HI PLEASE HELP ME QUICK I DON'T UNDERSTAND THIS

Here is a set of signed numbers: 7, -3, 1/2, -.8, .8, 1/10, -2
1) If their numbers represent temperatures in degrees Celsius, which is the coldest?

Answer:

2.55

Step-by-step explanation:

First take 11 and subtract it by 3 to get 8.

Then divide it by 3.14 and get 2.547770701...

After that round it to 2.55

It looks like the inequality is

[tex]\bigg|x + 6 - |3x + 6|\bigg| + |x + 2| - x - 4 \le 0[/tex]

or equivalently,

[tex]\bigg|x + 6 - 3 |x + 2|\bigg| + |x + 2| - x - 4 \le 0[/tex]

Recall the definition of absolute value:

[tex]|x| = \begin{cases} x & \text{if } x \ge 0 \\ -x & \text{if } x < 0 \end{cases}[/tex]

By this definition, we have

[tex]|x + 2| = \begin{cases} x + 2 & \text{if } x + 2 \ge 0 \\ -(x + 2) & \text{if } x + 2 < 0 \end{cases} = \begin{cases} x + 2 & \text{if } x \ge -2 \\ -x - 2 & \text{if } x < -2 \end{cases}[/tex]

Suppose [tex]x < -2[/tex]. Then

[tex]\bigg| x + 6 - |3x + 6| \bigg| + |x + 2| - x - 4 \\\\ = |x + 6 - 3 (-x - 2)| + (-x - 2) - x - 4 \\\\ = |4x + 12| - 2x - 6[/tex]

By definition of absolute value,

[tex]|4x + 12| = 4 |x + 3| = \begin{cases} 4x + 12 & \text{if } x \ge -3 \\ -4x - 12 & \text{if } x < -3 \end{cases}[/tex]

so we further suppose that [tex]x < -3[/tex]. Then

[tex]\bigg| x + 6 - |3x + 6| \bigg| + |x + 2| - x - 4 \\\\ = |4x + 12| - 2x - 6 \\\\ = (-4x - 12) - 2x - 6 \\\\ = -6x - 18 \le 0 \\\\ \implies x \ge -3[/tex]

but this is a contradiction, so this case gives no solution.

If instead we have [tex]-3 \le x < -2[/tex], then

[tex]\bigg| x + 6 - |3x + 6| \bigg| + |x + 2| - x - 4 \\\\ = |4x + 12| - 2x - 6 \\\\ = (4x + 12) - 2x - 6 \\\\ = 2x + 6 \le 0 \\\\ \implies x \le -3[/tex]

and [tex]-3 \le x[/tex] and [tex]x \le -3[/tex] means that [tex]\boxed{x = -3}[/tex].

Now suppose [tex]x \ge -2[/tex]. Then

[tex]\bigg| x + 6 - |3x + 6| \bigg| + |x + 2| - x - 4 \\\\ = |x + 6 - 3 (x + 2)| + (x + 2) - x - 4 \\\\ = |-2x| - 2 \\\\ = 2 |x| - 2[/tex]

If we further suppose that [tex]-2 \le x < 0[/tex], then

[tex]\bigg| x + 6 - |3x + 6| \bigg| + |x + 2| - x - 4 \\\\ = 2 |x| - 2 \\\\ = -2x - 2 \le 0 \\\\ \implies x \ge -1[/tex]

Otherwise, if [tex]x \ge 0[/tex], then

[tex]\bigg| x + 6 - |3x + 6| \bigg| + |x + 2| - x - 4 \\\\ = 2 |x| - 2 \\\\ = 2x - 2 \le 0 \\\\ \implies x \le 1[/tex]

Taken together, this case gives the solution [tex]\boxed{-1 \le x \le 1}[/tex]

So, the overall solution to the inequality is the set

[tex]\boxed{\left\{ x \in \mathbb R : x = -3 \text{ or } -1 \le x \le -1 \right\}}[/tex]

Answer:

3

Using the graph, it is found that:

a) The local minimum value of the function is of y = 0.

b) The values are x = -3, x = 3.

The local minimum of a function in a graph is the point at which the function changes from decreasing to increasing. In this problem, they are given by y = 0.

The values at which this happen is the values of x, that is, the horizontal axis. In this problem, they are at x = -3 and x = 3.

Based on Lauren's income and the various deductions, the net pay for April is $1,151.44.

Taxable income:

= Semimonthly income - 401k - Section 125 plan

= (51,680 / 24 pay periods) - (0.03 x 51,680/24 periods) - 139

= 2,153.33 - 64.6 - 139

= $1,949.73

= Taxable income - federal income tax - state income tax - social security - Medicare - advance repayment

= 1,949.73 - (1.6% x 1,949.73) - (5.25% x 1,949.73) - (6.2% x 2,153.33 gross income) - (1.45% x 2,153.33) - 500

= $1,151.44

A turning point is a point at which the derivative changes sign. A turning point may be either a relative maximum or a relative minimum (also known as local minimum and maximum). 

=====================================================

Work Shown:

A = P(consonant)

A = 3/4 since there are 3 consonants out of 4 letters in the word "SKIP".

B = P(even number)

B = 3/6

B = 1/2

P(consonant, even number) = A*B

P(consonant, even number) = (3/4)*(1/2)

P(consonant, even number) = 3/8

P(consonant, even number) = 0.375

Answer:

I counted 24.

Step-by-step explanation:

Its probably a trick question though

Answer: I counted 36.

(edit) But the answer is 40.

Step-by-step explanation:

Count all the "normal" squares. 16.

Then all the 2x2 normal squares. 9.

Then count all the tiny squares. 8.

Then the 2 big squares the tiny squares make. 2.

Then the giant square, which is all the squares. 1.

And I agree this probably is a trick question.

16 + 9 + 8 + 2 + 1 = 36 squares in total

*EDIT*

Apparently 3x3 squares exist so...

3x3 squares . 4

so 36 + 4 = 40 squares in total

(thanks to the person who asked the question in the first place for telling me about those 3x3 squares)

what did we learn in the other question ?

there are 8 equal sub-segments of 1/8 length between neighboring whole numbers.

so, each little line is 1/8.

the marker goes first to 1, and then one little line towards 2.

therefore, that number is 1 1/8.

Answer:

  x = {-9/4, 15/4}

Step-by-step explanation:

To use the square root property to solve the quadratic, you need to get it to a form where the square root function can be usefully applied. That will mean having a square of a binomial on one side of the equal sign, and a constant on the other side of the equal sign.

We can get that from the given equation by adding 5 to both sides.

  (x -3/4)^2 -5 = 4 . . . . . . given

  (x -3/4)^2 = 9 . . . . . . . add 5 to get the square by itself

  x -3/4 = ±3 . . . . . . . . . take the square root

  x = ±3 +3/4 = {-9/4, 15/4} . . . . add 3/4 and expand the result

Hey there!

10^2 + (3 + 5)^2 - 5

= 10 * 10 + (3 + 5)^2 - 5

= 100 + (8)^2 - 5

= 100 + (8 * 8) - 5

= 100 + 64 - 5

= 164 - 5

= 159

Therefore, your answer is: 159

Good luck on your assignment & enjoy your day!

Answer:

10² + (3 + 5)² - 5 = 159

Step-by-step explanation:

Given expression,

→ 10² + (3 + 5)² - 5

Evaluating the expression,

→ 10² + (3 + 5)² - 5

→ 10² + 8² - 5

→ 100 + 64 - 5

→ 100 + 59

→ 159

Hence, the answer is 159.

Hi! I hope you're enjoying your day!

First, 8 multiplied by 5 is equal to 40.

Then, 40 over 12 is the same as 40 divided by 12.

But hey! 40 isn't divisible by 12.

So we write this as a fraction:

[tex]\bold{\displaystyle\frac{40}{12} }[/tex]

Surprise! This fraction can be reduced.

[tex]\bold{\displaystyle\frac{10}{3} }[/tex]

Hence, the answer is:

[tex]\boxed{\boxed{\bold{\displaystyle\frac{10}{3} }}}[/tex] <-- the answer written as an improper fraction

[tex]\boxed{\boxed{\bold{3\displaystyle\frac{1}{3}}}}[/tex] <-- the answer written as a mixed number

Hope everything is clear.

Answer:

x = 5 ± i√11 / 2

Step-by-step explanation:

At the y-intercept the value of y is equal to 0.

=> 0 = x² + 5x + 9

=> x = -5 ± √25 - 4(9) / 2

=> x = 5 ± √-11 / 2

=> x = 5 ± i√11 / 2
