Answer is a= -5
Reason
Distribute multiply parentheses first
-3(a-8) +4a= -8(a+3)+3
-3a +24 +4a = -8a -24 +3
Now combine like terms to isolate “a”
-3a +4a +8a = -24 +3 -24
9a = -45
Now divide both sides by 9 to solve for “a”
a= -5
None, it’s greater than all of those answers
Answer:
C 1 hours 12 minutes
Step-by-step explanation:
We know distance is equal to rate times time
d= r*t
We know the distance is 30 miles and the rate is 25 miles per hour
30 = 25 *t
Divide each side by 25
30/25 = 25t/25
30/25 =t
6/5 =t
1 1/5 =t
Changing 1/5 hour to minutes. We know there is 60 minutes in 1 hours so 1/5 of an hour is 60*1/5
1/5 *60minutes = 12 minutes
1 hours 12 minutes
The amplitude does not affect the zeroes of cotangent function.
