of the line AB.

Answer:

1) 12.8cm

2) 3.125km

Step-by-step explanation:

1) 8cm = 5km

1km= 8/5

1km = 1.6cm

8km = 8*1.6

8km = 12.8cm

2) 8cm = 5km

1cm = 5/8

5cm = (5*5)/8

5cm= 25/8

5cm= 3.125km

Answer:

1) 12.8cm

2) 3.125km

The area of the rectangle is [tex]A=12b^6+6b^3-18b^2[/tex]

Step-by-step explanation:

Area of a rectangle

A rectangle of height H and width W has an area of:

[tex]A=H*W[/tex]

The rectangle shown in the figure has a height of:

[tex]H=3b^2[/tex]

And a width of

[tex]W=4b^4+2b-6[/tex]

The area is

[tex]A=(3b^2)(4b^4+2b-6)[/tex]

Operating:

[tex]A=(3b^2)*4b^4+(3b^2)*2b-(3b^2)6[/tex]

[tex]A=12b^6+6b^3-18b^2[/tex]

The area of the rectangle is [tex]A=12b^6+6b^3-18b^2[/tex]

Answer:

1. 800,000 cm

2. 0.00005 km

Step-by-step explanation:

1. 1 km = 100,000 cm

8 km = 800,000 cm

2. 1 cm = 1/100,000 km

5cm = 0.00005 km

-2 < x/3 + 1 < 5

Subtract 1 from each side:

-3 < x/3 < 4

Multiply each side by 3:

-3 • 3 < x/3 • 3 < 4 • 3

-9 < x < 12

Using a system of equations, it is found that Kayla will pay $54.25 for 5 adult tickets and 4 children tickets.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

Amy bought 2 adult tickets and 4 children tickets for $35.50, hence:

2x + 4y = 35.50

x + 2y = 17.75

x = 17.75 - 2y

Jane bought 3 adult tickets and 3 children tickets for $36.0, hence:

3x + 3y = 36

x + y = 12

From the first equation:

17.75 - 2y + y = 12

y = 5.75.

x = 17.75 - 2 x 5.75 = 6.25.

Hence the total paid for Kayla is given by:

T = 5 x 6.25 + 4 x 5.75 = $54.25.

Step-by-step explanation:

Since you are given [tex]g(x)[/tex] and what x is equal to (in this case, -3), all you have to do is plug the x back into the original equation.

Answer:

30

Step-by-step explanation:

y = kx

k= y/x

k= 45/5

k= 9

Therefore the value of x can be calculated as follows

k= y/x

x= y/k

x= 270/9

x= 30

Step-by-step explanation:

Let the 1st paycheck be x (integer).

Mrs. Rodger got a weekly raise of ₫ 145.

So after completing the 1st week she will get ₫ (x+145).

Similarly after completing the 2nd week she will get ₫ (x + 145) + ₫ 145.

=[tex] ₫ (x + 145 + 145)[/tex]

= [tex]₫ (x + 290)[/tex]

So in this way end of every week her salary will increase by ₫ 145.

Step-by-step explanation:

The range of the original is the domain of an inverse function, and the domain of an inverse function is the range of an original. Since the original equation/function f(x) = x^2 is a parabola with vertex at (0, 0) and opening downward.

Answer:

No.

Step-by-step explanation:

Let's substitute the given coordinate pair into each inequality:

[tex]y > 2x+6\\-4 > 2(-5)+6\\-4 > -10+6\\-4 > -4\rightarrow\text{Not true!}[/tex]

Since this coordinate pair does not satisfy the inequality (note the coordinate pair must satisfy BOTH inequalities), therefore (-5, -4) is not a solution to this system of inequalities.

[tex]\displaystyle Inconsistency\:[No\:Solution][/tex]

Step-by-step explanation:

We need to isolate one pair of variables so they are set to zero. Now, in this case, we need to split one of the equations in negative half, so we will select the second equation:

[tex]\displaystyle \left \{ {{3x - 2y = 8} \atop {6x - 4y = 12}} \right. \\ \\ \\ \left \{ {{3x - 2y = 8} \atop {-\frac{1}{2}[6x - 4y = 12]}} \right. \\ \\ \left \{ {{3x - 2y = 8} \atop {-3x + 2y = -6}} \right. \\ \\ \\ \boxed{0 \ne 2}[/tex]

The fact that we have a result like this proves that we cannot obtain a solution from this system, which means that on a graph, these equations are considered parallel [no intersection, so no solution].

Answer:

18

Step-by-step explanation:

3x + 28 = 46

Subtract 28 from each side

3x + 28 = 46

3x+28-28 = 46-28

3x=18

Divide each side by 3

3x/3 = 18/3

x = 6

Find 2x+6

2(6)+6

12+6

18

Hey there!

3x + 28 = 46

SUBTRACT 28 to BOTH SIDES

3x + 28 - 28 = 46 - 28

CANCEL out d 28 - 28 because it give you 0

KEEPs 46 - 28 because it help solve for the x-value.

NEW EQUATION: 3x = 46 - 28

SIMPLIFY IT!

3x = 18

DIVIDE 3 to BOTH SIDES

3x/3 = 18/3

CANCEL out: 3/3 because it give you 1

KEEP: 18/3 because it give you the x-value.

NEW EQUATION: x = 18/3

SIMPLIFY IT!

x = 6

Now that we have your x-value we can substitute it into the equation of: 2x + 6

SIMPLIFYING:

2x + 6

= 2(6) + 6

= 12 + 6

= 18

Thus, your answer is: 18
