Answer:

2.89

Step-by-step explanation:

Note the equal sign, what you do to one side of the equation, you do to the other. To solve, do the opposite of PEMDAS. Isolate the variable, z.

First, subtract 12 from both sides:

25 = 4.5z + 12

25 (-12) = 4.5z + 12 (-12)

25 - 12 = 4.5z

13 = 4.5z

Isolate the variable, z. Divide 4.5 from both sides:

(13)/4.5 = (4.5z)/4.5

z = 13/4.5

z = ~2.89 (rounded).

2.89 is your answer.

Answer: z = 2.8

Step-by-step explanation:

Subtract 12 from both sides.

25-12=4.5z

Simplify 25-12 to 13

13=4.5z13=4.5z

divide both sides by 4.5

13 ÷ ​4.5 = z

Simplify

z = 2.888889

z = 2.8

Hope this helps!!! Good luck!!! ;)

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

The table on the items produced by this company and the profits derived from these goods shows that the best model is y = -1.026x² + 1,016.402x - 162,075.

<h3>Which model best represents the data?</h3><h3 />

Find out the best model by testing all models assuming a given value of x. The model that gives a y value closest to the actual value is the best model.

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

Second model:

= -1.036x² + 1024.771x - 163710

= (-1.036 x 100²) + 1024.771 x 100 - 163710

= -$71,593

Third model:

=  298.214x - 66317.667

= 298.214 x 100 - 66317.667

= -$36,496.27

Fourth model:

= 196.2x - 18710

= 196.2 x 100 - 18,710

= $910

The best model is therefore the first model which shows the closest value to the actual y value of -$70,500 when x is 100.

Please help me with this question
Vlad1618 [11]

Answer:

Step-by-step explanation:

a1 = 3;

a2 = 2(a1 - 2 ) = 2(3-2) = 2

a2 = 2

a3 = 2(a2-2) = 2(2-2) = 0

a3=0

a4 = 2(a3-2) = 2(0-2) = -4

a4 = -4

a5 = 2(a4 - 2) = 2(-4-2) = -12

a5 = -12
