Answer:
slope = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 
x - 2 ← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= - 3
3 baseball cards = $160
first card + (second card + third card) = $160
first card = second card + third card
$160 ÷ 2 = $80
thus the first card was $80
If there are 1,400,000 drops in 25 gallons:
1 drop = 25 gallons : 1,400,000 = 0.0000178 gallons
It is 0.00178 % of a gallon.
Odd numbers are represented as 2n+1 where 2 is a natural number ( negative and possitive whole numbers)
consecutive odd numbers are 2 away from each other so 3 consecutive odd numbers would be
(2n+1),(2n+1+2),(2n+1+2+2)
the all add to -15 so they must all be negative
2n+1+2n+1+2+2n+1+2+2=-15
add like terms
6n+9=-15
subtract 9 from both sides
6n=-24
divide both sides by 6
n=-4
subsitute
first number=2n+1=2(-4)+1=-8+1=-7
second number=2n+1+2=2(-4)+3=-8+3=-5
third number=2n+1+2+2=-8+5=-3
the numbers are -7,-5, -3
the answe ris B
