The Simplest form is \frac{1}{2}


\frac{1}{4} +4(\frac{1}{2} - \frac{3}{4})^{2}   PEMDAS

\frac{1}{4}+4(-\frac{1}{4})^{2}                       Subtract inside parenthesis \frac{1}{2} - \frac{3}{4} =- \frac{1}{4}

\frac{1}{4}+4( \frac{1}{16})                            Square - \frac{1}{4}                       

\frac{1}{4} + \frac{1}{4}                                 Multiply 4 and \frac{1}{16}                        

\frac{1}{2}                                                       Add \frac{1}{4} + \frac{1}{4}

The original price was $20,000 the sales price was $18,000 what is the percent discount
lord [1]

Answer:

10 percent :)

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 20000 × 10/100

Discount = 20000 x 0.1

You save = $2,000.00

Final Price = Original Price - Discount

Final Price = 20000 - 2000

Final Price = $18,000.00

i hope this helps! pls stay happy and healthy, friend! :))

grigory [225]

Answer:

25%

Step-by-step explanation:

Given parameters:

Amount earned by Jessica per month = 800

Total savings target per year  = 2400

Unknown:

Percentage of savings = ?

Solution:

The total earning per year will be the amount earned per month multiplied by the total number months;

 Amount earned in a year = 12 x 800  = 9600

Let the percentage of savings per year  = y%

  Now;

              2400 = \frac{y}{100} x 9600

                  y = 25%

Please help I asked this question earlier and nobody answered! :(​
tatiyna

Answer:

B

Step-by-step explanation:

One way to tell is to put both equations into slope-intercept form.  That form is usually written y=mx+b where  <em>m</em>  is the slope and  <em>b</em>  is the y-intercept.

Solve the first equation for y.

6x+2y=5 \\ 2y=-6x+5 \\ y=-3x+5/2

The slope of this line is -3, and its y-intercept is 5/2.

Solve the second equation for y.

y+3x=2\\y=-3x+2

The slope of this line is -3 and its y-intercept is 2.

The lines are parallel because they have the same slope and <u>different</u> y-intercepts.  There is no solution to the system.
