Choose the equivalent system of linear equations that will produce the same solution as the one given below. (1 point) 4x − 2y = 6 2x + y = 5 −4x − 2y = 10 −4y = 4 −4x − 5y = −1 −7y = 5 3x + 2y = 6 7x = 12 4x + 2y = 10 8x = 16

If 1 is divided by the sum of y& 4.the result is equal to 3 divided by 4, find the value of m

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
