-  \frac{36 + 4}{9}  \times  \frac{3}{10}
-  \frac{40}{9}  \times  \frac{3}{10}
-  \frac{120}{90}
-  \frac{4}{3}  \: or \:  - 1 \frac{1}{3}

E. fill -2(2/3) for W
- 3 \frac{1}{8} ( - 2 \frac{2}{3} )
\frac{ - 24 + 1}{8}  \times  \frac{ - (6 + 2)}{3}
- \frac{25}{8}  \times  \frac{ - 8}{3}
-  \frac{ - 200}{24}
\frac{25}{3}  \: or \: 8 \frac{1}{3}
F. fill (-3/4)
((\frac{3}{8} )( \frac{ - 3}{4} )) + (( \frac{1}{8} )( \frac{ - 3}{4} ))
\frac{3  \times   - 3}{8 \times 4} +  \frac{1 \times  - 3}{8 \times 4}
- \frac{9}{32}   -  \frac{3}{32}
- \frac{12}{32}  =   - \frac{3}{8}

dezoksy [38]

Answer:

She worked for x hours this week.

Unfortunately, she was charged $15 for a late delivery on Tuesday

She was supposed to earn $12 × x = $12x this week

But she was charged $15 for late delivery on Tuesday

So her net earning this week is; $12x - $15

The solutions for the quadratic equation are given as follows:

x = -1, x = 7/5

<h3>What is a quadratic function?</h3>

A quadratic function is given according to the following rule:

y = ax^2 + bx + c

The solutions are:

  • x_1 = \frac{-b + \sqrt{\Delta}}{2a}
  • x_2 = \frac{-b - \sqrt{\Delta}}{2a}

In which:

\Delta = b^2 - 4ac

For this problem, the equation is:

5x² - 2x - 7 = 0.

Hence the coefficients are a = 5, b = -2 and c = -7, and then the solutions are found as follows:

  • \Delta = (-2)^2 - 4(5)(7) = 144
  • x_1 = \frac{2 + \sqrt{144}}{10} = \frac{7}{5}
  • x_2 = \frac{2 - \sqrt{144}}{10} = -1

The solutions are:

x = -1, x = 7/5

xeze [42]

Answer:

D. x-\frac{5}{2}y =  \frac{25}{2}

Step-by-step explanation:

Given

y = \frac{2}{5}x - 5

Required

Determine its equivalent

<em>From the list of given options, the correct answer is</em>

x - \frac{5}{2}y = \frac{25}{2}

This is shown as follows;

y = \frac{2}{5}x - 5

Multiply both sides by \frac{5}{2}

\frac{5}{2} * y = \frac{5}{2} * (\frac{2}{5}x - 5)

Open Bracket

\frac{5}{2} * y = \frac{5}{2} * \frac{2}{5}x - \frac{5}{2} *5

\frac{5}{2}y = x - \frac{25}{2}

Subtract x from both sides

\frac{5}{2}y - x = x -x - \frac{25}{2}

\frac{5}{2}y - x = - \frac{25}{2}

Multiply both sides by -1

-1 * \frac{5}{2}y - x * -1 = - \frac{25}{2} * -1

-\frac{5}{2}y + x =  \frac{25}{2}

Reorder

x-\frac{5}{2}y =  \frac{25}{2}

<em>Hence, the correct option is D</em>

x-\frac{5}{2}y =  \frac{25}{2}
