I'm going to assume you meant to say
Factorize the denominator to reveal a removable discontinuity in the limand:
In the limit, we're considering values of x *near* -4, and not x = -4 itself. So we can cancel the factors of x + 4 and we're left with
Answer:
a. y=x+1
b. x=-3
Step-by-step explanation:
a. slope= (6-4)/(5-3)=1
substitute (5,6) to y=1x+b; b=1
therefore, y=x+1
b. x=-3
Answer:
4 years
Step-by-step explanation:
The exponent of 0.5 is 1 when t=4. So, half the original amount will be remaining when t=4.
3/11 x 5/11
15/121 would be the probability. I am not sure if it can simplify any more! :)
