Least to greatest 2/3, -2 2/5, 0.5, -0.8

Mathematics

Answer:

-2 2/5, -0.8, 0.5, 2/3

Step-by-step explanation:

We have four values, two that are fractions and two that are decimals and are asked to put them from least to greatest.

We have a dillema of values in this question, two are fractions and two are decimals. We need to convert all of them towards one symbol to get our answer.

Let's try decimals, since they are more easier to see which is the bigger value.

Start with 2/3, what is 2 divided by 3?

2/3

0.6 repeated.

As of now, we have 0.6 repeated, -2 2/5, 0.5, and -0.8.

Now do the second fraction, turn -2 2/5 to an improper fraction by multiplying the whole number by the denominator and adding the numerator.

-2 * 5 + 2

-10 + 2

-8/5

Now convert -8/5 to a decimal :

-8/5

-1.6

Now we have all decimals, put the from least to greatest.

0.6 repeated, -1.6, 0.5, -0.8

-1.6, -0.8, 0.5, 0.6 repeated

Therefore our list from least to greatest is :

-2 2/5, -0.8, 0.5, 2/3

Find the y-intercept of a line parallel to 8x – 2y = 12 and passes through the point (5, 3).
Dmitry_Shevchenko [17]

Answer:

-17

Step-by-step explanation:

8x -2y= 12

<em>Divide</em><em> </em><em>the</em><em> </em><em>whole</em><em> </em><em>equation</em><em> </em><em>by</em><em> </em><em>2</em><em>:</em>

4x -y= 6

<em>Rewrite the equation into the slope-intercept form (y=mx+c, where m is the gradient while c is the y-intercept).</em>

-y= -4x +6

y= 4x -6

Thus, gradient of given line= 4.

Since parallel lines have the same gradient, gradient of line= 4.

y= 4x +c

<em>To find the y-intercept of the lone, substitute a pair of coordinates.</em>

When x=5, y=3,

3= 4(5) +c

3= 20 +c

c= 3 -20

c= -17

Thus, the y-intercept of the line is -17.

The sum of two integers is 8 and their product is -20.<br>What are the integers?​
emmasim [6.3K]

Answer:

The answer to your question is

x = -2 and y = 10     or   x = 10 and y = -2

Step-by-step explanation:

          x + y = 8   (1)      from (1)    x = 8 - y

         xy = - 20    (2)

       

Solve them by substitution

      (8 - y) y = - 20

      8y - y² = -20

      y² - 8y - 20 = 0

   ( y - 10) (y + 2) = 0

    y - 10 = 0              and      y + 2 = 0

   <u> y1 = 10 </u>                               <u>y2 = -2</u>

 x1 = 8 - 10                             x2 = 8 - -2

 <u>x1 = -2</u>                                  <u> x2 = 10</u>
