Perpendicular is when the slopes multiply to negative 1
remember
the slope of the line in form
ax+by=c is -a/b
find slopes
2x+ky=6
slope is -2/k
6x-4y=12
slope is -6/-4=3/2
so
-2/k times 3/2=-1
solve for k
-6/(2k)=-1
times both sides by 2k
-6=-2k
divide by -1
3=k
k has to be 3
Answer:
<h2> 8in</h2>
Step-by-step explanation:
the given formula in the question is not correct
here is the correct formula
S. A. =2πr^2 +2πrh
given that S.A=207.24
radius r= 3in
207.24=2*3.142*(3)^2 +2*3.142*(3)h
207.24=56.556 +18.852h
207.24-56.556=18.852h
150.684=18.852h
h=150.684/18.852
h=7.99
Approximately the height is 8in
Answer:
-84
Step-by-step explanation:
Answer:
(-2, -5)
Step-by-step explanation:
in a rectangle there will be 4 different numbers. Each number will have 2 spots. 2 numbers will have 2 x spots, and 2 numbers will have 2 y spots. we notice that our numbers are -2, -5, 3, and 4.
we see that -2 and 3 are our x values, and -5 and 4 are our y values.
-2 and -5 are the 2 numbers that have not been repeated, so the last corner's coordinates are (-2,-5)
