What is the solution to y in the inequality 4(x+y)-10≥x+6y-4

nikklg [1K]

Answer:

y ≤ 3/2 x - 3.

Step-by-step explanation:

4(x + y) - 10 ≥ x + 6y - 4

4x + 4y - 10 ≥ x + 6y - 4

4y - 6y ≥ x - 4x - 4 + 10

-2y ≥ -3x + 6

y ≤ 3/2 x - 3. (Note the inequality sign is reversed because we are dividing by a negative value)).

Which of the polynomial equations cannot be solved using the quadratic formula?

xxMikexx [17]

Answer:

The polynomial equation that cannot be solved using the quadratic formula: Option2: $x^2-2x^3-5=0$

Step-by-step explanation:

First of all we have to learn what a quadratic polynomial is.

A polynomial or equation of degree 2 is called a quadratic equation. Quadratic formula is used to solve quadratic equations.

The quadratic equation is of the form:

$ax^2+bx+c = 0$

From the given options, only option 2 doesn't have degree 2 so it is not a quadratic polynomial.

Hence,

The polynomial equation that cannot be solved using the quadratic formula: Option2: $x^2-2x^3-5=0$
