The graph of 6x + 4y = −2 is shown on the grid. which ordered pair is in the solution set of 6x + 4y ≤ −2?
a) (2, 3)
b) (3, 2)
c) (−2, −3)
d) (−2, 3)

C

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
