7 2/3 - 5 5/8 = 7 16/24 - 5 15/24 = 2 1/24
10 is the initial value, found when x=0. I don't know what you are measuring by "0" and "10" here, so can't be more specific.
It is a function because each x value only has one y value
10/24 x 100 = 41.66
Approximately 42% of her day
Answer:
B) -4
Step-by-step explanation:
(5/2)x + y = 2
x + (2/3)y = 4
y = 2 - (5/2)x
x + (2/3)(2 - (5/2)x) = 4
x + 4/3 - (5/3)x = 4
(-2/3)x = 8/3
-2x = 8
x = -4
