4. b=2m-a

Use the properties of equality to complete each proof

Which shows the correct solution of the equation 1/2a+2/3b=50, when b=30?

If a || b and b | y, then ? a) x || y. b) x | a. c) a | y. d) a || y.

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
