Step-by-step explanation:

The value of x is -10. Steve made mistake in step 3 while transposing constant term and simplify.

The given equation is 8(2x + 7) = 6(x - 7) - 2.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solved as follows:

8(2x + 7) = 6(x - 7) - 2

⇒ 16x+56 = 6x-42-2

⇒ 16x+56 = 6x-44

⇒ 16x-6x = -44-56

⇒ 10x = -100

⇒ x = -10

Therefore, the value of x is -10. Steve made mistake in step 3 while transposing constant term and simplify.

Answer:

(5, 6)

Step-by-step explanation:

We can first find the midpoint by adding the two y values and dividing them by 2

3 + 9 = 12. 12/2 is 6. (2, 6) is the midpoint.

2 units to the right is on the x value, so 2+3 is 5. Put it all together and;

Step-by-step explanation:

Step 1: Define Equation

3.5(x + 12) = -2x + 18

Step 2: Solve for x

Answer:

The answer I arrived at was x = -4.364

Step-by-step explanation:

3.5(x + 12) = -2x + 18

=> multiply 3.5 by everything in parenthesis

3.5x + 42 = -2x + 18

=> subtract 18 from both sides

3.5x + 24 = -2x

=> subtract 3.5x from both sides

24 = -5.5x

=> divide both sides by -5.5

-4.364 = x

The matrix 3 x 8 is a full rank matrix.

Matrix:

Matrix are a set of numbers arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries, of the matrix.

Full rank matrix:

The rank of a matrix is the maximum number of its linearly independent rows.

Based on that, A full rank matrix is one which has linearly independent rows or/and linearly independent columns.

Given,

There is a matrix, which is 3x8, and 3 columns are linear dependent

Her we need to check whether the matrix is full rank or not.

We know that, the matrix is 3 x 8,

And 3 column are linear dependent,

Based on the following condition,

Answer:

5 hours

Step-by-step explanation:

Given

[tex]y = 420 + 72x[/tex] --- Revenue

[tex]y = 24x^2 + 180[/tex] --- Overhead cost

Required

Determine the hours for break even

To do this, we simply equate both expressions as follows:

[tex]24x^2 + 180 = 420 + 72x[/tex]

Collect Like Terms

[tex]24x^2 - 72x + 180 - 420 = 0[/tex]

[tex]24x^2 - 72x -240 = 0[/tex]

Divide through 24

[tex]x^2 - 3x - 10 = 0[/tex]

Expand:

[tex]x^2 -5x + 2x -10 = 0[/tex]

Factorize:

[tex]x(x -5) + 2(x -5) = 0[/tex]

[tex](x + 2)(x -5) = 0[/tex]

[tex]x + 2 = 0\ or\ x - 5 = 0[/tex]

[tex]x = -2\ or\ x = 5[/tex]

But x can't be negative because it represents time.

So, x = 5 hours

Answer:

The largest number of bundles he could create without any left over is 5.

Each bundle to contain 4 pencils, 16 pens and 11 markers

Step-by-step explanation:

Pencils = 20

Pens = 80

Markers = 55

a) What is the largest number of bundles he could create without any left over?

Find the highest common multiple of 20, 80 and 55

20 = 1, 2, 4, 5, 10, 20

80 = 1, 2, 4, 5, 8, 10, 16, 20......

55 = 1, 5, 11, 55

The highest common multiple of 20, 80 and 50 is 5

Pencils = 20 / 5

= 4

Pens = 80 / 5

= 16

Markers = 55 / 5

= 11

The largest number of bundles he could create without any left over is 5.

Each bundle to contain 4 pencils, 16 pens and 11 markers

Answer:

First and fourth statements are correct

Step-by-step explanation:

The function is [tex]|x+3|<5[/tex] where the domain is [tex]-8<x<2[/tex]

[tex]|-2+3|=1<5[/tex]

The first statement is correct.

[tex]|1+3|=4<5[/tex]

Substituting a value into the inequality from the solution set, such as 1, will create a false statement. This is wrong as it creates a true statement.

[tex]|4+3|=7\nless 5[/tex]

Substituting a value into the inequality not from the solution set, such as 4, will create a true statement. This is wrong as a value which is not from the solution set will create a false statement.

[tex]|6+3|=9\nless 5[/tex]

Substituting a value into the inequality not from the solution set, such as 6, will create a false statement. This is correct.

[tex]|10+3|=13\nless 5[/tex]

Substituting any value into the inequality will create a true statement. This is wrong as the value of x must be in the solution set.

Answer:

1.) Substituting a value into the inequality from the solution set, such as –2, will create a true statement.

4.) Substituting a value into the inequality not from the solution set, such as 6, will create a false statement.

[tex]\frac{x}{3}+10=x+2[/tex]

Multiply whole equation by 3 to get ride of the denominator.

[tex]\frac{x}{3}(3)+10(3)=x(3)+2(3)\\x+30=3x+6[/tex]

[tex]30-6=3x-x[/tex]

Move x to the another side and subtract as 6 to another side and subtract.

[tex]24=2x[/tex]

Then we move 2 to divide 24.

[tex]\frac{24}{2}=x\\x=12[/tex]

Therefore, the answer is x = 12.

Answer:

Fraction: x= 4/5

Decimal: x= 0.8

Answer:

x = -2, y = -9

Step-by-step explanation:

You can substitute the value of y into y. The first equation shows that y is equal to 4x -1, so we can switch this with the y in the second equation.

y = 2x -5 will become

4x - 1 = 2x - 5

Add 5 to both sides

4x + 4 = 2x

Subtract 4x from both sides

4 = -2x

Divide both sides by -2

-2 = x

Now we plug this number into an equation to find y.

y = 4x - 1 becomes

y = 4(-2) - 1

Simplifying it, we have:

y = -8 - 1

y = -9
