Answer:

\frac{10a+300}{200}

Step-by-step explanation:

1. take 10 times a and get 10a and put in the numerator spot of your answer

2. then do 15 times 20 which is 300 so add 300 to 10a in the numerator spot of your answer

3. multiple 20 times 10 which is 200 and make it your denominator of your answer

This method is called the butterfly method

What is an equation of the line that is perpendicular to y- 4 = 2(x-6) and
Ludmilka [50]

Answer:

D. Y+5=-(1/2)*(x+3)

Step-by-step explanation:

Perpendicular Lines are those with the following condition:

y=a*x+b (1)

y=c*x+d (2)

Where 'a' and 'c' are the respective slope

If These two lines are perpendicular, then

a=- 1/c

Equation (1) for our case is written as y=2x-8, meaning that a=2 and b = -8

Using those principles we have that the slope for our needed line ('c') has to be -(1/2).

Now we most use the given point to find the remaining term of the equation (d) so, evaluate (-3,-5) in eq (2) to have this:

-5=(-1/2)*(-3)+d

resulting that d=-5-(3/2)

Eq (2) is written now as the following: y= (-1/2)*x - (5+3/2)

Rearranging terms, we have the following:

y+5=(-1/2)*x-(3/2)

where you can obtain a more pretty expression:

y+5=(-1/2)*(x+3)
