Answer:

Step-by-step explanation:

-8x + 14 = -2(4x - 7)

use the distributive property to get rid of the parentheses (-2 x 4x and -2 x -7) (negative times negative equals positive)

-8x + 14 = -4x + 14

subtract 14 on both sides to cancel out 14

-8x is not equal to -4x

although this may seem like a weird answer, if x is the same variable (pretend it's one) 1 multiplied with -8 will not equal 1 multiplied with -4

Answer:

all real numbers

Step-by-step explanation:

Given

- 8x + 14 = - 2(4x - 7) ← distribute parenthesis

- 8x + 14 = - 8x + 14

Since both sides are equal, then any real value of x is a solution of the equation.

Step-by-step explanation:

The formula is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. Here, we can plug in values where x2 = -6, x1 = -4, y2=-4, and y1 = 7. Solving, we get the slope is 11/2 or 5.5.

Answer:

x=15

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

9x−38+4x+23=180

9x+−38+4x+23=180

(9x+4x)+(−38+23)=180(Combine Like Terms)

13x+−15=180

13x−15=180

Step 2: Add 15 to both sides.

13x−15+15=180+15

13x=195

Step 3: Divide both sides by 13.

13x/13=195/13

Answer:

15

Step-by-step explanation:

9x-38+4+23=180

13x-15=180

13x=195

x=15

Answer:

 [tex]\frac{1}{3}[/tex]n  + 4  = 6  

6

Step-by-step explanation:

Given problem:

      4 more than one third of a number n is 6

Unknown:

The equation = ?

Solution of the number  = ?

Solution:

 let the number  = n

So, 4 more than one third of a number;

  One third of n = [tex]\frac{1}{3}[/tex]n

  4 more;

                [tex]\frac{1}{3}[/tex]n  + 4

   is 6;

             [tex]\frac{1}{3}[/tex]n  + 4  = 6   (equation of the expression)

Let us now solve the equation:

                         [tex]\frac{1}{3}[/tex]n  + 4  = 6  

                    [tex]\frac{1}{3}[/tex]n = 6 - 4

                   [tex]\frac{1}{3}[/tex]n = 2

                     n = 6

Which symbol completes the inequality represented on the graph?

     z _____ 1.5

>

Greater-than-or-equal-to

<

Less-than-or-equal-to

The required inequality is given as  Z Greater than or equal(≥) to 1.5.

Number line from -3 to 5 is given and a open circle at 1.5.
Right of the circle is shaded and the inequality for the shaded portion to be determine.

Inequality is when the equations contain [≤ , ≥ <, >] is termed as inequalities.

Here, in the given numerical shaded potion of Z is beyond 1.5 to the right so their must be an greater than equal to (≥) after z. i.e. z ≥ 1.5.

Thus,  the required inequality is given as  Z Greater than or equal(≥) to 1.5.

Answer:

The answer is "[tex]0.375 \ m^2 \ \ and \ \ 0.1875 \ m^2[/tex]".

Step-by-step explanation:

A rectangular paper on the side is given by Olivia:  

[tex]a= \frac{1}{2} \ m \\\\b= \frac{3}{4} \ m[/tex]

On the diagonal she cuts paper. A paper parts which results would be about half the original field.  

Area of origin:

[tex]A= a\times b[/tex]

   [tex]= \frac{1}{2} \times \frac{3}{4} \\\\= \frac{3}{8} \ m^2\\\\ = 0.375 \ m^2[/tex]

The resulting parts area:  

[tex]A_2 =\frac{A}{2} = \frac{\frac{3}{8}}{2}[/tex]

             [tex]=\frac{3}{16} \ m^2 \\\\= 0.1875 \ m^2[/tex]

Given:

Maria makes $6.00 an hour plus 5% commission for telephone sales.

Working time = 8 hours

Sales = $600.00.

To find:

The amount that Maria make yesterday.

Solution:

We know that,

1 hour = $6.00

8 hour = 8 × $6.00 = $48.00

Commission = 5% of telephone sales

Sales = $600.00.

[tex]Commission=5\times 6[/tex]

[tex]Commission=30[/tex]

Total amount that Maria make yesterday is the sum of total hourly changes plus commission.

[tex]\$48.00+\$30.00=\$78.00[/tex]

Therefore, the required amount is $78.00.
