Answer:
intercept 
line 
Step-by-step explanation:
Let 
is the required line.
<u>Slope of perpendicular lines :</u> If 
and 
be slope of two perpendicular lines. Them 
is perpendicular to 
the slope of is 
Hence eqn is 
This equation passes through 
so the line is
<u>y-intercept :</u>
Substitute 
I don’t really get what you’re asking here but a system of 2 parallel lines has no solution, and a system of 2 parallel lines is called inconsistent.
Answer:
)x + 5)(x - 5)
Step-by-step explanation:
x² - 25 ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b), thus
x² - 25 = x² - 5² = (x + 5)(x - 5)
Answer:
c.They rank-order the units of analysis in terms of specific variables
Step-by-step explanation:
An index is a way of compiling one score from a variety of questions or statement that represents a belief, feeling or attitude.
Scales on the other hand measure levels of intensity at a variable level like how much a person agrees or disagrees with a particular statement.
The one thing common to both indexes and scales is that
They rank-order the units of analysis in terms of specific variables.
