Solve for x. Write the smaller solution first, and the larger solution second. (x-10)^2-1=0
ikadub [295]

Answer:

x_1 = 9 and x_2 = 11.

Step-by-step explanation:

Start by adding 1 to both sides of this equation.

(x - 10)^{2} = 1.

The square of what number or numbers will lead to the number "1"? It turns out that not only 1^{2} = 1, but (-1)^{2}= 1 as well. In other words, the value (x - 10) can be either 1 or -1. Either way, the equation is still going to hold. That's the reason why there are two solutions to this equation.

Consider the case when x - 10 = 1. Add 10 to both sides of the equation. x = 11.

Now, consider the case when x - 10 = -1. Again, add 10 to both sides of the equation, x = 9.

Order the two solutions in an increasing order:

  • x_1 = 9,
  • x_2 = 11.

Find the indicated length.<br> Line WX bisects YZ at point W. Find YZ if WZ=9 5/8
Montano1993 [528]

Given :

Line WX bisects YZ at point W.

WZ=9\dfrac{5}{8}=\dfrac{77}{5} .

To Find :

The length of YZ .

Solution :

Since , the point W bisect YZ .

So , it cuts YZ into two equal parts i.e YW and WZ .

Therefore , YW = WZ

Also , YZ = YW+WZ = 2WZ

YZ = 2\times \dfrac{77}{5}\\\\YZ=\dfrac{154}{5}\\\\YZ=30\dfrac{4}{5}

Hence , this is the required solution .

At an annual salary of $55,000 per year, what is the amount of semimonthly paychecks?
Amiraneli [1.4K]
Semi monthly means 2 times per month
assume that pay is at beginning and middle of month (doesn't matter, but  makes it easier for me)

so 12 months
2 times per month
12 times 2=24
divide 55000 by number of months
55,000/24=2291.67

so the amount per paycheck, assuming equally distributed amounts throughout the paychecks, is $2291.67
