We have the equation of the line as : 4x+2y=12

Please help me. I've been working on this for an hour and I just need an answer. Thank you so much if you do all of these. I will forever be indebted to you :)

Part A:

Rewrite without absolute value for the given conditions:

1) y = |x−3|+|x+2|−|x−5|, if x > 5

2) y = |10-x|, if x<10

Part B:

Write the absolute value equations in the form x−b=c (where b is a number and c can be either number or an expression) that have the following solution sets:

1) All numbers such that x≤5.

2) All numbers such that x≤−14.

Again, thank you so much if you do all of these!

Answers

Answer:

Step-by-step explanation:

Rewrite without absolute value for the given conditions:

1) y = |x−3|+|x+2|−|x−5|, if x > 5

y = x-3 + x + 2 - (x-5)

y = x + 4

2) y = |10-x|, if x<10

y = 10 - x

In both cases, the value of x is held to values that make the absolute value notation redundant, so they can be removed.

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

Write the absolute value equations in the form x−b=c (where b is a number and c can be either number or an expression) that have the following solution sets:

I actually don't understand the question. Rewrite the above equations, or make new ones? Sorry.

1) All numbers such that x≤5

x≤5 kinda does it for me. X can be any number less than or equal to 5. Ta da. (?)

2) All numbers such that x≤−14.

x ≤ -14

The mean can be found when you add all the numbers in a set, and then divide that sum by the amount of numbers given. Find the average tree growth of four Douglas Fir trees: 2.2 in., 1 1/5 in., and 1 1/2 in.​

Answers

Answer:

49/30

Step-by-step explanation:

To find the mean, add up 2.2 + 1 1/5 + 1 1/2 to get 49/10

Then divide that by 3 (it says four Douglas trees but you only put 3 types)

49/10 divided by 3 is 49/10 times 1/3, which is 49/30

-15 = -5x - Subtract -8 from both sides

3 = x - Divide both sides of the equation by -5

In 3 hours the temperature will be -7°.

For what value of c does x^2−2x−c=4 have exactly one real solution?
PLEASE HELP!!!!!!!

Answers

Answer:

-5

Step-by-step explanation:

Moving all terms of the quadratic to one side, we have

[tex]x^2-2x-(c+4)=0[/tex].

A quadratic has one real solution when the discriminant is equal to 0. In a quadratic [tex]ax^2+bx+d[/tex], the discriminant is [tex]\sqrt{b^2-4ad}[/tex].

(The discriminant is more commonly known as [tex]\sqrt{b^2-4ac}[/tex], but I changed the variable since we already have a [tex]c[/tex] in the quadratic given.)

In the quadratic above, we have [tex]a=1[/tex], [tex]b=-2[/tex], and [tex]d=-(c+4)[/tex]. Plugging this into the formula for the discriminant, we have

[tex]\sqrt{(-2)^2-4(1)(-(c+4))[/tex].

Using the distributive property to expand and simplifying, the expression becomes

[tex]\sqrt{4-4(-c-4)}=\sqrt{4+4c+16}\\~~~~~~~~~~~~~~~~~~~~~~=\sqrt{20+4c}\\~~~~~~~~~~~~~~~~~~~~~~=\sqrt{4}\cdot\sqrt{5+c}\\~~~~~~~~~~~~~~~~~~~~~~=2\sqrt{c+5}.[/tex]

Setting the discriminant equal to 0 gives

[tex]2\sqrt{c+5}=0[/tex].

We can then solve the equation as usual: first, divide by 2 on both sides:

[tex]\sqrt{c+5}=0[/tex].

Squaring both sides gives

[tex]c+5=0[/tex],

and subtracting 5 from both sides, we have

[tex]\boxed{c=-5}.[/tex]

The company makes a single serving cereal box that contains a volume of 1.2 ounces of cereal. They plan to make an extra large box for school cafeterias. The extra large box will be a dilation of the single serving box using a scale factor of 9/2
. How many ounces of cereal will the extra large box contain?

Answers

Answer:

109.35 ounces

Step-by-step explanation:

The scale factor is a linear scale factor.

The box is a three-dimensional solid, so the length, width, and height will be dilated by a factor of 9/2.

The volume factor is (9/2)³ = (4.5)³ = 91.125

The number of ounces is proportional to the volume.

1.2 ounces × 91.125 = 109.35 ounces

Problem 5

Answer: 300 square inches

------------------

Work Shown:

a = 15

b = unknown

c = 25

a^2 + b^2 = c^2

15^2 + b^2 = 25^2

225 + b^2 = 625

b^2 = 625 - 225

b^2 = 400

b = sqrt(400)

b = 20

The rectangle is a = 15 by b = 20 to get an area of ab = 15*20 = 300 square inches.

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

Problem 6

Answer:

Part A) The area = 48 square inchesPart B) The area = 16*sqrt(2) square inches

------------------

Work Shown:

Part A)

area = base*height/2

area = 8*12/2

area = 96/2

area = 48

Part B)

a^2 + b^2 = c^2

8^2 + b^2 = 12^2

64 + b^2 = 144

b^2 = 144 - 64

b^2 = 80

b = sqrt(80)

b = sqrt(16*5)

b = sqrt(16)*sqrt(5)

b = 4*sqrt(5)

Therefore,

area = base*height/2

area = a*b/2

area = 8*4*sqrt(5)/2

area = 16*sqrt(2)

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

Problem 7

Answer: 36 cm

------------------

Work Shown:

area = 81

area = x^2

x^2 = 81

x = sqrt(81)

x = 9

The side lengths of the square are 9 cm each.

P = perimeter

P = 4x

P = 4*9

P = 36

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

Problem 8

Answer: 12.5*sqrt(15)

------------------

Work Shown:

The horizontal base of 10 is cut in half to get 5.

a = 5 = horizontal side

b = unknown height

c = 20 = hypotenuse

a^2 + b^2 = c^2

5^2 + b^2 = 20^2

25 + b^2 = 400

b^2 = 400 - 25

b^2 = 375

b = sqrt(375)

b = sqrt(25*15)

b = sqrt(25)*sqrt(15)

b = 5*sqrt(15)

area = base*height/2

area = a*b/2

area = 5*5*sqrt(15)/2

area = 12.5*sqrt(15)

Consider these scenarios. 1. An elephant weighs 1. 5 × 104 units. 2. A mouse weighs 2. 13 × 10-5 units. 3. A puppy weighs 1. 2 × 102 units. Determine the unit of measurement that best represents each scenario. 1. 2. 3.

Answers

An ounce unit will best represent each scenario.

The average weight of an elephant is around 3000-4000 kg.

The average weight of a mouse = 15-20 grams

The average weight of a puppy = 25-30kg

It is given that

Weight of the elephant = [tex]1.5 * 10^5[/tex] units ≈150000 units

Weight of the mouse = [tex]6.3*10^2[/tex] units ≈630 units

Weight of the puppy = [tex]1.2*10^3[/tex] units ≈1200 units

What is the relation between an ounce and a kg?

1 ounce = 0.0253495 kg

150000 ounces = 3800kg, near to actual value

630 ounces = 16kg, near to actual value

1200 ounces = 30kg, near to actual value

Therefore, an ounce unit will best represent each scenario.
