Step-by-step explanation:

5^(3b−1) = 5^(b−3)

Since the bases are equal, the exponents must also be equal.

3b − 1 = b − 3

2b = -2

b = -1

On average, Stan drinks 3/4 of a 8 ounce glass of water in 1/2 of an hour.
sweet [91]
<h3>Stan drinks 12 ounces of water in 1 hour</h3>

<em><u>Solution:</u></em>

Given that,

Stan drinks 3/4 of a 8 ounce glass of water in 1/2 of an hour

Which means,

\frac{3}{4}\ of\ 8\ ounce = \frac{1}{2}\ hour

\frac{3}{4} \times 8 = 0.5\ hour\\

Therefore,

6 ounces is drank in 0.5 hour

We have to find the water he drinks in an hour

Let "x" be the water he drinks in 1 hour

Thus we get,

6 ounce = 0.5 hour

x ounces = 1 hour

This forms a proportion and we can solve the sum by cross multiplying

6 \times 1 = 0.5 \times x\\\\0.5x = 6\\\\x = \frac{6}{0.5}\\\\x = 12

Thus, he drinks 12 ounces of water in 1 hour

What is the equation when y=5x+4 is reflected over the x-axis, y-axis &amp; y=x?
tigry1 [53]

Answer:

A) y=-5x-4

B) y=-5x+4

C) y=\frac{x-4}{5}

Step-by-step explanation:

So we have the equation:

y=5x+4

Let's write this in function notation. Thus:

y=f(x)=5x+4

A)

To flip a function over the x-axis, multiply the function by -1. Thus:

f(x)=5x+4\\-(f(x))=-(5x+4)

Simplify:

-f(x)=-5x-4

B) To flip a function over the y-axis, change the variable x to -x. Thus:

f(x)=5x+4\\f(-x)=5(-x)+4

Simplify:

f(-x)=-5x+4

C) A reflection over the line y=x is synonymous with finding the inverse of the function.

To find the inverse, switch x and f(x) and solve for f(x):

f(x)=5x+4

Switch:

x=5f^{-1}(x)+4

Subtract 4 from both sides:

x-4=5f^{-1}(x)

Divide both sides by 5:

f^{-1}(x)=\frac{x-4}{5}

And we're done :)
