I believe you get 10 dollars in interest.
A I think I don’t know cause the formula is y=Mx+b is a slope formula so he have to be right
Multply both equations by 2 leaving
x + 2y = 8
x - 2y = -2
Add the equations giving
2x = 6
x = 3
Substitute 3 in the top equation
3 + 2y = 8
2y = -5
y = -2.5
Answer:
x= -2
Step-by-step explanation:
-3x-5=1
+5 on each side to balance the equation:
-3x=6
Divide by -3 on each side:
x=-2
The answer is A.) A smaller percentage of second-lunch students (18%) eat outside.
