Answer:

i. 10 units (Carol's house is 10 units on the right from Ann's house)

ii. -10 units (Carol's house is 10 units on the left to Ann's house)

Step-by-step explanation:

A number line is a system that can be used to express the location of directed number on a straight line. It has an origin which is taken to be zero (0).

In the given question, Ann's house is located at 0 of the number line. Let 1 block be represented by 1 unit on the number line.

Thus, Ben lives 8 blocks from Ann implies that Ben's house is at 8 units from Ann's house.

Given that Carol's house is 2 blocks from Ben implies that Carol's house is 2 units from Ben.

So that,

The possible locations of Carol's house depends on its position with respect to Ann's house.

i. Carol's house = 8 + 2

                          = 10 units

This implies that Carol's house is 10 units on the right from Ann's house.

ii. Carol's house = - 8 - 2

                           = -10 units

This implies that Carol's house is 10 units on the left to Ann's house.

Answer:

A. 1,112

Step-by-step explanation:

The manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.

Option A is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example: so

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let's start by finding the profit per chair:

So,

Profit per chair = Selling price - Production cost

= $55.75 - $16.91

= $38.84

Next, we need to determine how many chairs the manufacturer needs to sell to make a profit of $24,850:

Profit = Profit per chair x Number of chairs sold - Overhead costs

$24,850 = $38.84x - $18,340

$43,190 = $38.84x

x = 1,112.49

Rounding to the nearest whole number, the manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.

Therefore,

The manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.

Answer:85

Step-by-step explanation: In this problem you are trying to find the missing angle of a line. In a line all angles have to add up to 180 so what you wanna do first is add 55 and 40 which gives you 95. Next, you wanna subtract 95 from 180 which will give you 85. Now you know the missing angle.

f(x)=2x+5

Step-by-step explanation:

If you think about it, 5 is the y intercept, meaning the money he earn that day. While Sunday, he earned more which is the Slope of 2x because its 2 times the number. And you add them together, and there you go.

X × X - X × X × X × X × X + 17= X × X × X + 2

Answer:

X-Intercept: [tex]x=-\frac{5}{2}y[/tex]

Y-Intercept: [tex]y=-\frac{2}{5}x[/tex]

Step-by-step explanation:

X-Intercept-

2x+5y=0     - Move the variable to the right-hand side and change its sign

2x=-5y     - Divide both side of the equation by 2

x=-5/27     - Write the solution x in parametric form

x=-5/2y, y∈R

Y-Intercept-

2x+5y=0    - Move the variable to the right hand side and change its sign

5y=-2x     Divide both sides of the equation by 5

y=-2/5x     Write the solution y in parametric form

y=-2/5x, x∈R

Answer: D: Y=(x-1)(x-1)

Step-by-step explanation:

The function described by the graph is [tex](x-1)^2[/tex].

Therefore, the correct answer is Option D. y = ( x - 1 ) ( x - 1 )

Given data:

The function is represented as f(x) = y

Now, the value of f(x) is plotted below:

To plot the graph, start by determining some key points and then connecting them.

When x = 0:

f(0) = 1

So, the point is (0, 1).

When x = 1:

f(1) = 0

So, the point is (1, 0).

When x = 2:

f(2) = 1

So, the point is (2, 1).

The graph of [tex]f(x) = (x - 1)^2[/tex]  is a parabola that opens upwards. The vertex of the parabola is at the point (1, 0), which corresponds to the minimum value of the function.

As x moves further away from 1 in either direction, the function increases.

Hence, the parabolic function is [tex]f(x) = (x - 1)^2[/tex].

Answer:

The range of the graph is {y: y ∈ R, -6 ≤ y ≤ 8}

Step-by-step explanation:

The domain is the set of values of the input (x)

The range is the set of values of the output (y)

In the given figure

∵ x is the input

∴ The set of the values of x is the domain

∵ Y is the output

∴ The set of the values of y is the range

∵ The smallest value of y is -6

∵ The greatest value of y is 8

→ That means values of y of the graph are from -6 to 8

∴ -6 ≤ y ≤ 8

∴ The range = {y : y ∈ R, -6 ≤ y ≤ 8}

∴ The range of the graph is {y: y ∈ R, -6 ≤ y ≤ 8}

The answer to the question provided is

[tex] \frac{1}{4} [/tex]

Answer:

x = 2

Step-by-step explanation:

Both equations are equal to y, so they're also equal to each other.  We then set them equal to each other:

x^2 - 2x + 1  =  x^2 + 2x - 7

We now do algebra to isolate x.  Subtract 1 from both sides.

x^2 - 2x  =  x^2 + 2x - 8

Subtract 2x from both sides.

x^2 - 4x  =  x^2 - 8

Subtract x^2 from both sides.

-4x = -8

Divide both sides by -4.

x = 2

Answer:

  7. c(n) = 10 +2(n -1)

  8. c(20) = 48

Step-by-step explanation:

7. Your arithmetic sequence has first term a1=10 and constant difference d=2. The explicit formula for terms of an arithmetic sequence is ...

  an = a1 +d(n -1)

If we use c(n) as the function name for the function giving the number of chairs in row n, then we can fill in the numbers we know to get ...

  c(n) = 10 + 2(n -1)

__

8. Evaluating the function when n=20, we find ...

  c(20) = 10 +2(10-1) = 10 +2·19 = 10 +38

  c(20) = 48

There are 48 chairs in row 20.

Answer:

The correct option is B.

Step-by-step explanation:

Consider the provided information.

The dimensions of bricks are in inches so convert foot into inches.

1 foot = 12 in

4 feet = 48 in

8 feet = 96 in

To calculate the number of bricks that fit into space we divide the space's volume by the volume of 1 brick.

[tex]\text{Number of bricks in space}=\dfrac{12\times 48 \times96}{3\times 4 \times8}[/tex]

[tex]\text{Number of bricks in space}=576[/tex]

Hence, 576 bricks can be fit into a space.

Therefore the correct option is B.

Answer:

x = 2/5 or 0.4

Step-by-step explanation:

3x - 6 = 4(2 - 3x) - 8x

distribute

3x - 6 = 4*2 - 4*3x - 8

3x - 6 = 8 - 12x - 8

combine like terms

3x - 6 = -12x

add 12x to both sides of the equation

3x - 6 + 12x = -12x + 12x

3x - 6 + 12x = 0

15x - 6 = 0

add 6 to both sides of the equation

15x - 6 + 6 = 0 + 6

15x = 6

divide both sides of the equation by 15

15x/15 = 6/15

x = 6/15

x = 2/5

x = 0.4
