135

Step-by-step explanation:

360/8=45

45x3=135

To graph the equations (sorry i dont have a camera), use the up/down line and on the 6 put a dot, then move one space to the right, and four squares down to place your next dot. This is for y = -4x+6. To graph y = 4x - 2, go back to the up/down line, to the -2 part, and put a dot. then go to the right once, and up four times to place your next dot. when the lines connect, you should be able to find your point, at (1, 2)

Answer:

-2x + 1

Step-by-step explanation:

1: -3x^2 + 5x + 2 - 1 - 7x + 3x^2

2: (-3x^2 + 3x^2) + (5x - 7x) + (2 - 1)

3: 0 - 2x + 1

4: -2x + 1

Step 1: Given equation

Step 2: Group the terms with similar exponents together

Step 3: Add the terms together

Step 4: Simplify completely

Cos(x)=Adj/ Hyp

Hyp*Cos(x) = Adj

30* Cos(45) = Adj

30* [tex]\sqrt{2}/2[/tex] = Adj

15*[tex]\sqrt{2}[/tex] = Adj  ( both legs are the same )

Answer:

x = 2 and y = 1

Step-by-step explanation:

Given equations are :

2x-y=3 ...(1)

3x+y=7 ...(2)

Add equation (1) and (2) as follows :

2x-y + 3x+y = 3 + 7

2x + 3x = 10

5x = 10

x = 2

Put the value of x in equation (1)

2(2)-y=3

4-y = 3

y = 4-3

y = 1

Hence, the solution of the given equations are (2,1).

Answer:

[tex]\displaystyle \frac{9}{\sqrt{7}-2}=3\sqrt{7}+6[/tex]

Step-by-step explanation:

Rationalizing the Denominator

Rationalizing the denominator means to get rid of any radicals in the denominator.

We use the conjugate of the denominator to rationalize. The conjugate of a binomial is obtained by changing the sign that is between the two terms while keeping the same order of the terms. For example, the conjugate of

[tex]\sqrt{7}-2[/tex] is [tex]\sqrt{7}+2[/tex].

We need to use the algebraic identity:

[tex](a-b)(a+b)=a^2-b^2[/tex]

Let's rationalize

[tex]\displaystyle \frac{9}{\sqrt{7}-2}[/tex]

Multiply numerator and denominator by the conjugate of the denominator:

[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9}{\sqrt{7}-2}\cdot\frac{\sqrt{7}+2}{\sqrt{7}+2}[/tex]

Operate in the numerator and apply the identity in the denominator

[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9(\sqrt{7}+2)}{(\sqrt{7}-2)(\sqrt{7}+2)}[/tex]

[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9\sqrt{7}+18}{(\sqrt{7})^2-2^2}[/tex]

[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9\sqrt{7}+18}{7-4}=\frac{9\sqrt{7}+18}{3}[/tex]

Dividing:

[tex]\boxed{\displaystyle \frac{9}{\sqrt{7}-2}=3\sqrt{7}+6}[/tex]

Answer:

40

Step-by-step explanation:

The volume of a cylinder is = to [tex]\pi[/tex][tex]r^{2}[/tex]h, so plug in the values and you get that each crayon has a volume of about 0.15 inches. 6/0.15 = 40. :)

Answer:

300,000.

Step-by-step explanation:

6x10^-3 /  2x10^-8

= 3 x (10^(-3- (-8))

= 3 x 10^5

= 300,000

Answer:

-1/7

Step-by-step explanation:

Start at -7 then go up to -6 then just go right 1

Answer:

12

Step-by-step explanation:

y = 6; z = 6

3y - z = 3(6) - 6 = 18 - 6 = 12

Answer:

12

Step-by-step explanation:

3y-z is asking 3 x 6 - 6, which equals 12

(3 x 6 = 18 and 18 - 6 = 12)

Answer:

£168

Step-by-step explanation:

Amount to be shared = 560

Roshana's share = x

Nima's share = 3x

Kate's share = 2 * 3x = 6x

X + 3x + 6x = 560

10x = 560

x = 560 / 10

x = 56

Nima's share = 3x

Nima's share = 3* 56 = £168

Answer:

A: $6

B: $2.01

C: $0

D: $4.50 or $7.50

E: 0 ≤ x ≥ 10

F: The more expensive you make the toy then that will mean that less people will want to buy it for its high price.

Step-by-step explanation:

Answer:

Domain: Al real values

Range: All real numbers

Step-by-step explanation:

Let f(x)=e^x and g(x)=x+6. What is the domain and range of (GoF) (x)?

Given the functions'

f(x)=e^x and g(x)=x+6.

gof(x) = g(f(x))

g(f(x)) = g(e^x)

Substitute x with e^x in g(x) as shown:

g(f(x)) = e^x + 6

The domain s the input value of x for which the function exists. Accordinf to the expression, x exists on all real values. Since x exists on all real values, hence the output f(x) also exists on all real values

Answer:You have 4 quarters and 45 pennines  

Step-by-step explanation:

Answer:

m = 35, n = 110

Step-by-step explanation:

Opposite angles are congruent , then

2m = 70 ( divide both sides by 2 )

m = 35

Consecutive angles are supplementary, that is sum to 180° , so

70 + n = 180 ( subtract 70 from both sides )

n = 110
