The required equation is y = -9
Step-by-step explanation:
Step 1 :
Given the line l is perpendicular to the y axis
The equation of the y axis is x = 0
So any line perpendicular to the y axis will have equation as y = k , where k is a constant value for any value of x
Step 2 :
Its given that the line is passing through the point (0.-9). Here the y co ordinate is -9. Hence the perpendicular line has a constant y co ordinate of y = -9 for any value of x
So the required equation is y = -9
Step 3 :
Answer :
The required equation is y = -9
1) property of distribution: 30 = -30n - 30
2) inverse property of addition: 60 = -30n
3) inverse property of multiplication: -2 = n
step 2: subtract 30 from both sides
step 3: divide -30 from both sides
Y = 300e^(-Bt)
plug in y = 75 and t = 2
75 = 300e^(-2B)
75/300 = e^(-2B)
ln(75/300) = -2B
B = -ln(75/300) / 2
so B = approx 0.693300 = A(e^0) = A

The answer is -1.
You do -2- -4 and get 2.
Then do -2-0 and get -2.
The last step is to do 2 divide -2 and you get -1.
They give you: <RSP = 90 degrees
If you look in the diagram, <RSP is vertical to <UPW and vertical angles have the same measure. <RSP = <UPW
So the correct answer is A.
