If a b and c are three different numbers which of the following equations has infinitely many solutions a. ax=bx+c
b. ax+b=ax+c
c. ax+b=ax+b

c. ax+b=ax+b

Step-by-step explanation:

To know what equation has infinite solutions, you first try to simplify the equations:

a.

In this case you have that a must be different of b, but there is no restriction to the value of c, then c can be equal to a or b.

b.

Here you obtain that b = c. But the statement of the question says that a, b and c are three different numbers.

c.

In this case you have that whichever values of a, b and are available solutions of the equation. Furthermore, when you obtain 0=0, there are infinite solutions to the equation.

Then, the answer is:

c. ax+b=ax+b

the answer to the question is a  

it has the same slope and the same y-intercept.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
