Answer:

9) y=(-6-3x)/2                 10) y=(2x+15)/3            11) y=8+4x

12) y=1/2x+6                   13) y= (8-3x)/-4            14) y= (10-6x)/-2

Step-by-step explanation:

The methods I used are known as float and ping, and escalator:

9) We can float the 3x to the other side to make

2y=-6-3x

We now escalate the 2 down to make:

y= [tex]\frac{-6-3x}{2}[/tex]

10) We simply escalate the 3 down to give:

y= [tex]\frac{2x+15}{3}[/tex]

11) We simply float the -4x to the other side:

y=8+4x

12) For this question, it will be better to expand the bracket first:

y-8=-1/2x-2

Now we float the -8 to the other side to give:

y=-1/2x-2+8

Which can be simplified to give:

y=1/2x+6

13) We simply float the 3x to the other side to give:

-4y=8-3x

Now we escalate the -4 down to give:

y= [tex]\frac{(8-3x)}{-4}[/tex]  
14) We float the 6x to the other side to give:

-2y=10-6x

Now we escalate the -2 down to give:

y= [tex]\frac{10-6x}{-2}[/tex]

the answer will be

48$ dollars

Answer:

20 + 6x

$44

Step-by-step explanation:

So 5 CD's for 20 dollars is $4 ea. then each one added will be +6 with the variable (x).

so you can't have the first 5 becuase x is used for every one OVER 5.

So

$ or price = 20 + 6x

plug 4 in because 9-5 = 4

20 + 6(4)

20 + 24

$44

Answer:

40%

Step-by-step explanation:

Flips 600 times, that's the total flips. ###/600

Heads flipped 240 times, and that's what you're looking for. 240/600

240/600 simplified is 2/5 (0.4)

You're looking for a frequency/percentage so you're looking at the decimal

Decimal number = Percentage

So it'll be 40%

Step-by-step explanation:

6 x 14 = 84. 84 divided by 2 = 42.

a = b x h divided by 2

Answer: 7

Step-by-step explanation:

Let the unknown length be x

Cut the polygon into 2 pieces

6 * 24 + x * (18 - 6) = 228

144 + 12x = 228

12x = 84

x = 7

The length of the side labeled with a question mark in the given polygon is 7 meters.

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

Given that, the area of this polygon is 228 square meters.

We know that, the area of a rectangle is Length×Breadth

Area of a large rectangle = 24×6

= 144 square meters

Let the length of unknown side be x.

Area of a small rectangle = 12×x

Total area = Area of a large rectangle+Area of a small rectangle

228=144+12x

12x=228-144

12x=84

x=84/12

x=7 meters

Therefore, the length of the side labeled with a question mark is 7 meters.

Answer:

D. Subtraction Property of Equality

Step-by-step explanation:

D. Subtraction Property of Equality

From 6-7, you subtract 132 from both sides. You can only do this because of the subtraction property of equality which essentially means that if you subtract something from one side of the equation, you also have to subtract it from the other side. In this case, you subtract 132 from both sides, therefore it is D.

Answer: B

Step-by-step explanation:

We can see that the graph is being compressed, so f(x) is being transformed into f(ax), where 0<a<1.

The only option that satisfies this is y=f(x/2).

Step-by-step explanation:

The resultant polynomial which is the correct simplification and demonstration of the closure property of give expression is,

[tex]-5x^3 +4x^2- 5x[/tex]

This resultant expression is polynomial.

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).

The given expression in the problem is,

[tex](3x^3 +2x^2 - 5x) - (8x^3 - 2x^2).[/tex]

Let the resultant polynomial of the above expression is f(x). Therefore,

[tex]f(x)=(3x^3 +2x^2 - 5x) - (8x^3 - 2x^2).[/tex]

To solve the above polynomial, open the bracket by multiplying the sign with inside values as,

[tex]3x^3 +2x^2 - 5x - 8x^3 +2x^2[/tex]

Separate the same power terms of the variables as,

[tex]f(x)=3x^3- 8x^3 +2x^2 +2x^2- 5x\\f(x)=-5x^3 +4x^2- 5x[/tex]

The volume of a cylinder is the amount of space in it

The radius of the cylinder is 3 feet

The volume of a cylinder is:

[tex]V = \pi r^2 h[/tex]

Where r represents the radius, and h represents the height

So, we have:

[tex]108\pi = \pi r^2 * 12[/tex]

Divide both sides by 12pi

[tex]9 = r^2[/tex]

Take the square roots of both sides

3 = r

Rewrite as:

Use the law of sines:

Find the missing angle:

Use the law of sines to find the length of b:

Step-by-step explanation:

First problem looks right. Although he started with 145, not 25. Savings and checking combined is the total amount of cash he had before he started working, which is why it's added to the total amount of money he has.

He saves 55 every week. because the multiplier on w, which is weeks is 55. So for every week 55 is added to the multiplication. Ex 2 weeks is 110, 3 is 165, 4 is 220 etc..

He wanted a total of 650 usd. Doesn't matter where it is the total is what matters. Doesn't matetr if hes spending,  storing or even burning the money..
So first make 55w+145=650 then solve

Minus 145 from both sides

55w = 505

About 9 weeks one day and 6 hours. This is a rough estimate since the answer is 9.18181818 weeks.
