To make the expression 4x-2 + (2x + 4) equivalent to 2(6x + 7), what must be the value in the box?
podryga [215]

4x - 2 + (2x + 4) = 2(6x + 7) \\

4x - 2 + 2x + 4 = 12x + 14

Simplification

6x + 2 = 12x + 14

Subtract sides 2

6x + 2 - 2 = 12x + 14 - 2

Simplification

6x = 12x + 12

Subtract sides -12x

6x - 12x = 12x - 12x + 12

Simplification

- 6x = 12

Divided sides by -6

\frac{ - 6}{ - 6}x =  \frac{12}{ - 6} \\

x =  - 2

It is must be in the box buddy.

And we're done...♥️♥️♥️♥️♥️

kumpel [21]

Answer:

<u>Poloma’s equation has a positive slope, but the scatter-plot has a negative correlation.</u>

Step-by-step explanation:

The scatter-plot is as shown in the attached figure.

As shown in the figure, the scatter-plot has a negative correlation.

And the equation of Poloma is y = 5/6x - 31/6

Where the slope of the line = 5/6 and y-intercept = -31/6

According to the previous information, the true statement is:

Poloma’s equation has a positive slope, but the scatter-plot has a negative correlation.
