A. The slope is 3.75 because that’s how much the total cost is increasing by when a drink is being added
B. The y-intercept is 6.25 because that is the total cost when the number of drinks(x) is zero.
C. y=3.75x+6.25
Answer:
n > 10
n < 9
Interval notation:
(-∞, 9) U (10, ∞)
Step-by-step explanation:
2n + 7 > 27 or 3 + 3n < 30
-7 -7 -3 -3
2n > 20 3n < 27
÷2 ÷2 ÷3 ÷3
n > 10 n < 9

I hope this helps!
I don’t know really but my guess is 62%
Answer:
y intercept = (0,-1.2)
x intercept = (3.6,0)
Step-by-step explanation:
For y-int, x=0
3(0)-9(y)=10.8
9y=-10.8
y= -1.2
For x-int, y =0
3x - 9(0)=10.8
3x=10.8
x=3.6
