PLEASE HELP For which equation is x= 4 not a solution?
A 5x-6=14
B 13-3x=x/4 C x/8 +8=9
D. 7- 3x = -5

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12

Which set of lengths could represent the sides of a triangle? a. 3, 7, 10 b. 4, 5, 10 c. 6, 8, 14 d. 12, 6, 7

Find the directions in which the function increases and decreases most rapidly at upper p 0p0. then find the derivatives of the function in these directions. f(x,y)equals=x squared plus xy plus y squaredx2+xy+y2, upper p 0p0left parenthesis 1 comma negative 4 right parenthesis
