<span>What is the slope of a line segment with endpoints at (-1, 1) and (1, 5)
the slope would be 6/2 rise/run
</span>
Y=3x-2 is parallel to line a(have the same slope)
y=-1/3x-10 is perpendicular
y=1/3x+1 is not parallel nor perpindicular
Answer:
-1680
Step-by-step explanation:
Above would be positive.
Below would be negative.
You have 1680 below, so the answer as a signed number for the elevation would be -1680.
Okay so a right angle is 90 degrees so we take 90 degrees and subtract 63 from it
90-63=17 degrees
so X=17
Then in order to find Y, we have to realize these are alternate interior angles so they equal the same
your equation is 3y=63
you divide y by 3 to isolate it and
Y= 21
Hope this helps:)
Answer:
a=6
b= -15
Step-by-step explanation:
third term --> n=3
a(3)^2 + b(3) =9
9a+3b=9
3(3a +b)=9
3a +b=9/3=3
3a + b=3 ------eqn1
sixth term n=6
a(6)^2 +6b =126
36a +6b=126
6(6a+b)=126
6a + b =126/6=21
6a + b=21----------eqn 2
eqn2 - eqn 1
(6a-3a) +(b-b) =21-3
3a=18
a=18/3=6
sub a= 6 into eqn2
6(6)+b=21
36 +b =21
b=21-36= -15
