Choose the model that represents the function
kirill [66]

Answer:

OPTION D

Step-by-step explanation:

We have to determine which option determines the function given above.

To determine the function, just substitute the values and compare LHS and RHS.

we have $ f(4) = 18 $

$ f(-2) = -12 $

$ f(0) = -2 $

$ f(-3) = -17 $

Here, $ x $ is the domain and $ f(x) $ is the co-doamin.

Therefore, $ x = \{4, -2, 0, -3\} $

Now, OPTION A: $ f(x) =  2x - 5 $

Substitute x = 4. We get f(x) = 3 $ \ne $ 18.

So, OPTION A is rejected.

Similarly, OPTION B: $ f(x) = 5x + 2 $

Substitute x = 4. We get f(4) = 22 $ \ne $18.

It is rejected as well.

Now, for OPTION C: $ f(x) = \frac{x}{2} - 5 $

Substitute x = 4. We get f(4) = -3 $ \ne $ 18.

So, OPTION C is also rejected.

OPTION D: $ f(x) =  5x - 2 $

Substitute x = 4. We get f(4) = 18.

Substitute the remaining points in domain as well. We notice that it exactly matches the given function. So, OPTION D is the answer.

Find the value of X. The diagram is not to scale. Lines F and G are parallel.
sergejj [24]

Step-by-step explanation:

2 × (First Angle + Second Angle) = 360°

5x + 9x + 26 = 360°/2

14x + 26 = 180°

14x = 180 - 26

14x = 154

x = 154/14

x = 11°

The answer is B.

-3+4u=-31 solve for u
solniwko [45]

Answer:

u = -7

Step-by-step explanation:

-3+4u=-31

Add 3 to each side

-3+3 +4u = -31+3

4u = -28

Divide each side by 4

4u/4 = -28/4

u = -7
