11. Determine if (-4, 6) is a solution for this system
of equations
y = x + 10
2x + y = -2
Is the ordered pair a solution?
Explain how you know:

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

Identify a1 and r for the geometric sequence an= -256(-1/4) n-1

Given that ot =5, xt=12, and ox= 13 is xy tangent to circle o at t? explain.
