Find the slope of the line that contains (3,-5) and (5,5)

3241004551 [841]

slope (M) = (y2-y1)/(x2-x1)

x1 =3, y1= -5, x2 = 5, y2=5

= (-5-5) / (3-5) = -10/-2 = 5

M=5

Solve the equation by completing the square. Round to the nearest hundredth if necessary. x2 – 5x = 12

GuDViN [60]

X^2 - 5x = 12
x^2 - 5x + 6.25 = 12 + 6.25
(x - 2.5)^2 = 18.25
x - 2.5 = (+-) sqrt 18.25
x = 2.5 (+ - ) 4.27

x = 2.5 + 4.27 = 6.77 <==
x = 2.5 - 4.27 = -1.77 <==

Which set of rational numbers is arranged from least to greatest? 1 over 5, −1.4, negative 1 over 2, 3 3, negative 1 over 2, −1.

Mars2501 [29]

Answer:

Option 4 - $-1.4,\ -\frac{1}{2},\ \frac{1}{5},\ 3$

Step-by-step explanation:

To find : Which set of rational numbers is arranged from least to greatest?

Solution :

The set of rational numbers are

$3,\ \frac{1}{5},\ -1.4,\ -\frac{1}{2}$

Writing all number in one form,

$\frac{1}{5}=0.2$

$-\frac{1}{2}=-0.5$

Now, -1.4<-0.5<0.2<3

From least to greatest the set of natural numbers are

$-1.4$

So, $-1.4,\ -\frac{1}{2},\ \frac{1}{5},\ 3$

Therefore, option 4 is correct.
