Answer:

-2/3

Step-by-step explanation:

Well you would use slope-intercept formula: $\frac{y_2-y_1}{x_2-x_1}$ . Then you need to plug in your numbers so it would look like $\frac{5-3}{-2-1}$ . then it would look like $\frac{2}{-3}$ and that would be your m. The next step would be to

How to add x+6+x please answer

cricket20 [7]

Answer:

2(x+3)

Step-by-step explanation:

when adding, take the constant aside and group the similar variables together. In this case, the constant was 6 and the variable was x.

x+ x+ 6, can also be written as (2 times x) + 6.

= 2x + 6, which can also be written as 2(x+3)

Hope this helps.

PLS HELP Find the value of x.

Brilliant_brown [7]

Answer:

Step-by-step explanation:

In algebra, it is easy to find the third value when two values are given. Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side.

Calculate the slope of the line for Graph B.

Alex

Answer:

-1

Step-by-step explanation:

rise = -2

run = 2

Slope = rise / run

= -2/2 = -1

Since also the angle made by the line and x axis in anti clockwise direction is > 90° the slope will be-ve .

I need help with this pls

antoniya [11.8K]

I'll explain it simply for you

1st question
Of course you know phythagoras theorm
You even wrote it up there
It states that the sum of the square of the two sides of an equilateral triangle is equal to the square of the hypotenuse
${a}^{2} + {b}^{2} = {c}^{2}$
Where C is the hypotenuse
*NOTE* :
HYPOTENUSE is the greatest side in a triangle!!
And that's where your mistake is!
So you should take the greatest side as C
So in Q3. 7, 24 and 26 are the given numbers
You'll make the smaller two numbers a and b and the greatest number C
Using the Formula you'll solve the left side first which is
${a}^{2} + {b}^{2}$
Then the right side which is
${c}^{2}$

And if both are equal then it is a right triangle otherwise it isn't!
Let
a=7
b=24
c=26

a^2 + b^2
7^2 + 24^2
49 + 576 = 625
GREAT, Now the right side

26^2 = 676
Since they aren't equal it isn't a right angled triangle...

Then let
a=7.5
b=10
c=12.5

7.5^2 + 10^2
= 56.25 + 100
= 156.25

12.5^2 = 156.25

They are EQUAL
Therefore it is a right triangle too

Hopefully I helped

Is line AB tangent to the circle ?

galben [10]

Answer:

Yes

Step-by-step explanation:

A tangent has one point touching the circle and is always perpendicular to the radius drawn in as well. Therefore line AB is tangent to the circle and creates a right triangle.
