Answer:

The solution is  x = 9, y = -1.

Step-by-step explanation:

x + y = 8

x -  y = 10       Adding to eliminate y:

2x + 0 = 18

x = 9               Substituting x = 9 into the first equation:

9 + y = 8

y = 8 - 9

y = -1..

Give an example of a quadratic with complex roots. Explain how you know it has complex roots.
Vladimir [108]
2x^2 + x + 3=0 has only complex roots.

The determinant is 1-4*2*3 = -23

-23 (or any determinant) is the part under the square root sign,  If that determinant is negative, knowing you cannot take the square root of a negative number, we know the answers must be complex.

June served 4/9 of 18 liters of fruit punch. How many liters does she have left?
victus00 [196]
She has 10 liters left.  Find 4/9 of 18 by multiplying 4/9 and 18.  4/9 of 18 is 8, so she served 8 of the 18, leaving 10 liters.
