First getting x as a numerator rather than a denominator. Then grouping like terms by moving 5 from the left side to the right. Work below:
Answer:
y = -2x + 21
Step-by-step explanation:
use point intercept form: y = mx + b where m is the slope and b is the y intercept
to find the y intercept, b, plug in values into equation and solve for b
11 = (-2) (5) + b
b = 21
then plug into the equation the slope and intercept!
Answer
given,
opera house ticket = $50
attendance = 4000 persons
now,
opera house ticket = $52
attendance = 3800 person
assuming these are the points on the demand curve
(x, p) = (4000,50) and (x,p) = (3800,52)
using point slope formula




R(x) = x . p




at 

x = 4500

hence at x =4500 the revenue is maximum
for maximum revenue ticket price will be

p = $45
You are correct in selecting choice A as the answer.
You need the middle angles between the two pairs of given congruent sides, so that you can prove the triangles to be congruent through SAS. The vertical angle theorem is used in this case. Alternate interior angles only come from parallel lines, but we dont know if any of the lines are parallel. Even if we did know the lines were paralle, we still wouldn't use the alternate interior angle theorem.
