Answer:

-3/4

Step-by-step explanation:

y-y on top in the numerator

x-x on the bottom in the denominator

y= (-2-(-11))= 9

x= ( -4-8)= -12

answer is -9 over 12 or reduced to -3 over 4

The distance between B and C

alina1380 [7]

Answer:

The answer is

<h2> $\sqrt{13} \: \: or \: \: 3.6055 \: \: units$ </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

B ( 3 , 1 ) and C( 6 , 3)

The distance between them is

$|BC| = \sqrt{( {3 - 6})^{2} + ({1 - 3})^{2} } \\ = \sqrt{ ({ - 3})^{2} + ( { - 2})^{2} } \\ = \sqrt{9 + 4}$

We have the final answer as

$\sqrt{13} \: \: or \: \: 3.6055 \: \: units$

Hope this helps you

Sandra's printer can print 5 pages in 2/3 of a minute (40s). Show different ways to determine how many pages her printer can pri

Ne4ueva [31]

Answer:

$7\frac{1}{2}$ pages

Step-by-step explanation:

Method 1: Working with minutes

Let us assume that, Sandra's printer can print x pages in 1 minute.

Then we can write the equation:

$x:1=5:\frac{2}{3}$

We can rewrite the ratios as a fraction.

$\frac{x}{1}=\frac{5}{\frac{2}{3}}$

This simplifies to

$x=\frac{15}{2}$

$x=7\frac{1}{2}$

Method 2: Working with seconds

If 5 pages corresponds to 40 seconds, then we can write: $5:40$

Let y corresponds to 60 seconds (1 minutes).

Then:

$y:60=5:40$

We rewrite as fraction:

$\frac{y}{60}=\frac{5}{40}$

Multiply both sides by:

$y=\frac{5}{40}\times 60$

$y=\frac{300}{40}$

$y=\frac{15}{2}$

$y=7\frac{1}{2}$

If LB = 6 and LN = 2x + 5 , what is x? Show your work.

olga nikolaevna [1]

Answer:

x=3.5

Step-by-step explanation:

MN is divided in half because of MO. BN would equal 6, too. In all, LN should equal 12. So, your equation would be:

2x+5=12

Solve this equation:

2x=12-5

2x=7

x=3.5
