What is the next number in the following sequence: 1,4,9,16,25,__

36

Step-by-step explanation:

1, 4 , 9 , 16 , 25

These are all squares of 2, 3, 4, and 5.

From this pattern, the next square would be of 6 so 6^2 = 36

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
