Solve the following system of equations and show all work. y = 2x2 y = –3x −1

For this case we have a system of two equations with two unknowns:

Matching we have:

We have a quadratic equation of the form

Where:

Applying the quadratic formula we have:

Substituting:

We have two roots:

Now, we look for the values of y, substituting in any of the equations:

ANswer:

step-by-step explanation:

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
