Find the measures of the angles.
a. m∠x
b. m∠y
a. m∠x = 50°
m∠y = 135°
b. m∠x = 125°
m∠y = 50°
c. m∠x = 50°
m∠y = 125°
d. m∠x = 135°
m∠y = 50°

What is the most accurate measurement of 1 pound

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 each quadratic equation by factoring and using the zero product property. 14x - 49 = x^2
