Hi,
I think this is the table, correct?
Number of Tubes 3 5 7
Cost ($) 12 20 28
we can calculate the prize as the number of tubes multiplied by 4:
3*4=12
5*4=20
7*4=28
which means that one tube costs 4 dollars!
However, in the store A two tubes cost 7, which means that one costs half of this -3.5
So Store B is more expensive (4 dollars per 4 rather than 3.5 as in Store A).
Not a robot! I don't think.
Y in the beginning goes up to 3.
Y in the end goes down to -2 before shooting back up in an infinite sense.
Increasing: The beginning and the end the line on the graph. (Also the jump in the middle, the round part.)
Decreasing: The middle of the graph. (The jump, downward slope.)
Constant, Y at the near end going in a straight line from 9-12 at a -2.
End behavior: Decide for yourself. Is the line going up without fault at the end an appearing continuous or a discontinuous line?
Answer: B (-12, 15)
Step: (3×-4) =-12
And (3×5)= 15
Answer:
4x(2x+3)
Step-by-step explanation:
Since the common factor of 8x^2 and 12x is 4x, put that out and separate the distributed remaining factors.
