Step-by-step explanation:
according to the drawing,
the domain = -2< x ≤ 3 => (-2 , 3]
the range = -5 ≤ y ≤ 4 => [-5, 4]
Answer:
a mixed number has a whole number along with a fraction, while an improper fraction is just a fraction with a bigger number on top
Step-by-step explanation:
An acute angle is <90 degrees
a right angle is equal to 90 degrees
an obtuse angle is >90 degrees
Any triangle has angles adding to 180 degrees
therefore three acute angles, eg. 60, 60 and 60 degrees can make up a triangle
2 acute angles and a right angle, say 45 and 45 degrees and 90 degrees make a triangle
any obtuse angle + a right angle will be larger than 180 degrees, so no triangle can exist. another acute angle will make the number of degrees even larger
any 2 obtuse angles will make a number larger than 180 degrees, so with an acute angle is impossible
2 acute and an obtuse angle is possible, say 40, 40 and 100 degrees
