The number is: "2 " .

Explanation:

Write the expression; which is an equation, as follows:

" 4x − 12 = 2(-x) " ; in which "x" represents "the number for which we shall solve" .

Note:

If the "number" = "x" ; the "opposite of the number" = " -x " ;

Rewrite as: " 4x − 12 = -2x " ;

→ Add "12" ; & add "2x" ; to EACH SIDE of the equation:

4x − 12 + 12 + 2x = -2x + 12 + 2x ;

to get: 6x = 12 ;

Now, divide each side of the equation by "6" ;
to isolate "x" on one side of the equation; & to solve for "x" ;

6x / 6 = 12 / 6 ;

to get: x = 2 .

The number is: "2 " .

Let us check our answer, by plugging in "2" for "x" in our original equation:

→ " 4x − 12 = 2(-x) " ;

Let us plug in "2" for "x" ; to see if the equation holds true; that is; if both side of the equation are equal; when "x = 2" ;

→ " 4(2) − 12 = ? 2(-2) ??

→ 8 − 12 = ? -4 ? ;

→ -4 = ? -4 ?? Yes!

Answer from: Quest

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data. the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center. with the histogram, we cannot find any of these.

If p(x) is the total value of the production when there are x workers in a plant, then the average productivity of the workforce at the plant is a(x) = p(x) x . (a) find a'(x). a'(x) = xp'(x) − p(x) x a'(x) = xp'(x) − p(x) x2 a'(x) = p'(x) − p(x) x a'(x) = xp'(x) − p'(x) x2 a'(x) = p'(x) − xp(x) x2 why does the company want to hire more workers if a'(x) > 0? a'(x) > 0 ⇒ a(x) is ; that is, the average productivity as the size of the workforce increases. (b) if p'(x) is greater than the average productivity, which of the following must be true? p'(x) − xp(x) > 0 p'(x) − xp(x) < 0 xp'(x) − p'(x) > 0 xp'(x) − p(x) < 0 xp'(x) − p(x) > 0
