k/3 + 4=10

Given abcd ac=38 and ae=3x+4 find the value of x

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1

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}.
