Question

the pair of equations Y is equal to zero and Y is equal to minus 7 has
a) one solution
b) 2 solution
c) infinitely many solution
d) no solution​
plz explain.

Answer 1

Step-by-step explanation:

Given The pair of equations Y is equal to zero and Y is equal to minus 7 has

a) one solution

b) 2 solution

c) infinitely many solution

d) no solution​

• Given the pair of equations y = 0 and y = - 7
• Now the equation of the line y = 0 lies on x – axis itself and the other equation y = 7 is parallel to x- axis .
• Since, these lines are parallel, they do not have any common solution.
• When a graph is plotted we find both the lines are parallel.
• So no solution will be the correct option

Answer 2

Pair of equation has no solution, so option d is correct.

Step-by-step explanation:

• Given data

        Equation of first line

        Y = 0

        This can be written as

        0 X + 1 Y = 0     ...1)

• Equation of second line

        Y = - 7

        This can also be written as

        0 X + 1 Y = - 7      ...2)

• It is clear that both line do not intersect with X- axis.

• From equation 1) and equation 2) ,We see that both line are parallel to each other. So it will never intersect to each other. So there are no solutions.
