Hello!

Let's plug in the numbers into each function and see which one is true. We will use the F(n) value of 11 and the n value of 2.

A. 11=6+5 True
B. 11=2+5 False
C. 11=8 False

Our answer is A. F(n)=3n+5

I hope this helps!

It's A. all you need to do is plug in the "n"-values for each equation and see if it is true. the only one that works is answer A.

I got (-6.28, -0.76).

Step 1.) Write out the problems
-2x=8-6y
-15x=21-6y

Step 2.) Pick a problem and solve for X
-2x=8-6y = x=-4-3y

Step 3.) Plug in the x
(-15)(-4-3y)= 21-6y
60 + 45y= 21-6y

Step 4.) Solve for y
y=-0.76

Step 5.) Plug in the y value into one of the equations
-2x= 8- 6(-0.76)
-2x= 8 + 4.56
x= -6.28

Step 6.) Check your answers
-2(-6.28)=8-6(-0.76)
12.56=12.56

Step 7.) Write it out
(-6.28,-0.76)
