Answer:

Step-by-step explanation:

Slope of the line can be found using the two points, (2, 2) and (6, 10):

[tex] Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Let,

[tex] (2, 2) = (x_1, y_1) [/tex]

[tex] (6, 10) = (x_2, y_2) [/tex]

[tex] slope (m) = \frac{10 - 2}{6 - 2} [/tex]

[tex] Slope (m) = \frac{8}{4} = 2 [/tex]

Step-by-step explanation:

1/3 ( 2.55+.75) +3* 8.1

Using pemdas, parentheses first

1/3 ( 3.3) +3* 8.1

Then multiply

1.1 + 24.3

Then add

Answer:

k = am + 3mx

Group by taking common factor m

k = m(a + 3x)

Divide both sides by (a +3x)

k / (a+3x) = m

Then, m = k / (a+3x). This is the answer

Answer:

The three consecutive POSITIVE ODD integers are: 3, 5 and 7

Step-by-step explanation:

If x is an integer, then there consecutive positive odd integers are:

x , x + 2, x + 4 are three consecutive integers.

Where

First integer, a = x

Second integer, b = x + 2

Third integer, c = x + 4

We are told to:

Find three consecutive POSITIVE ODD integers such that when you multiply the first and third the result is nine less than six times the second integer.

Hence, this is represented as:

a × c = 6(b) - 9

Where

a = x

b = x + 2

c = x + 4

x (x + 4 ) = 6(x + 2) - 9

x ² + 4x = 6x + 12 - 9

x² +4x - 6x - 12 + 9= 0

x² - 2x - 3 = 0

Factorising

x² +x - 3x - 3 = 0

x (x + 1) -3(x + 1) = 0

(x - 3) (x + 1) = 0

x - 3 = 0

x = 3

x + 1 = 0

x = -1

Since, x cannot be negative for this question, x = 3

First integer, a = x = 3

Solving for:

Second integer, b = x + 2

b = 3 + 2 = 5

Solving for :

Third integer, c = x + 4

c = 3 + 4 = 7

Therefore, the three consecutive POSITIVE ODD integers are: 3, 5 and 7

Answer:

x=4

Step-by-step explanation:

since y=7x

x+7x=32

8x=32

x=4

Answer:

x=4

Step-by-step explanation:

x+y=32

y=7x

Since Y can be replaced by 7x, substitute into eq1.

x+y( notice y can be replaced by 7x) =32

x+7x=32 ( Y got replaced

8x=32

Divide 8 on both sides.

x=4

Answer:

The smaller dimension of the pool is 14 ft.

The larger dimension of the pool is 35 ft.

Step-by-step explanation:

We are told that:

The rectangular swimming pool is 6 ft deep. Thus, depth: h = 6 ft

One side of the pool is 2.5 times longer than the other.

Thus, length = 2.5(width)

l = 2.5w and width = w

Volume; V = lwh = (2.5w × w × 6) = 15w²

The amount of water needed to fill the swimming pool is 2940 cubic feet.

Thus;

15w² = 2940

w² = 2940/15

w² = 196

w = √196

w = 14 ft

Length: L = 2.5w = 2.5 × 14 = 35 ft

False, -14 is less that 35

Step-by-step explanation:

Answer:

x-14>35

Step-by-step explanation:

x-14>35

1. Replace "A number " with x

x minus 14 is more than 35

Minus = subtraction

x-14 is more than 35

Is more than translates to the inequality >

x-14>35

Answer:

a. 3/8

b. 11/3

Step-by-step explanation:

a. For this, we need to use a fraction to compare how many of each marble there are. 3 blue to 8 red. The ratio is 3 to 8 or 3/8

b. Now we have to compare how many all the marbles in the bag to just the blue marbles. All the marbles: 8+3=11, blue marbles: 3. So the ratio is 11 to 3 or 11/3

a) The ratio of blue marbles to red marbles: 3/8.

b) The ratio of all marbles to blue marbles: 11/3.

(a) To find the ratio of blue marbles to red marbles, divide the number of blue marbles by the number of red marbles.

Blue marbles: 3

Red marbles: 8

So, the ratio is 3/8

(b) To find the ratio of all marbles in the bag to blue marbles, divide the total number of marbles by the number of blue marbles.

Total marbles = 8 + 3

                       = 11

So, the ratio is 11/3.

Answer:

0.2

Step-by-step explanation:

Given the regression model :

y = 1.6x - 4.1

At x = 3

Predicted value = 1.6(3) - 4.1 = 0.7

If actual value at x = 3 is 0.9

The residual value at x = 3 ;

Residual value is the difference between the actual and predicted value :

Actual at x = 3 minus predicted at x = 3

Hence, Residual = 0.9 - 0.7 = 0.2

Residual is the difference between the predicted value and the actual value of the response variable

The residual at x = 3 is 0.2

The linear regression is given as:

[tex]y = 1.6x - 4.1[/tex]

The predicted value at x = 3 is calculated by substituting 3 for x in the linear regression

So, we have:

[tex]y = 1.6 \times 3 - 4.1[/tex]

[tex]y = 4.8 - 4.1[/tex]

[tex]y = 0.7[/tex]

The actual value is given as 0.9.

So, the residual is calculated using:

[tex]Residual =Actual - Predicted[/tex]

This gives

[tex]Residual =0.9 - 0.7[/tex]

[tex]Residual =0.2[/tex]

Hence, the residual at x = 3 is 0.2

Answer:

1. No

2. No

3. Yes

4. No

Step-by-step explanation:

The first one isn't  proportional because it doesn't  start at 0

The second one isn't proportional because there isn't  a pattern between  the coordinates

The 3rd one is a proportional relationship because it starts at 0 and there is an equal amount of space between each coordinate and there is evidentially a pattern.

Finally, the  4th one isn't proportional because the last coordinate doesn't correspond w/ the others

Answer:

x=5

Step-by-step explanation:

We kind of have to work backward.

First, we take 12+3 because when we move it over the equal sign, we make it the opposite.

12+3=15

Our new equation is now, 3x=15

We now take:

3x__=15

The blank represents x, which is 5.

Step-by-step explanation:

The amount exceeding 12,000,000 can be described by ...

  x - 12,000,000

Then 27.5% of that is ...

  0.275(x -12,000,000) = 0.275x -3,300,000

Adding 2,345,000 to that gives the expression ...

Step-by-step explanation:

Answer:

Length = 16 or -5 feet.

Width = 5 or -16 feet.

Step-by-step explanation:

Let the length of the concrete pad = l

Let the width of the concrete pad = w

Given the following data;

Area of concrete pad, a = 80ft²

Translating the word problem into an algebraic equation, we have;

[tex] l = 11 + w[/tex]

We know that, the area of rectangle, A = length * width

[tex] A = l*w[/tex]

Substituting the values into the equation, we have;

[tex] 80 = (11 + w)w[/tex]

Expanding the bracket, we have;

[tex] 80 = 11w + w^{2}[/tex]

[tex] w^{2} + 11w - 80 = 0[/tex]

*Solving the quadratic equation by using factorization method*

[tex] w^{2} + 16w - 5w - 80 = 0[/tex]

[tex] w(w + 16) - 5(w + 16) = 0[/tex]

[tex] (w - 5)(w + 16) = 0 [/tex]

Width, w = 5 feet or w = -16 feet.

Therefore, the width of the concrete pad is 5 feet or -16 feet.

To find its length, l;

[tex] l = 11 + w[/tex]

When w = 5 feet

[tex] l = 11 + 5[/tex]

Length, l = 16 feet

When w = - 16 feet

[tex] l = 11 + (-16)[/tex]

[tex] l = 11 - 16[/tex]

Length, l = -5 feet.

Hence, the dimensions of the concrete pad is 16 by 5 feet or -5 by -16 feet.
