9/2 is the slope. Slope defines how steep is the straight line.

Slope =  change in y ÷ change in x

In this model, 9 refers to the vertical distance between two points

and 2 refers to  the horizontal distance between two points.

9/2 is a positive slope. It indicates that if 'x' increases, y also increase.

Step-by-step explanation:

i stands for imaginary number, in which i² = -1

6i² = 6 * -1 = -6

-6 - 7i - 3

Combine like terms:

-6 - 3 = -9

-7i - 9

What is the area of the polygon in the picture.

Answers

Answer:

I got 11

Step-by-step explanation:

Answer:

12.25 cm^2

Step-by-step explanation:

Draw a segment from the bottom of the 1.5-cm vertical side to the bottom side of the entire polygon.

Now you have two rectangles.

The left rectangle has dimensions 3.5 cm by 1.5 cm.

The right rectangle has length 5 cm - 1.5 cm = 3.5 cm and width 3.5 cm - 1.5 cm = 2 cm.

The total area is the sum of the areas of the two rectangles.

area of rectangle = length * width

total area = 3.5 cm * 1.5 cm + 3.5 cm * 2 cm

total area = 5.25 cm^2 + 7 cm^2

total area = 12.25 cm^2

What is the value of x in this equation​

Answers

Answer:

x = 5

Step-by-step explanation:

6x - 3 = 3x + 12

-3x       -3x

_____________

3x - 3 = 12

    +3    +3

_____________

3x = 15

15 divided by 3 = 5

x = 5

You can double check this by replacing x with (5)

If it is right both sides should equal the same

6(5) - 3 = 3(5) + 12

30 - 3 = 15 + 12

27 = 27

This would prove that x = 5

the value of x=5 I think

Jerome found the lengths of each side of triangle QRS as shown, but did not simplify his answers. Simplify the lengths of each side to answer the question Which statement about triangle QRS is true?

Answers

Answer:

[tex]QR = 6.0033[/tex]

[tex]QS = 8.22[/tex]

[tex]RS = 6.0033[/tex]

QRS is isosceles

Step-by-step explanation:

Given

See attachment for complete question

From the attachment, we have the following parameters[tex]QR = \sqrt{(-3-0)^2+(-5.2-0)^2}[/tex]

[tex]QR = \sqrt{9+27.04}[/tex]

[tex]QS = \sqrt{(-3-5)^2+(-5.2-(-3.322))^2}[/tex]

[tex]QS = \sqrt{64+3.53} = \sqrt{67.53[/tex]

[tex]RS = \sqrt{(0-5)^2 + (0 - (-3.322))^2}[/tex]

[tex]RS = \sqrt{(25 + 11.04}[/tex]

Solving further, we have:

[tex]QR = \sqrt{9+27.04}[/tex]

[tex]QR = \sqrt{36.04}[/tex]

[tex]QR = 6.0033[/tex]

[tex]QS = \sqrt{64+3.53} = \sqrt{67.53}[/tex]

[tex]QS = 8.22[/tex]

[tex]RS = \sqrt{25 + 11.04}[/tex]

[tex]RS = \sqrt{36.04}[/tex]

[tex]RS = 6.0033[/tex]

From the calculations;

[tex]RS = QR = 6.0033[/tex]

This means that: QRS is isosceles

If a= 2ft and c= 11ft. Find the missing side of the right triangle

Answers

Answer:

[tex]\sqrt{117}[/tex] or [tex]3\sqrt{13}[/tex]

Step-by-step explanation:

The formula for finding the any side of the triangle is

[tex]a^{2}+b^{2} =c^{2}[/tex]

We know that a=2 and c=11, so we can go ahead and plug those into the formula.

[tex]2^{2}+b^{2} =11^{2}[/tex]

[tex]4+b^{2} =121[/tex]

To find side b, we have to make it alone on one side. Subtract 4 on both side.

[tex]b^{2} =117[/tex]

Now square root both sides, and that leaves us with:

[tex]b=\sqrt{117}[/tex] or [tex]3\sqrt{13}[/tex]

Answers

Answer:

1 hour 37 minutes

Step-by-step explanation:

Given that :

Time Amelia started puzzle = 12 : 56

Time Amelia solved puzzle = 2 : 33

The time it took Amelia to solve puzzle :

Time Amelia solved puzzle - Time Amelia started puzzle

2 : 33 - 12 :56

12 :56 to 1 :56 = 1hr

1:56 to 2:33 = 37 minutes

Total time spent on puzzle = 1 hour + 37 minutes = 1 hour 37 minutes
