9 gallons of water
Divide the gallons by the number of plants.
6 ÷ 20 = 0.3
Multiply that by the number of plants you want.
0.3 x 30 = 9

Need the work for this. 192 is the answer

Art [367]

Replace x with 3:

y = -3 *4^3

y = -3 * 64

y = -192

What is mean of 8,3,3,7 and 4

Marina86 [1]

The mean is the average of the numbers. To obtain it, you add all the numbers together and divide by the number of numbers. So:

8+3+3+7+4= 25

25:5= 5

So the answer is: the mean is 5.

If y = kx, what is the value of k if y = 20 and x = 0.4? A) 5 B) 8 C) 9.6 D) 50

Margaret [11]

Answer: D, 50
y = kx y = 20 and x = 0.4

What you will do: You will plug in your y and your x.
Your equation should look like: 20=k(0.4)
Next: What you will do is divide each side of your equal sign by 0.4 so you will get your k alone.
You would get: k=50

Which statement is true about the domain of y = 3(2^-x)? Explain.

SVEN [57.7K]

We want to determine the domain of ${y=3 \cdot 2^{-x}=3 \cdot ({2^{-1}})^x=3 \cdot ({ \frac{1}{2}})^x$

any function of the form $y=f(x)=a \cdot b^x$ is called an "exponential function",
the only condition is that b is positive and different from 1, and a is a nonzero real number.

The domain of such functions is all real numbers.

That is for any x, the expression 3(2^-x) "makes sense".

Answer: The domain is all real numbers
