The answer for the first on 8 and the second one is 9
Answer:
Step-by-step explanation:
9L/4days = 2L/1day, which is the unit rate.
Over the course of 4 days: (2L/day)(4 days) = 8 Liters
Slope of 2y = x + 5:-
This is y = 0.5 x + 2.5 in slope intercept form so its slope = 0.5
Slope of the line perpendicular to it = -1 / 0.5 = -2
it passes through (2 , 1) so we have
y- 1 = -2(x - 2)
y = -2x + 4 + 1
The answer is y = -2x + 5
