Answer:

\dfrac{2}{5m}-\dfrac{4}{5}-\dfrac{3}{5m} is equivalent to:

-\dfrac{1}{5m}-\dfrac{4}{5}

Step-by-step explanation:

we have to simplify the expression:

\dfrac{2}{5m}-\dfrac{4}{5}-\dfrac{3}{5m}

On combining the like terms, we get

\dfrac{2}{5m}-\dfrac{3}{5m}-\dfrac{4}{5}

= \dfrac{2-3}{5m}-\dfrac{4}{5}

= -\dfrac{1}{5m}-\dfrac{4}{5}

Hence, \dfrac{2}{5m}-\dfrac{4}{5}-\dfrac{3}{5m} is equivalent to:

-\dfrac{1}{5m}-\dfrac{4}{5}

What is the equation of a line that passes through the point (2, 7) and is perpendicular to the line whose equation is y=x/4+5 ?
worty [1.4K]

Answer:

y = -4x+15

Step-by-step explanation:

y=x/4+5 may be presented as y = 1/4 x + 5, where a=1/4, b=5

swapping numerator and denominator and inserting an opposite sign in a=1/4, we have:

1/4 --------> 4/1 -------> -4/1 = -4

y = -4x+n

Point (2,7) means that x=2, y=7 substitute it to the equation y=-4x+n, calculate "n":

7=-4*2+n ------>    7=-8+n ------->   7+8 = n -------> 15=n

substituting n=15 to the equation y=-4x+n, we get finally y=-4x+15

ladessa [460]

Answer:

0 or 6x+4=6x+4  (Technically no slope at all!!)

Step-by-step explanation:

You need to do distributive property and then solve for x!!

meaning the 2(3x+2) has to get distributive property process.

6x+4=6x+4

That shall be equal together!!! (You could stop here!!)


If continue:

In a large county in Central Pennsylvania, 42% of all registered voters are Democrats and 53% are Republicans. What is the proba
AVprozaik [17]

Answer:

Probability [Randomly selected voter affiliated with other party] = 1/20

Step-by-step explanation:

Given:

Percentage of Democrats voters = 42%

Percentage of Republican voters = 53%

Find:

Probability [Randomly selected voter affiliated with other party]

Computation:

Percentage of other party voters = 100% - [Percentage of Democrats voters + Percentage of Republican voters]

Percentage of other party voters = 100% - [42% + 53%]

Percentage of other party voters = 100% - 95%

Percentage of other party voters = 5%

Probability [Randomly selected voter affiliated with other party] = Percentage of other party voters / 100%

Probability [Randomly selected voter affiliated with other party] = 5% / 100%

Probability [Randomly selected voter affiliated with other party] = 1/20
