X = 10<br><br> x = 2<br><br> x = two divided by five.<br><br> x = 11
KengaRu [80]

Answer:

x = 10

Step-by-step explanation:

You can try the answers to see which works. (The first one does.)

Or, you can solve for the variable:

Divide by 75

... (1/5)^(x/5) = 3/75 = 1/25

Recognize that 25 = 5^2, so ...

... (1/5)^(x/5) = (1/5)^2

Equating exponents, you have

... x/5 = 2

... x = 10 . . . . . multiply by 5

_____

You can also start by taking logarithms:

... log(75) +(x/5)log(1/5) = log(3)

... (x/5)log(1/5) = log(3) -log(75) = log(3/75) = log(1/25) . . . . simplify the log

... x/5 = log(1/25)/log(1/5) = 2 . . . . . simplify (or evaluate) the log expression

... x = 10 . . . . . multiply by 5

_____

"Equating exponents" is essentially the same as taking logarithms.

Will mark brainliest Which table of ordered pairs represents a proportional relationship?
Flauer [41]

Answer:

2y = x, which is a proportional relationship.

Step-by-step explanation:

See the table attached.

The table gives the ordered pair represents a proportional relationship.

Take at least two pairs of the value of x and y.

Let they are (6,3) and (10,5).

Now, the equation for the straight line passing through the two points is given by  

\frac{y - 5}{5 - 3} = \frac{x - 10}{10 - 6}

⇒ 2(y - 5) = x - 10

⇒ 2y - 10 = x - 10

⇒ 2y = x

Hence, we can write x ∝ y and the constant of proportionality is 2. (Answer)
