Intersecting point 4,2 with slope of 1/2
3(5)-15+10(7)-2(5)
15-15+70-10
=60
The answer is 60
Solve for y...
2xy=1
y=1/(2x)
So this is a function as each x value (with the exception of x=0) produces just one value for y. However, technically there is a vertical asymptote about the vertical line x=0. So there is a discontinuity as x=0.
I say this technically, because most would say that this function is true even with the discontinuity (as they do with say y=tana), but technically the discontinuity makes this not a function because another requirement of a function is for their to be an actual output value for each input value. In this case division by zero when x=0 is undefined and cannot be included as part of a function. So if you are picky about being absolute, 2xy=1 is really two functions. One with a domain of (-oo,0) and another with a domain of (0,+oo).
Answer:
500 plants
Step-by-step explanation:
Total capacity of barrel = 150 L
1 liter = 1000 mL
Total capacity of barrel in mL = 150*1000 mL = 150,000 mL
amount of water given to each plant by Mattie = 300 mL
Let there be x plants
Then, total amount of water given to x plant by Mattie = 300*x mL
We know that full rain barrel has 150,000 mL
so total amount of water given to x plant by Mattie should be equal to full rain barrel capacity.
Substituting value of full rain barrel capacity and total amount of water given to x plant
Mathematically it can be written as
total amount of water given to x plant by Mattie = full rain barrel capacity
300*x mL = 150,000 mL
=> x = 150,000/300 = 500
Thus, 500 plants can she water with a full rain barrel.
