Well just multiply them all. 16×4 is 64. then do 64 times -5. -320.

Well I would say multiply 16*4 to get 64 so unless you want to answer it, the answer is (-5*64) is your simplified equation. ()- is just to separate from the words

* - is multiply symbol. This is much more useful when using variables so your X variable don't get mixed up.

Answer:

x = 10

Step-by-step explanation:

8x + 14 = 6x + 34 (vertically opposite angles are equal)

Rearrange

The equation of the trend line is ŷ = 0.15x - 23.21

<h3>How to determine the average rate of change of the trend line?</h3>

The points are given as:

hr =>808, 768, 655, 684, 637, 619, 613, 609, 563

w => 93, 94, 66, 81, 86, 75, 61, 69, 55.

Using a graphing calculator, we have the following calculation summary:

Sum of X = 5956
Sum of Y = 680
Mean X = 661.7778
Mean Y = 75.5556
Sum of squares (SSX) = 50569.5556
Sum of products (SP) = 7547.1111

The regression equation is represented as:

ŷ = bX + a

Where:

b = SP/SSX

b = 7547.11/50569.56

b = 0.14924

a = MY - bMX

a = 75.56 - (0.15*661.78)

a = -23.20961

This gives

ŷ = 0.14924X - 23.20961

Approximate

ŷ = 0.15x - 23.21

Hence, the equation of the trend line is ŷ = 0.15x - 23.21
