Solve the system of equations -5y+8x=-18 5y+2x=58

(x,y) = (4, 10)

Step-by-step explanation:

-5y + 8x = -18

5y +2x =58

Adding both equations

-5y + 8x = -18

5y  + 2x = 58

0   + 10x = 40

    10x/10  = 40 / 10

     x = 4

putting x= 4 in equation 1

-5y + 8x = -18

-5y + 8(4) = -18

-5y + 32 = -18

-5y = -18 -32

-5y = -50

-5y/-5 = -50/-5

y= 10

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.

step-by-step explanation:

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
