5 = 5+r-2r
what's the answer to this equation

Answers

Answer 1

Hi there!

5=5+r-2r

Combine like terms:

5=5-r

Move all the variables to the left, using the opposite operation:

r+5=5

r=5-5

r=0

r=0 is the answer

Hope it helps

A line includes the points (7, –7) and (11, –3). What is its equation in slope-intercept form?

Answers

The slope intercept form is y = mx + b so the slope is m and the slope in this case is -2.5. Now we substitute that in the equation. Well use the first set of ordered pairs for x and y. So now we have: -7 = -2.5(7) + b. When you solve for this you should get: -7 = -17.5 + b. Now you solve for the last part and you get: -7 = -17.5 + 10.5. So the Answer is: y = -2.5x + 10.5

Answers

Answer:

Slope is 1/3

Step-by-step explanation:

This is because the line is positive (moving upwards), and it moves up 1 unit and to the right 3 units. That means if you write it in the form of rise/run, where rise is the up or down movement and run is the left or right movement, 1 will be on top and 3 will be at the bottom.

Bonus: The line is y = 1/3x -5 (where 1/3 is slope and -5 is the y-intercept).

Hope this helps :)

Please explain how to get the measure of the angle because khan academy did not

Answers

To begin, remember that the sum of all angles must equal 180.

With that being said, take your two known angles into account.

1 - X = Unknown

2 - 102

3 - 48

To find x, simply add 102 and 48.

102 + 48 = 150, the sum of angle 2 & 3.

Remember that the sum of the whole figure must be 180. With that being said, subtract 180 and 150.

180 - 150 = 30

x = 30

To double check, add all the sides together.

102+48+30 = 180
