Answer:
Option B
Step-by-step explanation:
Vertical x= -5, x= -3, Horizontal y=3x-4 (slant)
First we are going to set up two equations:
1) ![x+y=168](https://tex.z-dn.net/?f=%20x%2By%3D168%20)
2) ![y=3x](https://tex.z-dn.net/?f=%20y%3D3x%20)
where x is the number of hotdogs sold, and y is the number of sodas sold. Let's subtract x from the second equation and set equal to 0:
1) ![x+y=168](https://tex.z-dn.net/?f=%20x%2By%3D168%20)
2) ![3x-y=0](https://tex.z-dn.net/?f=%203x-y%3D0%20)
Then let's add the two equations together to cancel out the y variable:
![x+y=168](https://tex.z-dn.net/?f=%20x%2By%3D168%20)
+ ![3x-y=0](https://tex.z-dn.net/?f=%203x-y%3D0%20)
---------------------------------
![4x=168](https://tex.z-dn.net/?f=%204x%3D168%20)
Then solve for x:
![x=42](https://tex.z-dn.net/?f=%20x%3D42%20)
So then return to equation 1 and plug in x to solve for y:
![x+y=168](https://tex.z-dn.net/?f=%20x%2By%3D168%20)
![42+y=168](https://tex.z-dn.net/?f=%2042%2By%3D168%20)
![y=126](https://tex.z-dn.net/?f=%20y%3D126%20)
So then we know that x = 42 and y = 126; therefore, there were 42 hotdogs sold, and there were 126 sodas sold.
B<em> (That’s the answeeerrr)</em>
Answer:
the slope is 3 and 1 and the y intercept is 1 and 1
Step-by-step explanation:
Answer:
see the explanation
Step-by-step explanation:
we know that
To determine the rate per pretzel or unit rate, divide the total paid by the number of pretzel
so
![\frac{126}{42}=\$3\ per\ pretzel](https://tex.z-dn.net/?f=%5Cfrac%7B126%7D%7B42%7D%3D%5C%243%5C%20per%5C%20pretzel)
<em>Jaimie's error</em>
He subtracted 42 from $126 when he should have divided $126 by 42
