bx%7D%7B6%7D%20%3D%20%5Cfrac%7B-1%7D%7B6%7D%20x)

![\frac{5y^2}{10x^2} * \frac{4x^2}{y} =2y](https://tex.z-dn.net/?f=%20%5Cfrac%7B5y%5E2%7D%7B10x%5E2%7D%20%2A%20%5Cfrac%7B4x%5E2%7D%7By%7D%20%3D2y)

![\frac{-9y^2}{5x} * \frac{-10x^2}{3y} =6xy](https://tex.z-dn.net/?f=%20%5Cfrac%7B-9y%5E2%7D%7B5x%7D%20%2A%20%5Cfrac%7B-10x%5E2%7D%7B3y%7D%20%3D6xy)

We can conclude that you should pair the rational expressions with their simplest form as follows:
![6xy-----\ \textgreater \ \frac{-9y^2}{5x} * \frac{-10x^2}{3y}](https://tex.z-dn.net/?f=6xy-----%5C%20%5Ctextgreater%20%5C%20%5Cfrac%7B-9y%5E2%7D%7B5x%7D%20%2A%20%5Cfrac%7B-10x%5E2%7D%7B3y%7D)
![\frac{-1}{6} x-----\ \textgreater \ \frac{-3x^2}{2y^2} * \frac{y^2}{9x}](https://tex.z-dn.net/?f=%5Cfrac%7B-1%7D%7B6%7D%20x-----%5C%20%5Ctextgreater%20%5C%20%20%5Cfrac%7B-3x%5E2%7D%7B2y%5E2%7D%20%2A%20%5Cfrac%7By%5E2%7D%7B9x%7D%20)
![-4x-----\ \textgreater \ \frac{14x^2}{5y} * \frac{-10y}{7x}](https://tex.z-dn.net/?f=-4x-----%5C%20%5Ctextgreater%20%5C%20%5Cfrac%7B14x%5E2%7D%7B5y%7D%20%2A%20%5Cfrac%7B-10y%7D%7B7x%7D)
Answer:
A) A number line with a closed circle on 3 and shading to the right.
Step-by-step explanation:
For the solutions of the function the highest possible x value can be 3 anything higher than that make the inequality false.
6x-12
Combine 2x and 4x = 6x
Combine -17 and 5 = -12
