Answer:

x = -2  ||   y = -3

Step-by-step explanation:

5x - 2y = -4

x + 2y = -8

--------------------------------------------

5x - 2y = -4

5x = -4 + 2y

x = (-4 + 2y)/5

x + 2y = -8

x = -8 - 2y

Solving simultaneously:

-8 - 2y  =   (-4 + 2y)/5

5(-8 - 2y) = -4 + 2y

-40 - 10y = -4 + 2y

-40 + 4 = 2y + 10y

-36 = 12y

y = -3

if y is -3 then x is:

x = -8 - 2y

x = -8 - 2(-3)

x = -2

Below is the graph of a trigonometric function. It has a minimum point at (- 10.4, - 9.8) and a maximum point at (- 3.6, - 1.2)
Vladimir79 [104]

Answer:

13.6

Step-by-step explanation:

The period is double of the distance (on the x-axis) between the maximum and the minimum. In this case, the x-coordinate of the minimum is -10.4, the x-coordinate of the maximum is -3.6, the distance is -3.6 - (-10.4) = 6.8, and the period is 2*6.8 = 13.6
