If you have two statements p and q and
![p\Rightarrow q](https://tex.z-dn.net/?f=p%5CRightarrow%20q)
is
true, then
![\neg q\Rightarrow \neg p](https://tex.z-dn.net/?f=%5Cneg%20q%5CRightarrow%20%5Cneg%20p)
is also true.
In your case, statements are p - "x is odd" and q - "2x is even".
Then
![\neg p](https://tex.z-dn.net/?f=%5Cneg%20p)
- "x is not odd" and
![\neg q](https://tex.z-dn.net/?f=%5Cneg%20q)
- "2x is not even."
Hence
![\neg q\Rightarrow \neg p](https://tex.z-dn.net/?f=%5Cneg%20q%5CRightarrow%20%5Cneg%20p)
sounds as: "If 2x is not even, then x is not odd".
Answer: correct choice is D.
Step-by-step explanation:
the rate of change in A
10-5/4.5-3 .5
=5.
but where is the function B??
just pick two y values and it's corresponding x values
the rate of change is equal to the gradient .
change in y values divided by change in the x values.
Answer:
x=2/3 or x=−1/2
Step-by-step explanation:
6x²−x=2
6x²−x−2=2−2
6x²−x−2=0
(3x−2)(2x+1)=0
3x−2=0 or 2x+1=0
x=2/3 or x=−1/2
The answer is b
There is no solution to the problem because it just doesn’t make sense. You can not add to sides with so many variables and expect to get a answer
Answer:
20° and 30°
Step-by-step explanation:
the sum of the 4 angles in a quadrilateral = 360°
given 2 angles are 200° and 110° , then remaining 2 angles sum to
360° - 200° - 110° = 360° - 310° = 50°
sum the parts of the ratio, 2 + 3 = 5 parts , then
1 part = 50° ÷ 5 = 10° , so
2 parts = 2 × 10° = 20°
3 parts = 3 × 10° = 30°
the two angles are 20° and 30°
