QUESTION 1) Line M passes through the points (-4, -11) and (3, 3). Line N passes through the points (5, -2) and (-6, 9). Which o
7nadin3 [17]

Answer:

Yes, lines M and N intersect because their slopes are different.

Step-by-step explanation:

First, we can start out by finding the slope of Line M and Line N. The slope formula is (y_2 - y_1)/(x_ 2- x_1)

Slope of Line M:

(3--11) / (3--4)

(3+11) / (3+4)

14/7

2

Now we know that the slope of Line M is 2.

Slope of Line N:

(9--2) / (-6-5)

11/-11

The slope of Line N is -1!

Since the slopes of Line N and M are different, they intersect. The answer is Yes, lines M and N intersect because their slopes are different.

If the slopes were the same, Line N and M would NEVER intersect because they are parallel.

Hope this helps

If there are 35 yellow books in the bookcase, then how many green books are in the bookcase
alukav5142 [94]

ANSWER

D. 14

EXPLANATION

The ratio of the books in the book case are:

Red:Yellow:Green=3:5:2

The number of yellow books in the book case is 35.

If 5 corresponds to 35, then 2 green books will correspond to a less number of books,

By proportion, because it is going to be less more will divide.

The number of green books in the book case is

=  \frac{35 \times 2}{5}

= 7 \times 2 = 14
