Use this for the following questions. During their last game, the Miami Dolphins scored 6 times for a total score of 30 points. They scored 7 points for each touchdown and 3 points for each field goal.

Write a system of equations for the situation.

Hint: use x for the number of touchdowns and y for the number of field goals.

Equation 1:

Equation 2:

What is the solution to the system you wrote in question 1?

Solution:

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

do your own work and don"t cheat.
