Answer:
Step-by-step explanation:
4x - 2y = -5
-2y = -4x - 5
y = 2x + 5/2.....slope here is 2
-2x + 3y = -3
3y = 2x - 3
y = 2/3x - 1.....slope here is 2/3
NONE OF THE ABOVE.....they are not the same line....they are not parallel because they dont have the same slope....they are not perpendicular because they do not have negative reciprocal slopes
Answer:
This is exponential

Answer:
c = 9
Step-by-step explanation:
Answer: 10
The arc length of the semicircle is
a+(a+1)+(a+2)+(a+3)+(a+4)=5a+10
As x = 42, this means a+4 is 42/180 of the arc length of the circle, 5a+10.
So,
(42/180)(5a+10)=a+4
42(5a+10)=180(a+4) [multiply both sides by 180]
210a+420=180a+720 [distributive property]
30a+420=720 [subtract 180a from both sides]
30a=300 [subtract 420 from both sides]
a=10 [divide both sides by 30]
