Answer:
Move all terms that don't contain y to the right side and solve.y=4−6x/5
Step-by-step explanation:
The solution to this inequality is 4 < x or x > 4.
In order to solve this, follow the steps to solving an equation with one variable. The steps are below for you.
2x + 8 < 5x - 4 ------> Subtract 2x from both sides
8 < 3x - 4 -----> Add 4 to both sides
12 < 3x -----> Divide both sides by 3
4 < x
4(x + 9) + 5x = 9x - 36
=> 4x + 36 + 5x = 9x - 36
=> 9x + 36 = 9x - 36
=> 9x - 9x = -36 - 36
=> 0 = -72
You can see that the equation doesn't hold true.
So there is no solution for this equation.
Answer is C. no real solutions
Answer:
On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42?
That turned out to be much harder—as in, no one was able to solve for those integers for 65 years until a supercomputer finally came up with the solution to 42. (For the record: x = -80538738812075974, y = 80435758145817515, and z = 12602123297335631. Obviously.)
