Write the first 3 terms of the sequence below. Tn= n squared+5n+2 Thanks! Brainliest to first (correct) answer!

8, 16, 26

Step-by-step explanation:

To find the first 3 terms substitute n = 1, 2, 3 into , that is

= 1² + 5(1) + 2 = 1 + 5 + 2 = 8

= 2² + 5(2) + 2 = 4 + 10 + 2 = 16

= 3² + 5(3) + 2 = 9 + 15 + 2 = 26

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
