Mathematics

7 0

Answer:

In bold below.

Step-by-step explanation:

a)  Arithmetic sequence with common difference 3 and first term = 2:

nth term =  2 + 3(n - 1)

= 3n -1.

b)  Similar to above with common difference 2 and first term = 9.

nth term = 9 + 2(n - 1)

= 2n + 7.

Noah plays football. His team's goal is to score
OleMash [197]

Answer:

No

Step-by-step explanation:

We can plug in the ordered pair (6,-1) into the equation. Remember that 6 is the x coordinate therefore we plug it in for x and that -1 is the y coordinate so we should plug it in for y.

6x+3y=6(6)+3(-1)=36-3=33

Since 33 is not equivalent to 15, (6, -1) is not a solution to the equation.
