In the barn there are horses and chickens there are 11 heads and 32 legs altogether how many horses are there

Show algebraically that f and g are inverse functions f(x)=x^2/-6; g(x)=square root of 2x+12

Simplify.7x + 3y - 2 + 6x + 1 + y squared 2 you! ; )

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
