The answer is C. 0.0 1339
It should be the second one
Answer:
9 sides
Step-by-step explanation:
Given the sum of the interior angles = 1260°, then
180° (n - 2) = 1260 ( divide both sides by 180 )
n - 2 = 7 ( add 2 to both sides ), hence
n = 9
Answer:
78 Words per minute
Step-by-step explanation:
A unit rate is simply comparable to an average. Given this, we can say the following:
Unit_Rate = 3666 Words / 47 minutes
Unit_Rate = 78 Words per minute

The correct statement are the first and the second
=======================================
The first statement:
y = (-2/3) x - (13/3)
slope = -2/3 and passing through (4,-7) because (-2/3) *4 - (13/3) = -7
the slope of the parallel line = -4/6 = -2/3
============================================================
The second statement
y = (-7/2) x - (5/2)
slope = -7/2 and passing through (-3,8) because (-7/2) *-3 - (5/2) = 8
the slope of the perpendicular line = 2/7
the multiplication of the two slopes = -7/2 * 2/7 = -1
============================================================
The third is false
because the lines are parallel not perpendicular
the fourth is false
because the lines are perpendicular not parallel
