Explain how we do decimals plus Fractions

You can convert the fractions into a decimal, or a decimal into a fraction. I find that fractions into decimals is easier because with fractions you have the added step of making sure the two numbers have the same denominator.

Also, if you type in the numerator of the fraction divided by the denominator into a calculator, it will automatically give you the decimal. It is a lot harder to convert decimal into fractions if your calculator doesn’t do it.

Answer:

You have to either make the fraction a decimal, or you have the decimal a fraction. Also when making it into a fraction, you should have the same denominator.

(x+2)(2x+1)+(x+2)(2x-3) factorizar

koban [17]

Answer:

(x + 2)(4x - 2).

Step-by-step explanation:

(x+2)(2x+1)+(x+2)(2x-3)

Note that (x + 2) is common to 2 parts of the expression. So we have:

(x + 2)(2x + 1 + 2x - 3)

= Ix + 2)(4x - 2)

A line passes through (3, -2) and (6,2). Write an equation for the line in point-slope form.

snow_lady [41]

Answer:

4x - 3y -18 = 0 or y = 4x/3 - 6

Step-by-step explanation:

We will have to find the slope of the line first

The formula for slope:

$m =\frac{y_{2}- y_{1} }{x_{2} -x_{1} } \\m= \frac{-2-2}{3-6}\\ =\frac{-4}{-3}\\ =\frac{4}{3}$

The standard form of equation of a line is:

y = mx + b

We know m,

So the equation will be:

$y= \frac{4}{3}x+b$

We have to find the value of b, for that we will put any one of the point in the equation

So, putting (6,2)

2 = 4/3 * 6 + b

2 = 8 +b

b = -6

Putting the value of m and b in the standard form of equation of line,

$y = mx + b\\y = \frac{4}{3}x+(-6)\\y = \frac{4}{3} x - 6\\Multiplying\ both\ sides\ by\ 3\\3y = 4x - 18\\4x - 3y -18 = 0$ ..
