Answer:
The correct choice is A.
Step-by-step explanation:
The relation which is a function is the one in which none of the first coordinates repeated.
A.
x y
4 -2
5 -3
6 -2
7 -3
We can see that none of the first coordinates repeated in this relation.
Its graph will pass the vertical line test.
It is a function.
Subtract 7 from both sides leaving you with
26=-2a
Divide -2 from both sides leaving to you then with
-13=a and this is the answer
If you only have one line, then both systems are equal to each other. For each x+y=2 and y+x=2 has the solution that are on the same line.
6x^3+13x^2+16 is the result.
Answer:
the problem is the comparison with the calculated time for Jillian and the actual time for Jillian to run the 7 miles. Note: 16% error is the approximate error because the numbers have 2 significant figures stated in the problem.
