In the figure dhg fhe which statement is true by cpctc

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}
