Step-by-step explanation: So the mean is the same thing as the average. To find the mean you add up all of the numbers, and then divide by 5 because there are five numbers. So the sum would be 27,290. Then that divided by 5 would be 5458.

Which is the solution of this system of equations? y=5x−83y=x+18<br><br> y+5(3)=15

Ulleksa [173]

Answer:

y=5x−83y=x+18 (the question is wrong; it has 2 equal signs)

y+5(3)=15

y+15=15 (multiply 5*3; you get 15)

y= 15-15

y= 0

alexandr1967 [171]

Answer:

The first six numbers are $-2,1,-2,1,-2,1$

Step-by-step explanation:

First term is $-2$

The term to term rule is 'square and subtract $3$ '

Second term $=(-2)^{2} -3=1$

Third term $=(1)^{2} -3=-2$

Fourth term $=(-2)^{2} -3=1$

Fifth term $=(1)^{2} -3=-2$

Sixth term $=(-2)^{2} -3=1$

The first six numbers are $-2,1,-2,1,-2,1$
