Joseph solved the system of equations {2x + 5y = 3 as shown. {2x + 5y = 3 3x + y = 11 → y = −3x + 11 3x + (−3x + 11) = 11 11 = 11 There are infinitely many solutions. What is Joseph's error? Explain.

The parabola x= √y-9 opens: a.)up b.)down c.)right d.)left

Which functions shave a maximum and are transformed to the left and down of the parent function ,check all that apply f(x) = x2? p(x) =14 (x+7)2 + 1

Offering 30 if a plus b plus c equals 68 and ab plus bc plus ca equals 1121, where a, b, and c are all prime numbers, find the value of abc. the answer is 1978 but i need an explanation on how to get that.
