3x2/5=6/5=

Please I need help with this problem

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above

Find the solution of this system of equation -7x+y=-20 9x-3y=36

The function models the number of accidents per 50 million miles driven as a function
