Step-by-step explanation:
Answer:
6 packages.
Step-by-step explanation:
If they are $3 each, and you only have $18, divide 18 by 3, which gives you 6.
X^2-2x -3 =0
a =1 b =-2 and c = -3
x = - (-2) +/- sqrt (-2)^2 - 4(1)(-3)
--------------------------------------
2(1)
x = + 2 +/- sqrt [(4) - 4(-3)]
-------------------------------
2
x = +2 +/- sqrt [4 + 12]
--------------------------
2
x = +2 +/- sqrt[16]
-------------------
2
x = +2 +/- (4)
-------------
2
x = 2 + 4 or 2 -4
------- ------
2 2
x = 6/2 or -2/2
x = 3 or x = -1
The second number in an ordered pair is the y-coordinate and corresponds to a number on the y-axis.
