Put all the angles = 180 (for a triangle's sum is 180 degrees)

x - 4 + 100 + 3x = 180

Add numbers (& common variables) together

3x + x + 100 - 4 = 180

4x + 96 = 180

isolate the x, subtract 96 from both sides

4x + 96 (-96) = 180 (-96)

4x = 180 - 96

4x = 84

isolate the x, divide 4 from both sides

4x = 84

4x/4 = 84/4

x = 84/4

x = 21°

hope this helps

The owner of a luxury motor yacht that sails among the 4000 Greek islands charges $540 per person per day if exactly 20 people s
lora16 [44]

Answer:

Step-by-step explanation:

Charges up to 20 passengers = $540 per person per day

Total charges = 540 × 20 = $10800

If x passengers above 20 sign up for the cruise then total number of passengers = (20 + x)

Total revenue = $(20+x)

But each fare is reduced by $7 for additional passenger above 20 then revenue generated R(x) = 540(20+x) - 7x

R(x) = 10800 + 540x - 7x

R(x) = 10800 + 533x

a). Revenue per day realized R = 10800 + 533x

b). R(48) = 10800 + 48×533

              = $36,384

C). R(78) = 10800 + 78×543

              = $53,154

y- y1 = m (x - x1 )

m = 4

x1 = -2

y1 = 5

Math Help Please....
rodikova [14]
Let's go through the answer choices one by one:

A. False. The line segment contains more than just the endpoints

B. False. There are points in this description that extend beyond the endpoints. If this was a line instead of a segment, then choice B would be the answer

C. True. This is the answer. Though your teacher should have added "collinear" to the sentence to make it clear that the points are between M and N, and also collinear to M and N. All of these points form the line segment MN

D. False. That would be the perpendicular bisector of MN

----------------------------------------------------------------------------------------------------

So once again, the final answer is choice C
