For each ordered pair, determine whether it is a solution to 3x-5y=-13

If √x=9 then the value of x is 81.

Two or more expressions with an Equal sign is called as Equation.

The given equation is √x=9

Square root of x is equal to nine.

We need to find the value of x.

√x=9

Apply square on both sides

(√x)²=9²

The root and square will be cancelled on the left side

x=9²

Nine to the power of 2 is eighty one

x=81

Hence, the value of x is 81 when √x=9

Step-by-step explanation:

C. i) y = 23,000(1 - 0.15)^t

ii) y = 23,000(1 - 0.15)^t

y = 23,000 x 0.85^4

y = 23,000 x 0.52200625

y = $12,006.14

y = $12,006. when rounded to the nearest dollar

Step-by-step explanation:

3x² - 18x + 5 = 47 ( subtract 5 from both sides )

3x² - 18x = 42 ( divide through by 3 )

x² - 6x = 14

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 3)x + 9 = 14 + 9

(x - 3)² = 23 ( take square root of both sides )

x - 3 = ± [tex]\sqrt{23}[/tex] ( add 3 to both sides )

x = 3 ± [tex]\sqrt{23}[/tex]

If a bag has 30 orange marbles then that means it has 42 red marbles

Step-by-step explanation:

If there are 7 red marbles for every 5 orange marbles then what you would do is.

30/5=6

6*7=42

Each marble bag sold by Chris's marbles company contains 7 red marbles for every 5 orange marbles , if a bag had 30 orange marbles Then the bag contains 42 red marbles.

In the problem, we are given that each bag of marbles contains 7 red marbles for every 5 orange marbles. We need to find the number of red marbles when there are 30 orange marbles in the bag.

Let's represent the number of red marbles as R and the number of orange marbles as O.

According to the information provided, we have the following relationship:

R / O = 7 / 5

Now, we are given that the number of orange marbles (O) in the bag is 30. We can substitute this value into the equation:

R / 30 = 7 / 5

To find the number of red marbles (R), we can cross-multiple

R = (7 / 5) * 30

R = 42

Therefore, the bag contains 42 red marbles.

In summary, we used the given ratio of red to orange marbles in the bag to set up a proportion and then solved for the number of red marbles when the number of orange marbles was known. This allowed us to find that there are 42 red marbles in the bag.
