Answer:
75
Step-by-step explanation:
Scores for his first tests were 65, 67, 69.
Rate of change: +2
y=2x+63; 63 is the 0th test he took, his first test was 65, so 65-2=63. 2x is the rate of change, his tests scores increase by 2 each time.
x=6, 6th test score
y=2(6)+63
y=12+63
y=75
So, on his 6th test he will get a score of 75
Answer:
$330
Step-by-step explanation:
A simple way to do it is to see that it already has 20 on the graph. 20 is half of 40, so that stands to reason that $165 from 20 hours turns into $330 from 40 hours since it is double the work double the money.
