q= -1/2
perpendicular slopes are those that are opposite sign and reciprocal of the original given slope
Answer:
X = -9
Step-by-step explanation:
y = k X for some fixed number constant k.
-5 = k (15)
k = -5/15 = -1/3
So y = (-1/3)X
When y = 3 ---> 3 = (-1/3)X
X = -9
Well, we can really show our work because their is no work to be done. Question 7 is a right angle because it is exactly 90 degrees. So since you now know what a right angle is, you can probably guess Question 8 a would be either 3 o'clock or 9 o'clock. For question 8b , he first one, and acute angle is an angle where it is below 90 degrees. So an example of an acute time is 3:05. An obtuse angle is an angle above 90 degrees. So an obtuse time would be (for example) 3:55. Hope this helped.
