Answer:

All integers greater than 4 (5 or greater) and less than -4 (-5 or less)

Step-by-step explanation:

x² + bx + 5

b² - 4ac 》 0

b² - 4(1)(5) 》 0

b² - 20 》 0

b 》 sqrt(20)

b 》 4.47

b 《 -sqrt(20)

b 《 - 4.47

All integers greater than 4 (5 or greater) and less than -4 (-5 or less)

Help!!! ---- The graph of a function is a line that passes through the points (1,4), (3,8), and (6,y). What is the value of y?

natima [27]

Answer:

y = 14

Step-by-step explanation:

First find the slope of the line. To find the slope of the line, use the slope formula:

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{8-4}{3-1} =\frac{4}{2}=2$

The slope of the line is 2.

Repeat this same process instead with points (1,4) and (6,y). Substitute m = 2.

$2 = \frac{y-4}{6-1} \\\\ 2=\frac{y-4}{5}\\\\ 10=y-4\\\\14b= y$

So y = 14.

Paul bought 2.25 meters of wood to make 5 shelves of equal length . What is the length of each shelf ? show your work on a picec

LiRa [457]

Answer:

Length of each shelf is 0.45 meters

Step-by-step explanation:

Given

$Total\ Length = 2.25\ meters$

$Shelves = 5$

Required

Determine the length of each shelf

This is calculated by dividing the total length by number of shelves as thus:

$Length = Total\ Length/Number\ of\ Shelf$

$Length = 2.25m /5$

$Length = 0.45m$

Hence;

<em>Length of each shelf is 0.45 meters</em>

What is the missing coefficient of the x-term of the product (-x-5)² after it has been simplified?

Mice21 [21]

The missing coefficient of the x-term after finding the product of (-x - 5)², is: C. 10.

<h3>What is the Coefficient of a Variable?</h3>

The coefficient of a variable is the numerical value that comes before the variable and multiplies it.

Find the product of (-x - 5)²:

(-x - 5)(-x - 5)

-x(-x - 5) -5(-x - 5)

x² + 5x + 5x + 25

x² + 10x + 25

The x-term is "10x". The coefficient is: 10.
