Answer:
5) y=-3x+1 6) y=1/2x-1
Step-by-step explanation:
5) y-y1=m(x-x1)
y-(-5)=-3(x-2)
y+5=-3(x-2)
y=-3x+6-5
y=-3x+1
------------------
6) y-y1=m(x-x1)
y-1=1/2(x-4)
y=1/2x-4/2+1
y=1/2x-2+1
y=1/2x-1
Answer:
Perimeter = 4s
s = P/4
s = 48 in/4
s = 12 in
V = a^2h/3
h = 3V/a^2
h = 3(288 in^3)/ (12 in)^2
h = 864 in^3 / 144 in^2
h = 6 inches
Answer:
If is the amount of salt in the tank at time , then the rate at which the amount of salt in the tank changes is given by
Let's drop the units for now. We have
We're given that the water is pure at the start, so , giving
So the amount of salt in the tank (in lbs) at time is
Step-by-step explanation:
Answer: A
Step-by-step explanation: So, first of all, this is a linear graph, which is represented by the equation y = mx + b.
b = y-intercept. The y-intercept is the point in which the line crosses the y axis. Assuming this graph has units that go up by 1, the y- intercept for this line is 2, which eliminates choices B and C.
This graph is going down, which means it is negative, so the format should be -mx + b, which is answer choice A. Hope this helps! :)
