Answer:
we have 2 real solutions
Step-by-step explanation:
ax^2 + bx+c
discriminant
b^2-4ac
6x=-2x^2-3
subtract 6x from each side
0 = -2x^2 -6x-3
a= -2
b=-6
c=-3
b^2-4ac = (-6)^2 - 4(-2) (-3)
36 - 24
12
if > 0 2 real solutions
= 0 1 real solution
< 0 2 complex solution
since 12 > 0 we have 2 real solutions
If you would like to solve 9 <= 17 - 4x for x, you can do this using the following steps:
9 <= 17 - 4x
4x <= 17 - 9
4x <= 8 /4
x <= 8/4
x <= 2
The correct result would be x <= 2.
Answer:
Your wrong, it’s B.
X axis = Number of Bottles of water sold
Y axis = Number of dollars collected
So, (x,y)
That means, (Number of Bottles of water sold,Number of dollars collected)
Finally, (10,20) means he sold 10 bottles of water for $20.
Hope that helped!
Step-by-step explanation:
The property of 16 + 31 = 31 + 16 is called Commutative Property.
The property states that the order does not matter. This includes both multiplication and addition. Other examples include 4 + 2 = 2 + 4, or even 10 + 9 + 3 = 3 + 9 + 10. In easier words, the problem is just the backwards version of the original problem.
