Answer: x= -2

Step-by-step explanation: 1.) use PEMDAS

2.) distribute the 1 and -1 to (x+4) and (3x+6) --> 1+x+4 = -3x-6+1

3.) Put common terms on the same side (so x's together and the numbers together) so you will add 3 to the right side and add 3x to the left side

4.) that will get you 4x = -8 so then you will divide 4 to both sides to get x by itself

5.) Answer: x=-2

5.)

Answer: All numbers that are not rational are considered irrational. An irrational number can be written as a decimal, but not as a fraction. An irrational number has endless non-repeating digits to the right of the decimal point. So its Rational.

Answer:

17 is an irrational number.

Step-by-step explanation:

17 is a prime number with no factors other than itself and 1 therefore minus square root of 17 is an irrational number.

Answer:

The answer is 0

Step-by-step explanation:

It's between -1 and 1 and it's not positive only and it's not negative only

If 5 's multiplied many times then always unit digit will be 5.

If power of 2 is divide by 4 then , if remainder is zero then unit digit will be 6 and if remainder is 1 then unit digit will be 2 , if remainder is 2 then unit digit will be 4 and if remainder is 3 then unit digit will be 8.

First here we analyse when many of 2's is multiplied.

[tex]2^{1} =2\\2^{2} =4\\2^{3}=8\\2^{4} =16\\2^{5} =32\\2^{6}=64[/tex]

Here , we observed that after [tex]2^{4} =16[/tex] , unit digit will be repeat.

So, If power of 2 is divide by 4 then , if remainder is zero then unit digit will be 6 and if remainder is 1 then unit digit will be 2 , if remainder is 2 then unit digit will be 4 and if remainder is 3 then unit digit will be 8.

Now, analyse when many of 5's multiplied.

[tex]5^{1}=5 \\5^{2}=25\\5^{3}=125[/tex]

So, When  5 's multiplied many times then always unit digit will be 5.

Step-by-step explanation:

Given the distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex], distance between (-4, 5) and (4, 0) is calculated as follows:

Let [tex] (-4, 5) = (x_1, y_1) [/tex]

n=8

Step-by-step explanation:

[tex]-8=-16+n\\\\-8+16=-16+16+n\\\\8=0+n\\\\n=8[/tex]

Answer:

Step-by-step explanation:

-8=-16+n            

-8(+16)=-16(+16)+n    get "n" by itself by adding 16 to both sides.

      negative eight plus sixteen is positive eight. on the right side the sixteens cancel eachother out, so you are left with just "n".  

Therefore...,

Answer:

Step-by-step explanation:

You can  calculate the length of side a using the Cosine Rule:

a^2 = 32.6^2 + 41.4^2 - 2.32.6.42.4 cos pi/6

a^2 = 456.01

a = √456.01

a = 21.35

By the Sine Rule:

32.6 / sin B = 21.35 / sin pi/6

sin B =  (32.6 * sin pi/6) / 21.35

sin B = 0.76347

B = 0.869 radians.

C = pi - pi/6 - 0.869 = 1.749 radians.

Answer:

(7,4)

Step-by-step explanation:

The midpoint formula is:

[tex]M=(\frac{x_1+x_1}{2},\frac{y_1+y_2}{2})[/tex]

Let (5,6) be x₁ and y₁ and let's let (9,2) be x₂ and y₂. Thus, the midpoint is:

[tex]M=(\frac{5+9}{2},\frac{6+2}{2})[/tex]

Add:

[tex]M=(\frac{14}{2},\frac{8}{2})[/tex]

Divide by 2:

[tex]M=(7,4)[/tex]

So, our midpoint is (7,4).

And we're done!

Answer:

Coplanar

Step-by-step explanation:

Answer:

240 ft

Step-by-step explanation:

When she stops, her velocity is 0.  The first time that happens is at t = 3 minutes.  Her position at that time is equal to the area under the curve.

You can use area of a trapezoid, or you can split the shape into two triangles and a rectangle.  Watch your units!  Speed is given in ft/s, and time is given in minutes.

Using trapezoid area:

A = ½ (1 min + 3 min) (2 ft/s)

A = ½ (60 s + 180 s) (2 ft/s)

A = 240 ft

Answer:

7(45)=7(40)+7(5)

Step-by-step explanation:

We need to represent 7(45) using the distributive property to simplify.

We can write 45 as 40+5

So it becomes,

7(45) = 7(40+5)

Distributive property is : a(b+c)=ab+ac

a=7, b = 40 and c = 5

7(40+5)=7(40)+7(5)

So, the correct option is (4).

Answer:

0.08 pounds per pint.

Step-by-step explanation:

Given: The density of a certain material is such that it weighs 10 ounces per gallon.

We are to express this density in pounds per pint.

1 gallon ⇒ 10 ounces

1 pound = 16 ounces

How many pounds? = 10 ounces.

Cross-multiplying gives;

[tex]\frac{10 * 1}{16} = 0.625[/tex] pounds

1 gallon = 8 pints

The density in pounds per pint is;

0.625 pounds ÷ 8 pints = 0.078125 pounds per pint = 0.08 pounds per pint (answer rounded up to the nearest hundredth).

Answer:

First backpacker should receive $4 and the second one $2

Step-by-step explanation:

notice that the total amount of rice for the three is 600 g.

Then, the first one that gave 400 g contributed 400 out of 600, that is 400/600 = 2/3

The second one contributed 200 out of 600, that is 200/600 = 1/3

then the first one should receive 2/3 of the $6 = (2/3) x 6 = $4

and the second one should receive 1/3 of the %6 = (1/3) x 6 = $2

Answer:

• First attachment's graph is correct

• Second attachment, the area is approximately 8.6

Step-by-step explanation:

Remember that the area between two curves is defined as the following:

[tex]\mathrm{The\:area\:between\:curves\:is\:the\:area\:between\:curve\:f(x)\:and\:curve\:g(x)\:on\:interval\:[a,b]} :\\A=\int _a^b|f\left(x\right)-g\left(x\right)|dx[/tex]

We are given the curves y = 7cos(2x), and y = 7 - 7cos(2x) on interval [0, π/2]. Therefore, applying the area formula, we have the solve the following integral:

[tex]\int _0^{\frac{\pi }{2}}\left|7\cos \left(2x\right)-\left(7-7\cos \left(2x\right)\right)\right|dx[/tex]

From now on take a look at the attachment. It shows how to solve the integral, and it's exact value. The area is not 9.727 as you entered, it is approximately 8.6. Your graph however was accurate, but there can be no work shown for that as it's much easier to use a graphing calculator.

Answer: Associative Property of Addition

Step-by-step explanation: The problem (6 + 7) + 8 = 6 + (7 + 8)

demonstrates the associative property of addition.

Notice that the addends, or the number we're adding,

are the same on both sides of the equals sign, 6 + 7 + 8.

The associative property of addition tells us that when we're adding more

than two numbers, the grouping of addends does not change the sum.

For example here, (6 + 7) gives us 13, and 14 + 8 gives us 21.

On the right side, (7 + 8) gives us 15, and 6 + 15 gives us 21.

So the sum is the same, regardless of which way we group the addends.

Answer:

  y = 1/2x -4

Step-by-step explanation:

Subtract 1 from both sides of the equation and simplify.

  y = 1/2(x -6) -1

  y = 1/2x -3 -1

  y = 1/2x -4

Answer:

y=1/2x-4

Step-by-step explanation:

y+1=1/2(x-6)

y=1/2(x-6)-1

y=1/2x-6/2-1

y=1/2x-3-1

y=1/2x-4

Step-by-step explanation:

The order of function application in a composition can be reversed if ...

_____

In the first case, the composition gives an output equal to its input for the functions in either order.

In the second case, you cannot tell the functions apart, since they produce the same output for the same input. Hence, you can't tell if they are reordered or not.

Answer:c

Step-by-step explanation:

7x - 5 is the factor of 21x²+13x-2.Option B is correct.

An equation is a statement indicating the equality of two expressions that contain variables and/or numbers. In essence, equations are questions, and the pursuit of methodically resolving these questions has been the impetus for the development of mathematics.

It is given that, the expression is 21x²+13x-2.

We have to find the factor of the expression.

Algebraic expression factorization is the process of identifying two or more expressions whose product equals the given expression. Algebraic expression factorization is hence the multiplication procedure in reverse.

[tex]=21x^2+13x-20 \\\\ =\left(21x^2-15x\right)+\left(28x-20\right) \\\\ =3x\left(7x-5\right)+4\left(7x-5\right) \\\\ =\left(7x-5\right)\left(3x+4\right)[/tex]

The factors of the expression are (7x-5) and (3x-4).

Thu option B is correct.
