The shaded region in the graph represents the solution of this system of linear inequalities

y 4x +
y < = x +

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

What is the y-intercept of the line given by the equation

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.
