Answer:
Equation C: 5/8x + 2..5 = 3/8x + 1.5 + 1/4x
Step-by-step explanation:
Let us go through each of the equations one by one.
Equation A: 
This simplifies to

which has infinitely many solutions.
Equation B: 
this simplifies to


which is exactly one solution.
Equation C: 
this simplifies to


There's no way this is going to be possible; this equation has no solutions.
Equation D: 
this gives


which is exactly one solution.
Thus we see that it is equation C that has no solutions.
The illegal values of b are when the denominator equals 0.
So,
gives you (b-4)(b+2)=0
Therefore, b=4 and b=-2, which is answer A.

Step-by-step explanation:
Step-by-step explanation:
<u>According to given table we have pairs of points:</u>
- (4, 6.00), (5, 8.25), (6, 10.50)
<u>The rate of change is:</u>
- (8.25 - 6.00)/(5 - 4) = 2.25
or
- (10.50 - 8.25)/(6 - 5) = 2.25
<u>It is 2.25 and the meaning is:</u>
