What value of x makes 1/2 (3x+4) =1/2

Mathematics

Sever21 [200]3 years ago
5 0

Answer:

x = -1

Step-by-step explanation:

1/2 (3x +4 ) = 1/2

1/2 x 3x + 1/2 x 4 = 1/2

1.5 x + 2 = 1/2

1.5x = 1/2 -2

1.5x = -1.5

1.5x /1.5 = -1.5/1.5

x = -1

Check Back

1/2 ( 3 x -1 + 4) =1/2

1/2 ( 1) =1/2

1/2 =1/2

Which equation best represents the data? y = –1.026x2 1016.402x – 162075 y = –1.036x2 1024.771x – 163710 y = 298.214x – 66317.66
yan [13]

Based on the items produced, and the profit yielded from those items, the best model to represent the data is y = -1.026x² + 1,016.402x - 162,075.

<h3>Which model shows the profit and items produced best?</h3><h3 />

You can find this out by testing the models using the items produced (independent or "x" value) to see if the model produces a close enough y value.

Assuming x is 100:

= -1.026x² + 1,016.402x - 162,075

= (-1.026 x 100²) + (1,016.402 x 100) - 162,075

= -$70,694.80

Assuming x is 400:

= -1.026x² + 1,016.402x - 162,075.

= (-1.026 x 400²) + (1,016.402 x 400) - 162,075.

= $80,325.80

These figures are very close to the actual y values given which makes this the best model.

6 = 2(1) + 2(w)

6 = 2 + 2w

Subtract 2 from both sides to isolate 2w.

4 = 2w

Divide 2 on both sides to isolate w.

2 = w
