Which sentence correctly compares the two points shown on the number line? -1 &gt; 0.25 , -1 &lt; -0.25, -0.25 &lt; -1
BartSMP [9]

Answer:

-1<-0.25

With -1>0.25 you have a negative(-1) and a positive(0.25) the negative will always be less than the positive proving the equation wrong

Moving onto -1<-0.25 this one is a little trickier because they both have a negative so this is where you look at the number line and see which number is closer to 0 and whichever number is is greater meaning this is the correct answer.

What is the slope of the line through (-9,6) and (-6,-9)?<br> Your answer must be exact.
iogann1982 [59]
The formula for slope is:

m=\frac{y_{2}-y_{1}}{x_{2}-{x_{1}}

So just plug in the values:

m=\frac{-9-6}{-6+9}=\frac{-15}{3}=-5

So m=-5!

How to find the scale factor of two triangles
BabaBlast [244]

Answer:

Here's how to do it.  

Step-by-step explanation:

The two triangles must be similar, that is, corresponding angles must be equal, as in the diagram below.

1. Find a corresponding pair of sides

Assume that ∆ABC is the original and ∆DEF is its scaled image.

Then, AB and DE are corresponding sides, with lengths of 8 and 12 units , respectively.

2. Set up a ratio

Ratio = side length in image/side length in original = 12/8

3. Simplify the ratio

The simplified ratio is the scale factor (SF).

SF = 12/8 = 3/2 = 1.5

The scale factor is 1.5.
