Step 1: Draw line x =1.Why is x=1 like this, just plug in any values of y, for example y=14, x=1, you have point (1,14), and when y=-14,x=1, you have point (1,-14). Connect 2 points for a straight line.This line is x=1.

Coordinates for reflection of K is (6,-5),
reflection of H is (14,-5),
reflection of I is (14,-9),
reflection of J is (6,-9).

Step 1: Draw a line from K to origin. Measure this line.

Mr. T

Step 2: Extend the line of same length, this is K after 180 degrees counter closewise.

Step 3: Do the same steps for J, you should get (4,9)

Mr. T

Step 4: Repeat for point I, you should get (12,9).

Lastly, repeat for H you should get (12,5).

What it means 180 degrees counterclockwise about origin is place your protractor at origin

1 year ago

Mr. T

With 0 degree along the line joining from origin to the point

Mr. T

Then draw another point at 180 degrees first, then measure the same length, that is the point after 180 degrees counterclockwise rotation about the origin.

Mr. T

This is how the protractor is place for point K.

Factorize using a common factor

Mr. T

we can first combine the terms 10x and -14 to get 10x - 14 = 2(5x - 7). Then, we can substitute this expression into F:
F = (5x-7)(2x+1) + 2(5x - 7)

1 year ago

Mr. T

Now, we can see that (5x - 7) is a common factor of the two terms, so we can factor it out:
F = (5x - 7)(2x + 1 + 2)

Mr. T

Simplifying the expression inside the parentheses, we get:
F = (5x - 7)(2x + 3)
Therefore, the fully factorized form of the expression F is:
F = (5x - 7)(2x + 3)
