Answer:

Step-by-step explanation:
Angular speed is given by
, where
is angle change in radians and
is elapsed time.
Since the baseball makes one fourth (one quarter) of a rotation in 1.35 seconds, it will take the baseball
seconds to complete on rotation.
One rotation is 360 degrees or
radians. Therefore, the angular speed of the baseball is:

B
Answer:
x=12
Step-by-step explanation:
<span>2y = 4x + 8 ------> y = 2x + 4
4y = 4x + 20 ------> y = x+5
2x+4 =x+5
x = 1
y=x+5=1+5=6
Check:
</span>2*6 = 4*1 + 8 , 12 =12
4*6 = 4*1 + 20, 24 =24<span>
x=1,y=6
(1,6)
