>>1st one- at X=0 Y=DNE so the function is not continious.
>>2nd one- there is Y value for every X so the function is continious.
>>3rd one- there is Y value for every X so the function is continious.
>>4th one- f(-1)=1 does not equal the limit of f(x).
because the limit as X aprroaches from the left and from ther right is different.
Answer:
School X has 8 points and School Y has 2 points
Step-by-step explanation:
From first sentence
X - 6 = Y
From second sentence
X = 4Y
Hence substitute equation 1 into equation 2
4Y - 6 = Y
Y = 2
X = 4 x 2 = 8
Answer:
4317 miles
Step-by-step explanation:
At a given speed, distance is proportional to time.
NY-Rome distance = (3500 mi)(7.4 h)/(6 h) = 4316 2/3 mi ≈ 4317 mi
Answer:
x = -6
-18+4y=0 => 4y=18 =>y=18/4=9/2
Y=5
3x+20=0 => x=3x= -20=> x= -20/3
Step-by-step explanation:
