Answer:
Equivalent expressions are expressions which are equal. This means they simplify to the same expression. Simplify the two expressions -1.3x - (-8.9x) = 7.6x and -1.3 + (-8.9X) = -10.2x.
Then simplify each option to determine if it is equal -1.3x - (-8.9x), -1.3 + (-8.9X) or neither:
−1.3x−8.9x = -10.2x. This is equivalent to -1.3 + (-8.9X) .
8.9x+(−1.3x) = 7.6x This is equivalent to -1.3x - (-8.9x) .
−8.9x+(−1.3x) = -10.2x This is equivalent to -1.3 + (-8.9X) .
8.9x−(−1.3x) = 10.2x Neither
−1.3x+8.9x = 7.6x This is equivalent to -1.3x - (-8.9x) .
−8.9x+1.3x = -7.6x Neither
Step-by-step explanation:
Yes it is a function because non of the X values are repeating

Answer:
1,890 minuts
Step-by-step explanation:
3 weeks = 7 days x 3 = 21 days
He rides his bike for "45 minutes to get to school and 45 minutes to get home" which is 90 minutes per day.
Therefore, in total, he rode for 21 days x 90 minutes per day = 1,890 minutes
Eccentricity = foci / half the length of the major axis
= 3.5 / 14 = 1/4
