What is the solution set for this linear-quadratic system of equations?

y= x2 - x-12

y-x-3 = 0

A. {(-3,0), (0,3)}

B. {(-3,0), (4, 0);

C. {(-3,0), (5,8)}

D. {(4,0), (0,3)}

C

Step-by-step explanation:

Given:

To find: solution set for this linear-quadratic system of equations

Solution:

A linear equation is an equation whose degree is 1 and degree of quadratic equation is 2.

Put in

For x = -3, y = -3+3=0

For x = 5, y = 5 + 3 = 8

So solutions are

Option C. is correct

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
