-5/13
Formula: Y2-Y1/X2-X1
Answer:
2 touchdowns, 3 field goals
Step-by-step explanation:
The number of touchdowns cannot be more than 3, so it is relatively easy to find the solution by trial and error.
23 is not divisible by 3, so 0 touchdowns is not a solution
23 -7 = 16 is not divisible by 3, so 1 touchdown is not a solution
23 -14 = 9 is divisible by 3, so 2 touchdowns and 3 field goals is a solution
21 -21 = 2 is not divisible by 3, so there is only one solution.
This system will have 1 solution, or C. That's because since the equations are different, meaning that there is 1 solution.
25 a month x 12 months= 300
300+50= 350
56 weeks x 3 times a week= 168
350/168= 2.08 each visit
