Lerok [7]

Answer:

7y-10

Step-by-step explanation:

9y-\frac{1}{2}\left(4y+20\right)

To simplify this expression, first use the distributive property to distribute \frac{1}{2}.

9y-\frac{1}{2}(4y)+-\frac{1}{2}(20)

Simplify.

9y+-2y+-10

Combine like terms, 9y and -2y.

7y-10

The simplification of 9y-\frac{1}{2}(4y+20) is 7y-10.

I hope this helps ^^

Good luck

Answer:

<u>First blank:</u>  2. Extrapolation

<u>Second blank:</u> 2. 69

Step-by-step explanation:

Extrapolation should be used because the point (x, y) is further than the points included in the table, that is, the x-coordinate will be greater than 12 when y = $0

Replacing y = 0 into the equation, we get:

0 = -115.9x + 8,007.30

115.9x = 8,007.30

x = 8,007.30/115.9

x = 69
