I think of a number, double it, and subtract two. I get nine. using the statement above, from an equation. Use the letter "X" for the unknown number.
solve the equation as well.


5.5

Step-by-step explanation:

your number is X

doubling it=2X

2X-2=9

using like terms...

2X=9+2

2X=11

dividing through by 2

2X/2=11/2

X=5.5

The no. thought is 5.5

Step-by-step explanation: Let the no. thought be ' x '

2x - 2 = 9

2x = 9+2

2x = 11

x = 11/2 = 5.5

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

won't that be plagrisim thought?
