Answer:
Well, I don't think I can remember EVERY skill I was taught through the years but in Kindergarten we used Number Sense so we could accurately... also there's estimation and of course PEMDAS. I've also learned how to round up so that the solution is at least around those numbers if the skill is to be applied.
Step-by-step explanation:
I'm not sure if this'll help but go ahead and have it... just try and change it a bit so they don't get ya for plagirism
Where is the “100” points lie
Answer:
see explanation
Step-by-step explanation:
The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the values that x cannot be.
x² - 4 = 0 ⇒ x² = 4 ⇒ x = ± 2 ← excluded values
domain : x ∈ R, x ≠ ± 2
Answer:
80
Step-by-step explanation:
The two sides of the triangle are the same so the bottom right angle is also 50. 50 + 50 is 100 and 180 - 100 is 80 so x=80. I subtracted 100 from 180 because all the angles in a triangle add up to 180.
multiply the equation by 3
3f(x) = x - 6
x = 3f(x) + 6
x = 3(f(x) + 2)
the answer is A.
