Answer:
The system has one solution.
Step-by-step explanation:
To find the number of solutions of the system, we equal both equations for y.
If we have ax = b, in which both a and b are different of 0, we have one solution.
If both a and b are 0, we have infinite solutions.
If a is 0 and b is not, there are no solutions.
y=6/7x-8 and y=7/9x+10/9
So
![\frac{6x}{7} - 8 = \frac{7x}{9} + \frac{10}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B6x%7D%7B7%7D%20-%208%20%3D%20%5Cfrac%7B7x%7D%7B9%7D%20%2B%20%5Cfrac%7B10%7D%7B9%7D)
![\frac{6x}{7} - \frac{7x}{9} = \frac{10}{9} + 8](https://tex.z-dn.net/?f=%5Cfrac%7B6x%7D%7B7%7D%20-%20%5Cfrac%7B7x%7D%7B9%7D%20%3D%20%5Cfrac%7B10%7D%7B9%7D%20%2B%208)
![\frac{54x - 49x}{63} = \frac{10}{9} + \frac{72}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B54x%20-%2049x%7D%7B63%7D%20%3D%20%5Cfrac%7B10%7D%7B9%7D%20%2B%20%5Cfrac%7B72%7D%7B9%7D)
![\frac{5x}{63} = \frac{82}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B5x%7D%7B63%7D%20%3D%20%5Cfrac%7B82%7D%7B9%7D)
![45x = 63*82](https://tex.z-dn.net/?f=45x%20%3D%2063%2A82)
Both a and b are different of 0, so the system has one solution.
Answer:
$8.26
Step-by-step explanation:
We have 15.71 total. Chicken nuggets each cost $1.49. We are ordering 5 orders of chicken nuggets, so we use multiplication. 1.49*5= $7.45. Since we spent 7.45 from 15.71, to find the rest, we subtract. 15.71-7.45 = 8.26
The slope of line D is also -4 because the lines are perpendicular.
