Answer:
x = -3 is the point of discontinuity.
Hence, option B is correct.
Step-by-step explanation:
Given the expression
In order to determine the discontinuity, the denominator must be 0.
so let us solve the denominator to get the values of x
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
Subtract 3 from both sides
Therefore, x = -3 is the point of discontinuity.
Hence, option B is correct.
It’s the last one
i just used guess and check haha
Answer:
a) 6 17/20
b) 10 31/60
Step-by-step explanation:
a) 9 2/20 - 2 1/4 = 137/20 = 6 17/20
b) 6 17/20 + 3 2/3 = 631/60 = 10 31/60
Ah this kind of question is great! There's a strange and lovely relationship between repeating decimals and constants divided by 9 (or 99 or 999). An explanatory example is ".777777..." which can actually be expressed as 7/9. And ".09090909..." can be expressed as 09/99 or 1/11.
