3. From the beginning of a trail, Claire hiked 4 3/8 to the lake. Then she hiked 2 5/8 to the nature center. Is 5 miles, 6 miles, or 7 miles the most reasonable estimate for how far Claire hiked altogether?​

Aregression was run to determine if there is a relationship between hours of tv watched per day (x) and number of situps a person can do (y). the results of the regression were: y=ax+b a=-0.662 b=30.418 r2=0.703921 r=-0.839

What are the solutions of the system? y = x^2 + 2x +3y = 4x - 2a. (-1, -6) and (-3, -14)b. (-1, 10) and (3, -6)c. no solutiond. (-1, -6) and (3, 10)

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
