Answer:
A
Step-by-step explanation:
Use the quadratic formula
Answer:
y= 13/2x +12
Step-by-step explanation:
so first move expression to right hand side
13x-2y+24=0
2y= 13x+24
then divide every term by 2 to cancel out 2
2y/2 = 13x/2 + 24/2
and then you get your final answer
B) Exponential. Because it keeps losing 20% of what the previous years amount was so it decreases by a smaller factor each year
X= 23+8y
X represents the total
23 represents the base price
8 represents the price per extra hour
Y represents how many hours extra
