The sllope-intercept form:

<em>add 12 to both sides</em>
<em>divide both sides by 6</em>

The formula states that:
Faces + Vertices - Edges = 2
So 21 + V - 49 = 2 => V = 2+49-21 = 30
Answer A!
Yes. 2 squared is irrational number because no two of the same numbers multiplied equals 2. Not including decimals either.
So if she got them at 30% off that means
$63 = 70%
divide both sides by 70 to get 1%
$0.90 = 1%
multiply by 100 to get full price
$90 = 100%
original price was $90
Answer:
25, 21, 13, 9
Step-by-step explanation:
All you do here is plug in the X from the table to the X in the equation so,
y=29 - 4 x 1 = 25
y=29 - 4 x 2 = 21
y=29 - 4 x 4 = 13
y=29 - 4 x 5 = 9
