1)   (1, -2) >Last option

2)  (-3/4 , -1/5) > First option

Step-by-step explanation:

1)

8x + 2y = 4      (1)

-4x + 3y = -10  (2)

Multiply equation(2)  by 2

2(-4x + 3y)  = 2(-10)

-8x + 6y = -20

So now you have

8x + 2y = 4

-8x + 6y = -20

add

8y = -16

 y = -2

Substitute y = -2 into 8x + 2y = 4

8x + 2(-2) = 4

8x - 4 = 4

8x = 8

 x = 1

Solution (1 , -2)

2)

8g - 5h = 7 (1)

4g + 10h = 1 (2)

Multiply equation(2)  by -2

-2(4g + 10h)  = -2(1)

-8g - 20h = -2

Now you have 2 equations

8g - 5h = 7

-8g - 20h = -2

add

-25h = 5

    h = -1/5

Substitute h = -1/5 into 8g - 5h = 7

8g - 5(-1/5) = 7

8g + 1 = 7

8g = -6

 g = -3/4

Solution (-3/4 , -1/5)

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
