Answer:

y = 3x - 9

Step-by-step explanation:

Let's start by finding the slope of the line:

The formula for slope is [tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex].

Plug in the numbers and solve:

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

[tex]m = \frac{-3 - (-6)}{2 - 1}[/tex]

[tex]m = \frac{3}{1}[/tex]

[tex]m = 3[/tex]

The slope of the line is 3.

The slope intercept form of a line is y = mx + b, where m is the slope and b is the y coordinate of the y-intercept.

Plugging in the number we got for the slope, the equation becomes:

y = 3x + b

Let's solve for b by plugging in an ordered pair for y and x:

y = 3x + b

-3 = 3(2) + b

-3 = 6 + b

b = -9

The y-coordinate of the line is (0, -9).

Now, plugging in the number into our equation, we get:

y = 3x + (-9)

y = 3x - 9

And that's the equation of the line!

Answer:

280.6 [tex]m^2[/tex]

Step-by-step explanation:

find the length of each side:

you're only given h = 9 m

the formula for h is  [tex]h=\frac{\sqrt{3} }{2} *a[/tex], where a is a side length of the hexagon

plug h in:

[tex]9=\frac{\sqrt{3}}{2}*a\\\\a=9*\frac{2}{\sqrt{3}}\\\\[/tex]

a ≈ 10.392 m

now find the area of a triangle:

1/2 (10.392)(9) = 46.764 [tex]m^2[/tex]

multiply that by 6 and you get 280.584 ≈ 280.6 [tex]m^2[/tex]

you can also use the regular hexagon area formula instead of finding the individual area and multiplying by 6: [tex]\frac{3\sqrt{3} }{2} *a^2[/tex]

Answer:

Yes

Step-by-step explanation:

Yes. It could be a square if all sides are also the same measure.

A parallelogram will be a square when all four sides are of equal in length and all four angles are same.

Answer:

a)ABC ≅ A'B'C' (SSS) b) Enlargement c) Scale factor = 4

Step-by-step explanation:

a) ABC ≅ A'B'C' (SSS)

b) The figure is going through an enlargement, this is evident as the figures have a scale factor of 4. If we were to put them into a fraction like this -

6/24=12/48=15/60

The figures are getting bigger, so they are going through an enlargement.

c) To find the scale factor of like done above, we could put them into a ratio.

6/24=12/48=15/60

Which would result in the scale factor of 4.

Answer:

1/25

Step-by-step explanation:

Probability of an event = number of required outcomes / number Total possible outcomes

Total number of possible outcomes = (0, 1, 2, 3, 4) = 5

Required outcome = (2) = 1

P(2) = 1 /5

.

Second spin

P(2) = 1 /5

Therefore, the probability of ;

P(2, then 2) = first spin * second spin = 1/5 * 1/5 = 1/25

Answer:

3.15 cents

Step-by-step explanation:

So, lets go over all the information we know.

First off, we know that the cost of the item is 70 dollars.

Secondly, we know that the fee is 4.5% of 70 dollars.

Now, what is 4.5%?

Well, we know that 100% is qual to 1.

So lets divide 4.5 by 100, which is just moving the decimal point back by 2:

0.045

Now, the last thing to do is multiply 0.045 by 70.

0.045x70

=

3.15

So now we know the fee for a 70 dollar item is 3.15 dollars!

Hope this helps ;)
