Step-by-step explanation:

y = 6x + 2 is a straight line, that is a linear function

It is valid for all real numbers , then

domain is all real numbers

The domain of the function y=6x+2 is all real numbers.

A relation is a function if it has only One y-value for each x-value.

The domain of a function is the set of all possible input values (also known as the independent variable).

In the function y = 6x + 2, x can be any real number.

There are no restrictions or conditions on the values that x can take.

The domain of this function is all real numbers.

Hence,  the domain of the function y=6x+2 is all real numbers.

Answer:

Both are equally distant from 0 on a number line.

Step-by-step explanation:

Both are equally distant from 0 on a number line, they are just in opposite directions.

Answer:

Both are same distance

Step-by-step explanation:

-8 is in the opposite direction of the positive 8

(1) Combining fractions is just a matter of writing each individual fraction in terms of a common denominator. The least common multiple of 6, 4, and 8 is

LCM(6, 4, 8) = 24

since 6×4 = 4×6 = 8×3 = 24. So

2/6 = (2×4)/(6×4) = 8/24

1  1/4 = 4/4 + 1/4 = 5/4 = (5×6)/(4×6) = 30/24

13  4/8 = 104/8 + 4/8 = 108/8 = (108×3)/(8×3) = 324/24

Then

2/6 + 1  1/4 + 13  4/8 = 8/24 + 30/24 + 324/24 = 362/24 = 181/12

(2) We have

LCM(12, 9) = 36

since 12×3 = 9×4 = 36. Then

121  2/12 = 1452/12 + 2/12 = 1454/12 = (1454×3)/(12×3) = 4362/36

781  6/9 = 7029/9 + 6/9 = 7035/9 = 2345/3

Answer:

NO

Step-by-step explanation:

We can see that the denominator 7, multiplied by 4 = 28

But 3 multiplied by 4 is not 8

The proper fraction would be 12/28

 NO = 10

Step-by-step explanation:

The segment addition theorem tells you ...

 MN + NO = MO

Substituting the given expressions for these lengths, we have ...

 x + 5x = 3x+6

 3x = 6 . . . . . . . . . subtract 3x

 x = 2 . . . . . . . . . . divide by 3

We can use this value to find the length NO:

 NO = 5x = 5(2) . . . . substitute for x

 NO = 10

The degree of the monomial 3x4y3 is 7

Answer:

2:1.

Step-by-step explanation:

The area of a red  curved surface = 2πr^2.

The area of the yellow flat surface = πr^2.

This is the case for all the hemispheres.

Therefore the  required  ratio =  2πr^2 :  πr^2

= 2:1.

Answer:

-36

Step-by-step explanation:

We have the equation 4 lm - nl , along with the values, m is equal to -7 and n is equal to 2.

To solve, we need to only substitute the values of each variable into the original equation :

4 |-7 - 2|

First solve the equation within the absolute value, any value that comes out of those brackets become positive :

|-7 - 2|

|-9|

4|-9|

4(-9)

Now multiply to get our answer:

4(-9)

-36

Answer:

  x +4y = -5

Step-by-step explanation:

The equation of the perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The new constant can be found by substituting the point values into the equation.

  3x +12y = 3(-5) +12(0)

  3x +12y = -15

We notice that all of the values include a factor of 3. We can divide that out to put the equation in standard form:

  x + 4y = -5

1 =b

Step-by-step explanation:

8 = b - 1 + 8b

Combine like terms

8 = 9b -1

Add 1 to each side

8+1 = 9b-1+1

9 = 9b

Divide each side by 9

9/9 = 9b/9

1 =b

Answer:

1

Step-by-step explanation:

Group like terms

8b + b = 8+ 1

simplify each sides

9b = 9

divide both sides by 9

9b÷9 = 9÷9

cancel out

answer is equal to 1

b = 1

Answer:

A number of tourists were interviewed on their choice of means of travel. Two- thirds said that they travelled by road, 1330 by air and 415 by both air and road. If 20 tourists did not travel by either air or road ; (i) represent the information on a Venn diagram ; (ii) how many tourists (1) were interviewed ; (2) travelled by air only?

Answer:

a: [tex]\$ 14[/tex] or [tex]14[/tex] dollars

b: [tex]\$0.57[/tex] or [tex]57[/tex] cents

c: [tex]\$14.57[/tex] or [tex]14[/tex] dollars and [tex]57[/tex] cents

Step-by-step explanation:

a: We have [tex]2[/tex] [tex]\$5[/tex] bills, which have a total value of [tex]2*5= \$10[/tex]. We also have [tex]4[/tex] [tex]\$1[/tex] bills, which have a total value of [tex]4*1= \$4[/tex]. Adding these up gives us  [tex]10+4= \bf \$14[/tex] or [tex]\bf 14[/tex] dollars for the total value of the bills.

b: Remember that a quarter is worth [tex]\$0.25[/tex], a nickel is worth [tex]\$0.05[/tex], and a penny is worth [tex]\$0.01[/tex]. Therefore, [tex]2[/tex] quarters are worth [tex]2*0.25=\$0.50[/tex], [tex]1[/tex] nickel is worth [tex]1*0.05=\$0.05[/tex], and [tex]2[/tex] pennies are worth [tex]2*0.01=\$0.02[/tex]. Adding these up gives us [tex]0.50+0.05+0.02=\bf \$0.57[/tex] or [tex]\bf 57[/tex] cents for the total value of the coins.

c: We know that the total value of the bills is [tex]\$ 14[/tex] (or [tex]14[/tex] dollars) from Part A and the total value of the coins is [tex]\$0.57[/tex] (or [tex]57[/tex] cents) from Part B. Therefore, we have [tex]14+0.57=\bf \$ 14.57[/tex] in total or [tex]\bf 14[/tex] dollars and [tex]\bf 57[/tex] cents.

Hope this helps!
