Answer:

x=-1/2

Step-by-step explanation:

2(4x + 2) = 4x – 12(x - 1)

8x+4=4x-12x+12

8x+4=-8x+12

-4 -4

8x=-8x-8

+8x +8x

16x=-8

16x/16=-8/16

x=-1/2

6 children need to share 5 breakfast bars Divide bars into correct numbers of equal parts then tell the fraction each kid will g

tigry1 [53]

-- Carefully cut <em>each bar into 6 equal pieces</em>.
   There are (5 x 6) = 30 pieces all together.
   Each piece is 1/6 of a bar.

-- Each child gets 5 of the pieces.
   That's the same as <em>5/6 of a whole bar</em>.
   (6 children) x (5 pieces) = 30 pieces. It works out. yay !

If tanA+sinA=m and tanA-sinA=n.prove that m^2-n^2=4√mn

mash [69]

Let $a=\tan A$ and $b=\sin A$ . Then

$m^2-n^2=(a+b)^2-(a-b)^2=(a^2+2ab+b^2)-(a^2-2ab+b^2)=4ab$

$\implies m^2-n^2=4\tan A\sin A$

and

$mn=(a+b)(a-b)=a^2-b^2$

$\implies4\sqrt{mn}=4\sqrt{\tan^2A-\sin^2A}$

The expression under the square root can be rewritten as

$\tan^2A-\sin^2A=\dfrac{\sin^2A}{\cos^2A}-\sin^2A=\sin^2A\left(\dfrac1{\cos^2A}-1\right)=\sin^2A(\sec^2A-1)$

Recall that

$\sin^2A+\cos^2A=1\implies\tan^2A+1=\sec^2A$

so that

$\tan^2A-\sin^2A=\sin^2A\tan^2A$

and assuming $\sin A>0$ and $\tan A>0$ , we end up with

$4\sqrt{\tan^2A-\sin^2A}=4\tan A\sin A$

so that

$m^2-n^2=4\sqrt{mn}$

as required.

The data reflects the number of hours an employee spends working a checkout line (x), paired with the number of customers served

Whitepunk [10]

The slope of the line can be interpreted that with each additional hour, nearly 18 customers are served; option B

<h3>What is the slope of a line?</h3>

The slope of a line is the ratio of climb to that of run

Slope = change in y/change in x

The given graph is a graph of the number of hours an employee spends working a checkout line (x), against the number of customers served (y).

The slope of the graph can be written as follows:

Slope = change in the number of customers served/change in the number of hours an employee spends working

Therefore, the slope of the line can be interpreted that with each additional hour, nearly 18 customers are served.

In conclusion, slope of a line is ratio of change in y to change in x.
