You are given a table in which each row represents the coordinates of points.  For example, in the first line, we have x=-7 and y=5.  Work through the four given equations, one at a time, subbing -7 for x and 5 for y; is the equation still true?  If yes, then you have found the correct answer.  B is the exception; I'd suggest you check out equations A, C and D first, before focusing on B.

Example:  D:  (5)-5 = 2((-7) + 7) leads to 0 = 0.  Is that true?  If so, D is likely the correct answer.

A triangular city lot bounded by three streets has a length of 300 feet on one street, 250 feet on the second, and 420 feet on t
Butoxors [25]

Consider using the Law of Cosines, because the lengths of three sides are given and the largest angle is the one to be approximated. This angle will be opposite the longest side, that is, opposite the 420-foot side.

420^2 = 250^2 + 300^2 - 2(250)(300)cos A.

Then: 176400 = 62500 + 810000 - 150000cos A.

Solving for cos A, we get:

150000cos A = 176400-62500-810000, or -696100

Then:

-696100

cos A = ------------------- = - 4.64. This is not possible, as the range of the cosine

150000 function is [-1,1].

You begin the week with 20 units of milk. You purchase 40 units. Your ending inventory for the week is 30 units. How many units
Musya8 [376]

Answer:

30 units.  

Step-by-step explanation:

Let x be number of milk units sold.

It has been given that You begin the week with 20 units of milk. You purchase 40 units. Therefore, total units of milk will be 20+40=60 units.

It has been given that your ending inventory for the week is 30 units, which means after selling x units from 60 units you are left with 30 units.

We can set this information in an equation as:

60-x=30

-x=30-60

-x=-30

x=30

Therefore, you have sold 30 units.

HELP ME PLEASE !!!!!!!!!
Kay [80]

Answer: 33 333,33 per month or 400 000 per year

Step-by-step explanation:

You need 48 000 + 0.035X = 62 000

So ( 62 000 - 48 000 ) / 0.035 = X

Then you can divide X per 12 (months in a year)

And you have your answer per month .

So 33 333,33 total sale per month to have at least as high as the average pay
