Use the associative property to simplify the expression. 43 + 30 + 70 O A. 43 + 10(3 + 7) = 43 + 10(10) = 143 OB. 43 + (30 + 70) = 43 + 100 = 143 O C. 43 + 30 + 70 = 73 + 70 = 143 O = D. 43 + 70 + 30 = 113 + 30 = 143

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.
