Line L has an undefined slope. Line M is perpendicular to line L. Which of the following could be the equation of line M?

1 answer:

6 0

"Line L has an undefined slope" so line L is any vertical line.

Anything perpendicular to this vertical line will be horizontal. So line M is horizontal.

Horizontal lines are of the form y = k for some fixed number k. The only thing that fits is choice B) y = 7 where k = 7 in this case.

Choice A graphs out a diagonal line, choice C graphs a vertical line, while choice D graphs out a hyperbola. These facts are why we can eliminate these non-answers.

Answer: Choice B) y = 7

A box contains 15 lbs.of books. There are 20 books in the box. How much does each book weigh?

Setler79 [48]

Answer:

0.75 lbs.

Step-by-step explanation:

Okay, this one is more simple. To find the weight of each book, You have to solve this division problem:

15/20

If you divided it the other way around, you would be saying each book weighed 1.33 pounds. That wouldn't be correct because then you would have over 20 lbs. of books, when you only have 15.

So, the answer is 0.75 pounds.

Can someone answer this question please answer it correctly if it’s corect I will mark you brainliest

Salsk061 [2.6K]

Let's put all of these into percent form.

P(Guilty) = 0.25 = 25%

P(Innocent) = 55%

P(Retrial) = 1/5 = 0.2 = 20%

Next, we need to order them from least to most likely. The least likely event to occur would be the smallest percent, then the next smallest, etc.

Order: Retrial, Guilty, Innocent

Hope this helps! :)

Mandy is building a rectangular garden pond with the area of 12ft^2. The length of pool needs to be 2 ft more than twice the wid

Genrish500 [490]

The length of rectangular pool is 6 ft and width of rectangular pool is 2 ft.

Step-by-step explanation:

Given,

Area of rectangular pool = 12 square feet

Let,

Width of pool = w

Length of pool = l = 2w+2

Area = Length * Width

$12=(2w+2)*w\\12=2w^2+2w\\2w^2+2w-12=0$

Dividing each term by 2;

$\frac{2w^2}{2}+\frac{2w}{2}-\frac{12}{2}=0\\w^2+w-6=0\\w^2+3w-2w-6=0\\w(w+3)-2(w+3)=0\\(w+3)(w-2)=0\\$

Either,

w+3 = 0 => w=-3

Or,

w-2=0 =>w=2

As width cannot be negative, therefore,

Width of rectangular pool = 2 ft

Length of rectangular pool = 2w+2 = 2(2)+2 = 4+2 = 6 ft

The length of rectangular pool is 6 ft and width of rectangular pool is 2 ft.
