Answer:

The first option

Step-by-step explanation:

First, we can convert all of the numbers to decimal from (it will be easier to understand that way).

$\pi = 3.14\\\\\sqrt{8} = 2.82\\\frac{\sqrt{2} }{4} =.353$

Now, we can easily see which numbers are bigger/smaller.

Help with this short answer.

timurjin [86]

Start by solving inside the parentheses. According to PEMDAS you will divide 10 and 2 first. Divide 10 by 2 and you will have: 8 + (5)(4) - (6 + 5) + 44.

Now finish solving inside the parentheses and add 6 and 5.

8 + (5)(4) - (11) + 44, multiply 5 and 4.

8 + 20 - 11 + 44, then solve from left to right.

61 is the answer.

Determine the equation of the linear function that has a slope of -4 and passes through the point (2,-4). Write the equation in

padilas [110]

Answer:

Part 1) $y=-4x+4$

Part 2) The graph in the attached figure

Step-by-step explanation:

Part 1)

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=-4\\point\ (2,-4)$

substitute in the linear equation

$-4=-4(2)+b$

solve for b

$-4=-8+b\\b=8-4\\b=4$

substitute

$y=-4x+4$

Part 2) Draw the equation

we know that

To graph a line we need two points

we have the y-intercept (0,4) and (2,-4)

Plot the points, connect them and join to draw the line

The graph below shows the solution set of which inequality?

GrogVix [38]

Answer:

The answer is the option D

$x^{2} > 4$

Step-by-step explanation:

we know that

The inequality

$x^{2} > 4$

has two solutions

<u>First solution</u>

$x > 2$

The solution is the interval-------> (2,∞)

All real numbers greater than $2$

<u>Second solution</u>

$-x > 2$ ------> $x < -2$ -

The solution is the interval-------> (-∞,-2)

All real numbers less than $-2$
