Answer:
b. y = -9
Step-by-step explanation:
A line with zero slope has no dependence on x. It is simply ...
... y = constant
The constant must be the same as the y-value of the point you want the line to go through. Since the point is (12, -9), the constant is -9 and the equation is ...
... y = -9
It is quite simple actually since it is simple division with the negative rules.
Just simplify the problem and use the negatives to determine if it is positive or negative. (two negatives equal a positive and one negative equals a negative)
The inequality for the maximum number of bottles of juice she can buy
6.13+ 2.08b <20.00
Option B
Given
Melissa has $20 to buy bagels and juice for her class
Box of bagels : 6.13 including tax
Bottle of juice: 2.08 including tax
She will buy only one box of bagels that is for 6.13
Let 'b' be the number of bottles of juice she can buy
Total cost should be less than 20 dollars
6.13(one bagels) +2.08(bottles of juices)<20
So the inequality becomes
