(3)
Parallel lines have equal slopes
the equation of a line in sloipe- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 
x + 5 ⇒ m =
y = 4x + 5 ⇒ m = 4
y = - 4x + 5 ⇒ m = - 4
y = - 4x - 9 ⇒ m = - 4
the 3rd and 4th options have equal slopes and are parallel
(4)
given a line with slope m then the slope of a line perpendicular to it is
= - 
y = 
x + 4 ⇒ m =
y = - x + 5 ⇒ m = -
y = x + 3 ⇒ m =
y = 6x + 3 ⇒ m = 6
note that a slope of m = 6 , has a perpendicular slope of
= -
the 2nd and 4th lines are perpendicular
Answer: 27 rows contain 25 vines.
Step-by-step explanation:
Let x represent the number of rows that contain 20 vines.
Let y represent the number of rows that contain 25 vines.
Sarah plants 760 vines in rows containing either 20 vines or 25 vines. This means that
20x + 25y = 760- - - - - - - - - - -1
There are 3 times as many rows containing 25 vines as there are rows containing 20 vines. This means that
y = 3x
Substituting y = 3x into equation 1, it becomes
20x + 25 × 3x = 760
20x + 75x = 760
95x = 760
x = 760/95
x = 9
y = 3x = 3 × 9
y = 27
Answer:
The digit 5 is 50 in this case because it is in the tenths place. Hopefully that helps! :)
3^15/3^3 = 3^12 or 531441
