Answer:
1. x>20 2. x≤1 3.x<4 4.x>9 5.x≥-13
Answer:
Step-by-step explanation:
We will start with the angle that measures 57 degrees. This angle is supplementary to the one next to it coming off the straight line. 180 - 57 = 123.
The rule for quadrilaterals is that same side angles are supplementary, so the angle next to the 123-degree angle (to the immediate left of that angle 123) is 57. THAT 57-degree angle is supplementary to angle b, so angle b = 180 - 57 which is 123. So C is your answer.
Since they are the same, any change made to 1 will be the same in the other, resulting in infinite solutions.
I think you would divide each by 2 and get 1 over 1 which would be 1 squared over 1 (negative) cubed
Hope this helps!
