Find the slope of the line that passes through the points. (10,8) and (4,12) is as a simplified fraction

Answers

Answer:

- 2/3

Step-by-step explanation:

Slope m = (y2-y1) / (x2-x1)

= (12-8) / (4-10)

= 4 / (-6)

= - 2/3

The slope as a simplified fraction is : - [tex]\frac{-2}{3}[/tex]

Meaning of slope

Slope or gradient is the degree of steepness of a line.It is the ratio of the chance in the y- coordinates to the change in the x-coordinates of a line.

m( slope) = [tex]\frac{y2-y1}{x2-x1}[/tex]

Given data

x1 = 10, x2 = 4, y1 = 8, y2 = 12

Therefore the slope can be calculated as :

m = [tex]\frac{y2-y1}{x2-x1}[/tex]

m = [tex]\frac{12-8}{4-10}[/tex] = -4/6 = -2/3

In conclusion the slope of the points (10,8) and (4,12) as a simplified fraction is -2/3

If ∆TIK ≅ ∆TOK and < I = (5x + 8), < K = 92, and < O is 50. What is the measure of < I?

Answers

Answer:

<I = 50

Step-by-step explanation:

Sum of angles in ∆TOK is 180

Given

< I = (5x + 8),

< K = 92, and

< O is 50.

<T + <O+<K = 180

<T +92+50 = 180

<T + 142 = 180

<T = 180-142

<T = 38

Also <T+<I+<K = 180

38+5x+8+92 = 180

5x+138 = 180

5x = 42

x = 42/5

x = 8.4

Since <I = 5x+8

<I = 5(8.4)+8

<I = 42 + 8

<I = 50

3x+ 2y= 14 4x- 2y= 16 Elimination.

Answers

If you set the problem like you are going to add it, it will look like this:

3x+2y=14
+4x-2y=16
——————

2y+(-2y) will cancel out leaving you with:

7x=30

Divide by seven to get x by itself, you will get:

x=5

Now plug that in to 4x-2y=16

4(5)-2y=16

20-2y=16

Minus 20 on both sides

-2y=16

Divide by -2 to get y by itself

y=8

Thus,

x=5 and y=8

How do you do
3x-5y=-2
x+3y=4
Please show work

Answers

3x-5y=-2
-3(x+3y=4)
You multiply the whole equation by three so you can cancel out the three x
3x-5y=-2
-3x-9y=-12
Now you can cancel out the 3x
-5y=-2
-9y=-12
Now add them together
-14y=-14
So y=1

Answers

Answer:

-1350 is the answer.

Step-by-step explanation:

The value of multiplication of 25 and -54 will be -1350/1.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The expression as;

25 × -54

Now. Solve the expression as;

25 × -54 = - 1350

It can be written as a fraction;

- 1350 = -13500/10

After simplified we get;

- 1350 = -13500/10

A circle has a diameter of 10 cm a square has a side length of 6 cm use Pythagoras Theorem to show that the square will fit inside the circle without touching the edge of the circle

Answers

Given:

Diameter of circle = 10 cm

Side length of square = 6 cm.

To show:

That the square will fit inside the circle without touching the edge of the circle.

Solution:

A square will fit inside the circle without touching the edge of the circle if the diagonal of the square is less than the diameter of the circle.

We have,

Side length of square = 6 cm.

Using Pythagoras theorem, the diagonal of the square is

[tex]Hypotenuse^2=perpendicular^2+base^2[/tex]

[tex]d^2=a^2+a^2[/tex]

[tex]d^2=2a^2[/tex]

Taking square root on both sides.

[tex]d=\sqrt{2a^2}[/tex]

[tex]d=a\sqrt{2}[/tex]

Putting a=6, we get

[tex]d=6\sqrt{2}[/tex]

[tex]d=6(1.414)[/tex]

[tex]d=8.484<10[/tex]

Since, the diagonal of the square is less than the diameter of the circle, therefore the square will fit inside the circle without touching the edge of the circle.

Hence proved.
