Ken’s predicted temperature for April is 7ºC. His prediction for May is 2ºC higher than April. He used the number line to solve the problem, starting at 0, moving right to 7, and then moving 2 units to the left. Explain Ken’s error

He should have moved 2 units right, not left.

Step-by-step explanation:

Left means it gets colder where as right means the temperature increases

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
