Can you also help me on this other equation
Write the equation of the line passing through (−1, 0) and (0, −3).
A) 3x - y = 3
B) x - 3y = 3
C) 3x + y = −3
D) x + 3y = −3
I suppose we are to determine the proportionality constant of the variation. The equation for this proportionality is,
y = kwx / z
Substituting the known values,
320 = k(6)(20)/3
The value of k from the equation is 8.
Answer:
T = 40 (minutes?)
Step-by-step explanation:
Given the equation G = 50 + 20T, where G = the total amount of gas and T = the amount of Time, we know that there is already 50 gallons of gas in the tank and that the rate at which it is pumped is 20 gallons per minute (I am assuming, though it is not stated in the problem). Given that the tank holds 850 gallons, we can plug in the values into the equation and solve for the missing variable, T:
850 = 50 + 2T
Subtract 50 from both sides: 850 - 50 = 50 + 2T - 50 or 800 = 2T
Divide 2 from both sides: 800/2 = 2T/2
Solve for T: 40 = T
There are 2×2×2×2×2×2 = 2⁶ = 64 possible settings.
_____
Each switch can be in 2 positions, and for each of those, the other switches can have all possible settings. 1 switch has 2 settings. 2 switches will have 2×2 settings. 3 switches will have 2×2×2 settings.
