Answer:

y = 1

Step-by-step explanation:

Recognize that 25 and 125 are powers of 5 and rewrite the equation in terms of powers of 5.

The applicable rules of exponents are ...

(a^b)^c = a^(bc)

(a^b)/(a^c) = a^(b-c)

(a^b)(a^c) = a^(b+c)

Your equation can be written as ...

$25^4\div5^{5y}=125^y\\\\(5^2)^4\div5^{5y}=(5^3)^y\\\\5^{8-5y}=5^{3y}\\\\8-5y=3y\qquad\text{equate exponents of the same base}$

Now this can be solved as an ordinary linear equation.

8 = 8y . . . . . . add 5y to both sides

1 = y . . . . . . . divide by 8

The solution is y = 1.

The farmer brought 80 acorn squash to the market.

shepuryov [24]

The total number of acorn squash that the farmer brought to the market = 80
Percentage of acorn squash was less when the day ended = 35%
Then
The amount by which the
number of acorn squash decreased at the end of the day = (35/100) * 80
   = 280/10
   = 28
Then
The number of acorn squash left with the farmer = 80 - 28
   = 52
So from the above deduction, we can easily conclude that the farmer was left with 52 acorn squash at the end of the day.

The price of a technology stock was

Sindrei [870]

How you do this problem is that you first find out how much the price has gone down.

$9.82 - 9.73$

Then, you divide 9.82 by the answer to your previous equation and then you have completed the question!

The function f has a domain of {1, 3, 5, 7} and a range of {2, 4, 6}. Could f be represented by {(1, 2), (3, 4), (5, 6), (7, 2)}

bezimeni [28]

Answer:

Yes

Step-by-step explanation:

- Yes, a function with those domain and range values could certainly be represented by those points.

- (1,2) and (7,2) are points with separate domain values but identical range values: this is allowed because every x value is only assigned one y value (remember, one number x in domain cannot have two different numbers y in the range).

- Another way is the use of Vertical Line test of the curve passing through to the points {(1, 2), (3, 4), (5, 6), (7, 2)}. sketch down multiple vertical lines passing through the curve. If any particular vertical line intersects the curve at more than one point on the curve then the curve is not a function of y = f(x).

- You would see that all vertical lines are free this invalidation. Hence, y is a function of x having points {(1, 2), (3, 4), (5, 6), (7, 2)}.
