Answer:
No
Step-by-step explanation:
substitute -2 for 'x' and 5 for 'y'
2(-2) + 5(5) = 0?
-4 + 25 = 21, not 0
Answer:
(3x -1) (3x+1)
Step-by-step explanation:
9x^2 - 1
Rewriting
(3x)^2 -1^2
This is the difference of squares a^2 -b^2 = (a+b) (a-b)
(3x -1) (3x+1)
Answer: Option b.
Step-by-step explanation:
1. You can rewrite it as following:
This means that you must substitute x=-6 into the limit. There is not x, then the function is always equal to 2, no matter the value of x.
This means that you must substitute x=-6 into the limit. There is not x, then the function is always equal to 1, no matter the value of x.
2. Then:
3. The answer 2.
Answer:
In terms of probablity (A - appetizer oredered, B - desert ordered)
P(A)=63%
P(B)=40%
P(AorB)=76%.
Using the formula:
P(AorB)=P(A)+P(B)-P(A&B) we get P(A&B)=63%+40%-76%=27% (probability we were looking for).
