Answer:
![\left\{\begin{matrix}x+y=10\\ 0.05x+0.10y=0.85\end{matrix}\right.](https://tex.z-dn.net/?f=%5Cleft%5C%7B%5Cbegin%7Bmatrix%7Dx%2By%3D10%5C%5C%200.05x%2B0.10y%3D0.85%5Cend%7Bmatrix%7D%5Cright.)
Step-by-step explanation:
<u>System of Equations</u>
Let's call:
x = number of nickels in the student's pocket
y = number of dimes in the student's pocket
Each nickel has a value of $0.05, so x nickels have a value of 0.05x
Each dime has a value of $0.10, so y dimes have a value of 0.10y
The student has a total of 10 coins, thus:
![x+y=10](https://tex.z-dn.net/?f=x%2By%3D10)
The total value of the coins is $0.85, thus
![0.05x+0.10y=0.85](https://tex.z-dn.net/?f=0.05x%2B0.10y%3D0.85)
The system of linear equations that represents this scenario is:
![\left\{\begin{matrix}x+y=10\\ 0.05x+0.10y=0.85\end{matrix}\right.](https://tex.z-dn.net/?f=%5Cleft%5C%7B%5Cbegin%7Bmatrix%7Dx%2By%3D10%5C%5C%200.05x%2B0.10y%3D0.85%5Cend%7Bmatrix%7D%5Cright.)
Im pretty sure the correct answer is the fourth one
The answer is to this question is a)strong positive...
Answer:
2
Step-by-step explanation:
this is because the inequality sign says greater than OR equal too, this would make the line solid, and since it's greater, all the values above that line would be included in the inequality
