Answer:

<h2>x = 40</h2>

Step-by-step explanation:

fx=2x-50    

Find x when fx=30

plugin values into the equation

30 = 2x - 50

combine similar term:

30 + 50 = 2x

simplify:

80 = 2x

x = 80/2

x = 40

proof: fx = 30

f(x) = 2x - 50

     = 2(40) - 50

     = 80 - 50

     = 30

30  = 30  ok

Answer:

∠ XZY ≈ 23.6°

Step-by-step explanation:

Using the sine ratio in the right triangle, that is

sinXZY = \frac{opposite}{hypotenuse} = \frac{XY}{YZ} = \frac{6}{15} , then

∠ XZY = sin^{-1} (\frac{6}{15} ) ≈ 23.6° ( to 1 dec. place )

Answer:

The first blank is: 26

The second blank is: 17

The third blank is: 31 - n

Step-by-step explanation:

So basically each row should add up to 31.  So for every number they give you (doesn't matter which color ball), you need to subtract it from 31.

That's why for the first blank, 31 - 5 is 26

second blank, 31 - 14 is 17

and so on....

so the resulting function would be 31 - n

n being a random number that is given to you
