Answer: a. 12.39, 12.62, 124, 124

Step-by-step explanation:

The given numbers are : 124, 12.62, 12.39, 124

By using decimals , we convert them into like decimals .

124.00, 12.62, 12.39, 124.00 (To two decimal places)

Now , Least number = 12.39 , Greatest number = 124.00 (Which is repeating)

In order from least to greatest : 12.39, 12.62, 124, 124.

Hence, the correct option is : a. 12.39, 12.62, 124, 124

The equation $x + {y = 2 can be rewritten in a form that reveals the y-intercept of the graph of the equatior

SSSSS [86.1K]

Answer:

$y = \frac{2}{z} - \frac{x}{z}$

Step-by-step explanation:

Given

$x + zy = 2$

Required

Rewrite to show y-intercept

We have: $x + zy = 2$

Subtract x from both sides

$zy = 2-x$

Divide both sides by z

$y = \frac{2}{z} - \frac{x}{z}$

<em>The y intercet is: </em> $\frac{2}{z}$ <em></em>

Given the two points (-1,-4) and (2,5): a. Find the slope between these two points

Dvinal [7]

Easy, using $\frac{y1-y2}{x1-x2}$ to find the intercept:

$\frac{-4-5}{-1-2}$ =

$\frac{-9}{-3}$ =3

This is your slope. m=3

To find y=mx+b form

-4=3(-1)+b

-4=-3+b

-1=b

y=3x-1 in y=mx+b form

find the x-intercepts of the parabola with vertex(6,27) and y-intercept (0,-81). write answer in form (x1,y1)(x2,y2). if necessa

sergey [27]

The vertex form of the equation is:
y = a ( x - h )² + k
- 81 = a ( 0 - 6 )² + 27
- 81 = 36 a + 27
- 108 = 36 a
a = - 108 : 36
a = - 3
y = - 3 ( x - 6 )² + 27
y = - 3 ( x² - 12 x + 36 ) + 27
y = - 3 x² + 36 x - 108 + 27
y = - 3 x² + 36 x - 81
y = - 3 ( x² - 12 x + 27 )
x² - 12 x + 27 = 0
x² - 9 x - 3 x + 27 = 0
x ( x - 9 ) - 3 ( x - 9 ) = 0
( x - 9 ) ( x - 3 ) = 0
x 1 = 3, x 2 = 9
Answer:
The x-intercepts are ( 3, 0 ) and ( 9, 0 ).
