Answer:

10%

12.5%

13%

19%

Step-by-step explanation:

First write all of the amounts as a percent.

1/8 = 12.5%

13%

.10 = 10%

19%

Then you can order them from least to greatest.

10%, 12.5%, 13%, and then 19%

hope this helps

Write the equation of a line:
yawa3891 [41]

a)    Line parallel to the line 3x+5y=-10 is -6x-10y=9

b)    Line parallel to the line 2y-4x=5 and which goes through the point

       (3,7) is y= 2x-1.

c)      Line perpendicular to the line 8x+6y=-1 and which goes through the

        point (-2,1) is 4y= 3x+ 10


<h3>What is equation of line?</h3>

The standard form of equation of a line is ax + by + c = 0. Here a, b, are the coefficients, x, y are the variables, and c is the constant term. It is an equation of degree one, with variables x and y.

a) Equation parallel to 3x+5y=-10 is

    -6x-10y=9

So, it satisfies:  \frac{a_1}{a_2} = \frac{b_1}{b_2} \neq \frac{c_1}{c_2}

b)given equation into the form of y=mx+c,

     2y-4x=5

we can find the gradient of the line.

  2y= 5+4x

  y= \frac{5}{2} + 2x

Hence, the gradient is 2.

As, Parallel lines have the same gradient

Thus the line would also have a gradient of 2.

Substitute m=2 into the equation:

y= 2x +c

To find the value of c, substitute a pair of coordinates.

When x=3, y=7,

7= 2(3) +c

7= 6 +c

c=6-7

c= -1

So, equation of line be: y= 2x-1.

c) Given: 8x+6y=-1

     6y= -1-8x

     y= \frac{-1}{6} -\frac{4}{3}x

Hence, m= -\frac{4}{3}

We know, if two lines are perpendicular have m and m' as slope then,

m*m'=-1

\frac{-4}{3} *m'=-1

 m'= \frac{3}{4}

Now, y= \frac{3}{4} x +c

   

Put x= -1 and y=1

then, 1= \frac{3}{4} (-2) + c

         c= \frac{5}{3}

So,  y= \frac{3}{4} x + \frac{5}{2}

     4y= 3x+ 10

What number must you add to the polynomial below to complete the square?<br><br> x2 + 15x
Aleksandr-060686 [28]

Answer:

The number \frac{225}{4} is added to the polynomial below to complete the square.

Step-by-step explanation:

Perfect square binomial:

A perfect square binomial is given by:

(a + b)^2 = a^2 + 2ab + b^2

In this question:

We have that:

a^2 + 2ab + b^2 = x^2 + 15x + ?

Since a = x, we have that:

2ab = 15x

2b = 15

b = \frac{15}{2}

Completing the square:

The term that completes the square is b^2. So

b^2 = (\frac{15}{2})^2 = \frac{225}{4}

The number \frac{225}{4} is added to the polynomial below to complete the square.
