Manuela solved the equation 3−2|0.5x+1.5|=2 for one solution. Her work is shown below. 3−2|0.5x+1.5|=2 −2|0.5x+1.5|=−1 |0.5x+1.5
forsale [732]

Answer:

x=-4

Step-by-step explanation:

The given equation is

3-2|0.5x+1.5|=2

Subtract 3 from both sides.

3-2|0.5x+1.5|-3=2-3

-2|0.5x+1.5|=-1

Divide both sides by -2.

\dfrac{-2|0.5x+1.5|}{-2}=\dfrac{-1}{-2}

|0.5x+1.5|=0.5

If |x|=a, then x=a or x=-a.

0.5x+1.5=\pm 0.5

Case 1: 0.5x+1.5=0.5

Subtract 1.5 from both sides.

0.5x=0.5-1.5

0.5x=-1

Divide both sides by 0.5.

x=-2

Case 2: 0.5x+1.5=-0.5

Subtract 1.5 from both sides.

0.5x=-0.5-1.5

0.5x=-2

Divide both sides by 0.5.

x=-4

Therefore, one solution is x=-2 and other solution is x=-4.

Find the slope of the line through each pair of points(-13,-18),(0.-17)
Jet001 [13]
The slope formula is

=2−1/2−1

For the first one it would be:

-17-(-18)/0-(-13)=1/13

m=1/13



Second one:

m=−16−−9/−17−−18= -7/1

m=-7

For the there one:

Slope =−12−−13/6−−1=1/7

m=1/7





I hope it was helpful. If you have any questions let me know.

from 1960 to 1970, the consumer price index increased from 29.6 to 38.8 if a dozen tangerines cost $0.31 in 1960 and the price o
Nitella [24]

The percent increase in the price index from 1960 to 1970 is:

% increase in price index = (38.8 – 29.6) * 100% / 29.6

% increase in price index = 31.08%

Therefore the price of a dozen tangerines in 1970 (X) is:

31.08 = (X - $0.31) * 100 / $0.31

<span>X = $0.41</span>
