Answer:
1 solution
Step-by-step explanation:
This is a linear equation and has one solution
6x - 4 = x + 6 ( subtract x from both sides )
5x - 4 = 6 ( add 4 to both sides )
5x = 10 ( divide both sides by 5 )
x = 10 ← only 1 solution
Answer:
1500
Step-by-step explanation:
The average rate of change of a function on the interval [a, b] is given by ...
rate of change = (f(b) -f(a))/(b -a)
On the interval [7, 9], the average rate of change is ...
(5760 -1920)/(9 -7) = 3840/2 = 1920
On the interval [4, 6], the average rate of change is ...
(945 -105)/(6 -4) = 840/2 = 420
The rate of change on the first interval is greater by ...
1920 -420 = 1500
No. If there are two of the same x, it’s not a function.

1. Yes he would be able to but the back pack and he would actually have 18 to spare. Explanation- he saves $9 a week so if he saves for 7 weeks then he will have $63 but since he only needed 45 he will have 18 to spare
2. Since they have 65.50 but need to have 180 then u could just subtract 180 from 65.50 so they would 114.5 more dollars
3. Since lee scored 4 FEWER this tells us that micheal has more points so you would just add 4 to micheals total of points which would give you that micheal had 22 points
