Answer:

k=-2

Step-by-step explanation:

Let's write the left hand side as a negative power, and 9 as a power of 3:

3^-^k=3^2 At this point, for the equality to still stand, the exponents have to be equal:

-k = 2 \rightarrow k=-2

Which shows solutions to X+4y=9 if X and y must be whole numbers? A. {(0,9)(1,5)(2,1)} B.{(2,1)(1,6)(0,9)} C.{(1,2)(5,1)(9,0) D.
Dafna11 [192]
The answer here is C. Let's proof.

Since we are dealing with whole numbers, select a constant for x to satisfy that y will result a whole number.
If x = 1, then the function would be 1 + 4y = 9. Solving for y,
4y = 9 - 1
4y = 8
y = 2
In ordered pair, that is (1,2)

Next, if x = 5, then 5 + 4y = 9. Solving for y,
4y = 9 - 5
4y = 4
y = 1
In ordered pair, that is (5,1).

Lastly, if x = 9, then 9 + 4y = 9. Solving for y,
4y = 9 - 9
y = 0/4
y = 0
In order pair, that is (9,0).

A game decreased in price by 2/3. After the reduction it was priced at £13. What was the original price of the game?​
Archy [21]

Answer:

x = 39

Step-by-step explanation:

Based on the given conditions, write: x=\frac{13}{1-\frac{2}{3}}

Find common denominator and write numerators above common denominator: x=\frac{\frac{13}{3-2} }{3}

Calculate the sum or difference: x=\frac{\frac{13}{1} }{3}

Divide the fraction by multiplying its reciprocal: x=13*3

Calculate the product or quotient: x=39

Answer: x=39
