ANSWER
A. 73
EXPLANATION
The given expression is
![(2{x})^{2} - 3{y}^{2}](https://tex.z-dn.net/?f=%282%7Bx%7D%29%5E%7B2%7D%20%20-%203%7By%7D%5E%7B2%7D%20)
We substitute x=5 and y=3 to obtain:
![(2 \times 5)^{2} - 3{(3)}^{2} = {10}^{2} - 3 \times 9](https://tex.z-dn.net/?f=%282%20%5Ctimes%205%29%5E%7B2%7D%20%20-%203%7B%283%29%7D%5E%7B2%7D%20%20%3D%20%20%7B10%7D%5E%7B2%7D%20%20-%203%20%5Ctimes%209)
This simplifies to,
![= 100 - 27](https://tex.z-dn.net/?f=%20%3D%20100%20-%2027)
![= 73](https://tex.z-dn.net/?f=%20%3D%2073)
The correct choice is A.
Answer:
No
Step-by-step explanation:
in order for a slope to be perpendicularit needs to me the opposite recipricol
so to be perpendicular to 3/2 it would be -2/3
1/3 is the probability that the spinner will stop at the green section since each section is 1/3 of the circle.
Answer:
Critical points are: 2 , -2 and 3.
Step-by-step explanation:
We have been given the expression:
![\frac{x^2-4}{x^2-5x+6}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E2-4%7D%7Bx%5E2-5x%2B6%7D%3C0)
We will factorize the given expression:
Using ![a^2-b^2=(a+b)(a-b)](https://tex.z-dn.net/?f=a%5E2-b%5E2%3D%28a%2Bb%29%28a-b%29)
![\frac{(x+2)(x-2)}{x^2-3x-2x+6}](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%2B2%29%28x-2%29%7D%7Bx%5E2-3x-2x%2B6%7D%3C0)
![\Rightarrow \frac{(x+2)(x-2)}{x(x-3)-2(x-3)}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cfrac%7B%28x%2B2%29%28x-2%29%7D%7Bx%28x-3%29-2%28x-3%29%7D%3C0)
![\Rightarrow \frac{(x+2)(x-2)}{(x-2)(x+3)}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cfrac%7B%28x%2B2%29%28x-2%29%7D%7B%28x-2%29%28x%2B3%29%7D%3C0)
Critical point are those values of an expression when it is equal to zero
Hence, the critical points are: 2,-2 and -3.
