Answer:
Step-by-step explanation:
So first you multiply 6 by 55. That equals 330. Then, you divide that by 44. That equals 7.5. Therefore, Pablo runs 7.5 miles in 44 minutes.
Answer:
x=3, y=-6
Step-by-step explanation:
As you know there are many ways to solve this question! First is Subsitutuion, Second is Elimination, and Third is Graphing!
Let’s begin with our detailed answer:
As you know subsitution is solving for a variable and then it can be used as a variable substitution to figure out x and y.
So in our system of equations:
![\left \ {3x+2y=-3}} \atop {9x+4y=3}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%20%7B3x%2B2y%3D-3%7D%7D%20%5Catop%20%7B9x%2B4y%3D3%7D%7D%20%5Cright.)
I will just take one equation and solve for x but it actually dosent matter which variable you subsitutue and solve for.
![\left \ {3x+2y=-3}} \atop {9x+4y=3}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%20%7B3x%2B2y%3D-3%7D%7D%20%5Catop%20%7B9x%2B4y%3D3%7D%7D%20%5Cright.)
To eliminate this question we can divide the top part by -3:
![\left \ {-9x-6y=9}} \atop {9x+4y=3}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%20%7B-9x-6y%3D9%7D%7D%20%5Catop%20%7B9x%2B4y%3D3%7D%7D%20%5Cright.)
Let‘s sum these system of equation and we get: ![y=-6](https://tex.z-dn.net/?f=y%3D-6)
We can now insert y as -6 and solve for x:
![3x-12=-3](https://tex.z-dn.net/?f=3x-12%3D-3)
![x=3](https://tex.z-dn.net/?f=x%3D3)
So, ![x=3, y = -6](https://tex.z-dn.net/?f=x%3D3%2C%20y%20%3D%20-6)
Answer:
y-7=x-4
Step-by-step explanation:
If you change the equation to y=mx+b yout would get Y=x+3 plug in the point (4,7) and you would get 7=4+3
7=7 so that is correct.
