egoroff_w [7]

Answer:

60 stores

Step-by-step explanation:

Here, we want to get the total number of stores in which Esther and her 6 brothers went shopping

From the question, she shopped in 12 different stores

Each of her six brothers shopped in 8 different stores

That makes the number of stores in which the brothers shop be 8 * 6 = 48 stores

The total number of stores is thus, 48 + 12 = 60 stores

=3k+2.

Therefore, the given system of equations will have infinitely many solutions, if

k+2

⇒

k+2

=

3k+2

4

⇒k+2=4 and 3k+2=8

⇒k=2 and k=2

⇒k=2

Hence, the given system of equations will have infinitely many solutions, if k=2.

The first three steps for solving the quadratic equation by completing the square are shown. Fill in the missing number in the l

Oksi-84 [34.3K]

The first three steps for solving the quadratic equation by completing the square are as follows;

1. $\rm 9x^2 +54x = 7$

2. $\rm 9(x^2 + 6x) = 7$

3. $\rm 9(x^2 + 6x + 9) = 7 + 81$

Given

The quadratic equation given as 9x^2 + 54x = 7.

<h3>Quadratic equation;</h3>

The highest power of the degree is 2 is known as a quadratic equation.

To solve using the completing the square method.

The first three steps for solving the quadratic equation by completing the square are given below.

1. Write the equation in a way that the constants are on the right side while the terms with x are on the left.

$\rm 9x^2 +54x = 7$

2. Make sure that the coefficient of the x^2 term is 1.

$\rm 9(x^2 + 6x) = 7$

3. Adding a term to both sides that will complete the square on the left side.

This is done by dividing the coefficient of the x term by 2 and squaring it.

The same amount should be added to the right side to balance the equation.

$\rm 9(x^2 + 6x + 9) = 7 + 81$
