Find the equation of the line that is perpendicular to y = 1/4x – 2 and passes though the point (5, –2). A) y = –1/4x + 18 B) y
Mashcka [7]

Since our line is perpendicular to this line, the slope of

our line is the negative reciprocal of 1/4, which is -4/1.

Remember, negative reciprocal is just a fancy way

of saying flip the fraction and change the sign.

So the slope of our line is -4/1 and we use this slope along

with our given point to write the equation of our line.

Start with the point-slope formula.

Y - y1 = m(x - x1).

~Substitute

Y - -2 = -4/1(x - 5).

Minus a negative is plus a positive.

Y + 2 = -4/1x + 20.

Subtract 2 from both sides.

Y = -4/1x + 18

So, our answer is C.

Can someone plz help me now plz
Tcecarenko [31]

Answer:

Step-by-step explanation:

Write down what you have for each pizza size.

small: s

Medium: (3/2) s

Large: (5/2) s

The only way I can see to do this is

s = L - M

s = 5/2 s  -   3/2 s

s = 2/2 s

This of course is not exactly what you are looking for. There is no explicit formula that will tell you exactly how much dough is in a small pizza.

See the comment below posted by SqdanceFan. He is saying that M/L = (3/2)//(5/2) = 3/5

Also (M)/( S + M)  =  3/5

But neither gives you an explicit formula for small, but it is a relationship. The fact that equality is achieved when both are zero is also true, but it does not solve the question. I don't think there's a good answer to this question.
