Find the slope of the line through the given points. (1,3) and (0,−9)

Thank you so much :)

Answers

Answer:

The answer is 12

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(1,3) and (0,−9)

The slope is

[tex]m = \frac{ - 9 - 3}{0 - 1} = \frac{ - 12}{ - 1} = 12 \\ [/tex]

We have the final answer as

12

Hope this helps you

The roots of a quadratic equation are 7 and -3. Which quadratic equation has these roots?
(x + 7) (x – 3) = 0

(x - 7) (x + 3) = 0

(x – 7) (x – 3) = 0

(x + 7) (x + 3) = 0

Answers

The answer is (x - 7) (x + 3) = 0

Explanation: Put both equations equal to 0, so it looks like this: (x - 7) = 0 (x + 3) = 0
It doesn’t matter what you do first but I’ll start with (x - 7) = 0
First you remove the parenthesis
x - 7 = 0
Next you add the 7 on both sides. You do this to cancel the 7 so that the x is by itself.
x = 7
It’s the same thing for the (x + 3) = 0 but I’ll show you anyways
Remove parentheses
x + 3 = 0
Subtract the 3 from both sides that way the 3 cancels out and the x is on its own
x = -3

Find the scale factor,and find the unknown side lengths.

Evaluate (18)^2-(15)^2
Please show working.

Answers

Answer:

99

Step-by-step explanation:

You can solve it by Squaring/multiply 18 by itself and 15 by itself then subtract them both:

(18 × 18) - (15 × 15)

324 - 225

99

You could also do difference of two squares:

(x² - y²)

= (x + y) (x - y)

= (18 + 15) (18 - 15)

= (33) (3)

= 99

Answer:

99

Step-by-step explanation:

Evaluate

= (18)^2-(15)^2

= 324 - 225

= 99

Question Says:-

An equilateral triangle is a triangle with three equal sides. The perimeter of an equilateral triangle varies directly with the length of one side. What is an equation that relates the perimeter p and length of a side?

Answer:-

See, let us consider the sides as l as per question.

And, perimeter as p as per question.

We know that:-

The sum of all the boundary gives us the perimeter of the figure.

It is Equilateral Triangle, so the equation will be:-

[tex]l + l + l = p[/tex]

Now, adding it up, we get

[tex]3l = p[/tex]

So, 3l=p relates the side and perimeter.

Hope it helps :)

Find the value of x. Draw a triangle and label each interior angle before solving.
Then find the angle measures of the polygon.

Angle one: 2x°, angle two: xº, angle 3: (X + 8)°

Answers

Sum of all angles in a triangle = 180°

Which means :-

∠1 + ∠2 + ∠3 = 180°

[tex]2x + x + x + 8 = 180°[/tex]

[tex]4x + 8 = 180°[/tex]

[tex]4x = 180 - 8[/tex]

[tex]4x = 172[/tex]

[tex]x = \frac{172}{4} [/tex]

[tex]x = 43[/tex]

Angle 1 :-

= 2x

= 2 × 43

= 86°

Angle 2 :-

= x

= 43°

Angle 3 :-

= x + 8

= 43 + 8

= 51°

[tex]therefore \: , \: the \: value \: of \: x = 43°[/tex]
