Answer:
x=0
y=4
Step-by-step explanation:
x=8-2y
3y=-x+12
first make it
ax ( + or - ) by = c
x+2y=8
x+3y=12
now subtract the equations
x+2y=8
- (x+3y=12)
-----------------
-1y=-4
y=4
x+2(4)=8
x+8=8
x=0
7/12 - ( 1/3 + 1/6 ) = 7/12 - 1/3 - 1/6
= 7/12 - 1/3(4) - 1/6(2)
= 7/12 - 4/12 - 2/12
= (7 - 4 - 2)/12
= 1/12
Answer: 1/12
Ok done. Thank to me :>
Probability is 0/12 since there are no blue lollipops in the bag.
In B 5^2 = 25. There is no x anywhere.
In C f(x) = 2/x is a function of a reciprocal, not a quadratic.
In D f(x) = 2x^3 + 3x^2 - 5 is a cubic. A cubic is not a quadratic. The highest power of a quadratic is x^2
That leaves A. When you expand the brackets, you get
3(x^2 + 3x- 4x - 12)
2(x^2 - x - 12) when you remove the brackets you get
2x^2 - 2x - 24. The highest power of x is x^2. This is your quadratic.
A<<<< answer.
