What is the solution to the system of equations?

4x-8y=-16

x-2y=-8

a. use the substitution method to justify that the given system of equations has no solution.
b. what do you know about the two lines in this system of equations?

No solution

Step-by-step explanation:

from the second equation x = -8 + 2y

By substituting in the first equation 4(-8 + 2y) -8y = -16

-32 +8y -8y = -16

-32 = -16

the left hand side not equal the write and side

So there is no solution for the system of equations

means the two lines are parallel

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
