What is the solution set of x+4/2x-1 <0

prisoha [69]

Answer: x=1/3

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

3x−1<0

Step 2: Add 1 to both sides.

3x−1+1<0+1

3x<1

Step 3: Divide both sides by 3.

3x/3 <1/3

x/1/3

What if this function simplified?

almond37 [142]

Hi!

Let's first expand the cotangent of theta.

You'll probably know that tangent will be "y/x", or $\frac{sin(x)}{cos(x)}$ , and cotangent is the reciprocal of this, meaning that it is "x/y" or $\frac{cos(x)}{sin(x)}$ .

That means that we are now given this equation.

$cos(x)\frac{cos(x)}{sin(x)}+sin(x)$

That'll multiply to:

$\frac{cos^2(x)}{sin(x)}+sin(x)$

We'll want a common denominator to add by multiplying $sin(x)$ to both top and bottom of the second term:

$\frac{cos^2(x)}{sin(x)}+\frac{sin^2(x)}{sin(x)}$

$\frac{cos^2(x)+sin^2(x)}{sin(x)}$

Pythagorean Identity states that $sin^2(x)+cos^2(x)=1$ , so substitute that in:

$\frac{1}{sin(x)}$

Which simplifies to:

$csc(x)$

Hope this helps!

Factorize the polynomial: 6q^2 – q – 12.

Ksivusya [100]

Answer:

Step-by-step explanation:

What two number multiply to equal 6*(-12) and add to equal -1? That is -9 and +8.

$6q^2-9q+8q-12$

Now factor by grouping

$(6q^2-9q)+(8q-12)\\3q(2q-3)+4(2q-3)\\(3q+4)(2q-3)$
