Y=4x−9<br> Complete the missing value in the solution to the equation
weeeeeb [17]

Answer:

<h2>The missing value is 3, and the coordinates are (3,3).</h2>

Step-by-step explanation:

The complete question is

y=4x-9

Complete the missing value in the solution to the equation. (3, ? )

By given, we know that x=3, because coordinates are written like (x,y).

Then, we replace the given coordinate to find y.

y=4x-9\\y=4(3)-9\\y=12-9\\y=3

Therefore, the missing value is 3, and the coordinates are (3,3).

How to solve this using trigonometry?
Leya [2.2K]
Using SOHCAHTOA and Kenui's height and angle of depression (which is the downward angle from the horizontal ) the answer should be:  

because its the Adjacent and Opposite sides use Tan;  
Tan(6.8) = o/a
tan(6.8) = Distance / 219
tan(6.8)(219 = Distance 
26.114 m 

But because the angle of depression is the downward angle from the horizontal the answer may be Tan(83.2)(219) = 1836.589
the 83.2 coming from 90 degrees - 6.8 degrees 

either way i"m still unsure because I don't see a need for the two angles or Mias involvement, sorry if I'm wrong

Ms. Lunette has 18 students in her class. She wants to send 3 of these students to pick up books for the class.
tigry1 [53]

The number of possible combinations is given by

... C(18, 3) = 18!/(3!(18-3)!) = 18·17·16/(3·2·1) = 816 . . . . possible combinations

_____

There are 18 ways to choose the first one; 17 ways to choose the second one, and 16 ways to choose the 3rd one. The same 3 students can be chosen in any of 3! = 6 different orders, so the product 18·17·16 must be divided by 6 to get the number of possible combinations in which order doesn't matter.
