Graph the equations to solve the system. y=1/3x-6 y=-1/3x-4 a) no solution: {} b) solutions: all numbers on the line c) one solution: {0,-2} d) one solution: {3,-5}

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

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
