C) Billion gallons per day, because the independent quantity is time in days and dependent quantity is volume of water in billion gallons.
Hope this helps!!
Answer:
- 13
Step-by-step explanation:
To evaluate (g ○ f)(3), evaluate f(3) then use this value to evaluate g(x)
f(3) = 3 - 7 = - 4, then
g(- 4) = 4(- 4) + 3 = - 16 + 3 = - 13
Answer:
221 minutes
Step-by-step explanation:
His goal is 8 minutes or less for every mile during the marathon.
8 x 52 = 416
That gives him 416 total minutes to complete the marathon goal.
He already ran the first half in 195 minutes, so we do this to find the time for the other half:
416 - 195 = 221
He has 221 minutes in the second half of the marathon to meet his goal.
Answer: One solution
Step-by-step explanation:
y = 3x + 3
y = -2x + 3
-----------------------------------------------------------------------------------------------------------
To solve this, you need to understand a few things:
a) If two lines have the same slope but different y-intercepts, they are parallel when graphed and thus do not have any solutions
b) If two lines have the same slope and same y-intercepts, they are the same line when graphed and thus do not have infinitely many solutions
c) If two lines have different slopes (and/or y-intercepts), they have one solution
-----------------------------------------------------------------------------------------------------------
These two lines have different slopes but the same y-intercept (condition c)
So they have one solution
