Simplify 4y — 4ys + 2y – 5у — 54 – 34

Mathematics
1 answer:
Oxana [17]3 years ago
4 0

Answer:

-4ys + y - 88

Step-by-step explanation:

When we have to simplify equations that have different variables, we always have to look at the like terms, which the like terms are ones that contain the same value and variable. So let's look at our equation :

4y — 4ys + 2y – 5у — 54 – 34

We can see three different terms here :

ys, y, and a constant term.

The rule is that we can only combine two properties that have the same like term, so in the equation :

4y — 4ys + 2y – 5у — 54 – 34

These have the same variable, therefore we can combine like terms.

4y + 2y - 5y

6y - 5y

y

Now implace it into the equation :

y — 4ys — 54 – 34

Onto the next property :

y — 4ys — 54 – 34

This is alone, therefore we can leave it :

y — 4ys — 54 – 34

These two are the same property, so do the following :

-54 - 34

-88

Impace into the equation :

y - 4ys - 88

Now that we have no same common like terms, we can order our equation to greatest value to least :

-4ys + y - 88

1) 3r² – 2r=-9<br> Quadratic formula
Nonamiya [84]

Answer:

Solving the equation 3r^2-2r=-9 using quadratic formula we get: \mathbf{ r=\frac{1+\sqrt{26}\:i}{3}\:or\: r=\frac{1-\sqrt{26}\:i}{3}}

Step-by-step explanation:

We need to solve the equation 3r^2-2r=-9 using quadratic formula.

The quadratic formula is: r=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

For the given equation: 3r^2-2r=-9

We can write it as: 3r^2-2r+9=0

We have a = 3, b= -2 and c=9

Putting values in quadratic formula and finding value of r

r=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\r=\frac{-(-2)\pm\sqrt{(-2)^2-4(3)(9)}}{2(3)}\\r=\frac{2\pm\sqrt{4-108}}{6}\\r=\frac{2\pm\sqrt{-104}}{6}\\We\:know\:that: \sqrt{-1}=i\\ r=\frac{2\pm\sqrt{26} \:i}{6}\\ r=\frac{2+2\sqrt{26}\:i}{6}\:or\: r=\frac{2-2\sqrt{26}\:i}{6}\\ r=\frac{2(1+\sqrt{26}\:i)}{6}\:or\: r=\frac{2(1-\sqrt{26}\:i)}{6}\\ r=\frac{1+\sqrt{26}\:i}{3}\:or\: r=\frac{1-\sqrt{26}\:i}{3}

So, solving the equation 3r^2-2r=-9 using quadratic formula we get: \mathbf{ r=\frac{1+\sqrt{26}\:i}{3}\:or\: r=\frac{1-\sqrt{26}\:i}{3}}
