9514 1404 393

Answer:

  71.447296

Step-by-step explanation:

The sequence is geometric with first term 100 and common ratio -0.4. Then the sum of n terms is ...

  Sn = 100(1 -(-0.4)^n)/(1 -(-0.4))

and the sum of 9 terms is ...

  S9 = 100(1 -(-0.4^9))/(1.4) = 71.447296

Solve the inequality below. Use the drop-down menus to describe the solution and its greah
Solnce55 [7]

Answer:

The solution of the inequality is x ≤ -4. A graph of the solution should have a vertical line passing through x = -4 and be shaded to the left of x = -4

Step-by-step explanation:

-7x + 13 ≥ 41

Subtract 13 from both sides

-7x ≥ 28

Dividing both sides by the -7 changes the inequality sign and we have

x ≤ -4

Hence, the solution of the inequality is x ≤ -4 and the graph of the solution should have a vertical line passing through x = -4 and it should be shaded to the left of x = -4 indicating that only numbers less than or equal to -4 are possible solutions of the inequality.

Hope this Helps!!!
