The first term is 7. This is because the sequence has a pattern of increasing by 7. If the first term was 7, the second would be 14, the third would be 21. The 4th would be 28, continue to the 8th term 56.
Answer: x=2
-10 is added to 0 making is 5x=10
Divide 5 on both sides making is x=2
Literally plugging in the time for each value, we can plug in 5 for t to get
22000+(-480*5)=22000+(-2400)=22000-2400=19800
Plugging in 10, we get 22000+(-480*10)=22000-4800=17200. We can turn 22000+(-480*10) into 22000-(480*10) using the distributive property, and adding a negative number to something essentially means to subtract that number.
I challenge you to do t=15 and 20 on your own!
