Answer:
Hey there!
The first equation has no solutions, as it is parallel lines.
The second equation has infinitely many solutions, as it is basically the same line, and the two lines intersect at infinite points.
The third equation is just one solution.
Let me know if this helps :)
Answer:
price of a sandwich = $7.50
Step-by-step explanation:
let the price of a sandwich be $x.
entire order cost= cost of chips+ 5×cost of sandwiches
= 1.25 + 5x
1.25 + 5x = 38.75
5x=38.75-1.25
5x=37.50
x=7.50
First you have to get it to y intercept for which is y=mx+b so you would subtract 7x and bring it to the other side so now u have -3y=7x+21 next u would divide -3 to get y alone so u would have now is y= -7/3x+ 7 then when u graph it the y intercept is 7 so u graph 7 on the y axis and the slope is -7/3 so u would go down 7 and over 3
