Answer:
Step-by-step explanation:
What they are asking for here is where the y-values are negative in interval format. Intervals are x things only, no y's allowed. So the interval of (-infinity, -3) indicates an x value of negative infinity to an x value of -3. The y's are negative from an x value of negative infinity to an x-value of -3, then again from an x value of almost -1 to an x value of almost positive 1. So your choice is the last one listed there.
Answer:
a straight line i think is always 180 so i think the answer is A. 81
Step-by-step explanation:
1/4 = .25 of a mile
.25 of a mile * 4 laps = 1.0 mile
1 mile * 3 = 3 miles so 4 laps (1 mile) * 3 = 12 laps.
X is the smaller number. 3x + 15 is the larger number. So x + 3x + 15 = 63. 4x + 15 = 63.
4x = 48. x = 12. (Smaller number) The larger 36 + 15 or 51.
