each bottle holds 16 fluid ounces of water. bottles or package in four rows of six bottles. how many ounces of water are in each
Evgen [1.6K]
Data:

1 bottle → 16 fluid ounces

package (4x6) bottles = 24 bottles

Solving: (<span>By the rule of three)
</span>
1 bottle → 16 fluid ounces
24 bottles → y

\frac{1}{24} = \frac{16}{y}
multiply cross
1*y = 24*16
\boxed{y = 384\:fluid\:ounces}\end{array}}\qquad\quad\checkmark

Answer:
384 ounces of water

Use the intersect method to solve the equation.<br><br> x^2-7= -x^2+1
sineoko [7]
<span>The intersect method would use the graphs of both equations to find points where they would cross each other. In this instance, the graphs would cross each other at two points: x = +/-2. (To solve this in the "traditional" form, add x^2 to both sides and then add 7 to both sides, leaving 2x^2 = 8, dividing 2 out to leave x^2 = 4. The square root of 4 = +/-2, as noted.)</span>

I want someone explain me please
JulsSmile [24]
The unit rate meant the slope, which is represented by m in y=mx+b
First we must isolate the y by dividing both sides by -1 to get:
y=-x/7 or y=(-1/7)x, so the the unit rate is -1/7 or B

Hope this helps :)

Given the function f(x) = 2^x, find the value of f^−1(32).
klio [65]
f(x)= 2^{x}

We are to find the value of f^{-1}(32)

First we need to find the inverse of f(x) . The inverse of 2^{x} is \frac{ln(x)}{ln(2)}.

Steps to find inverse of f(x) are shown below in the image.

So f^{-1}(32) = \frac{ln(32)}{ln(2)}=5

Therefore, the correct answer is option C
