In simplest radical form, what are the solutions to the quadratic equation 6 = x2 – 10x?
Marina86 [1]

we have

6 = x^{2}- 10x

Complete the square. Remember to balance the equation by adding the same constants to each side

x^{2}- 10x+25=6+25

x^{2}- 10x+25=31

Rewrite as perfect squares

(x-5)^{2}=31

(x-5)=(+/-)\sqrt{31}\\ x1=5+\sqrt{31} \\ x2=5-\sqrt{31}

therefore

the answer is

the solutions are

x1=5+\sqrt{31} \\ x2=5-\sqrt{31}

For which mapped relation is the domain {1,2,3}?
Serga [27]

Answer:

C

Step-by-step explanation:

For any given function, all first input values (x-values/coordinates) in the relation are considered as the domain values. While the output values (y-values/coordinates) make up the range of the given function.

The mapped relation that has a domain of {1,2,3}, is the mapped relation that has 1, 2, and 3 on the input side on our left.

Therefore, the mapped relation in option C is the answer.

Pennsylvania has a sales tax of 6%. The city of Philadelphia adds an extra local sales tax of 2%. Both taxes apply to the origin
jonny [76]

Answer:

For the regular tax in Pennsylvania, it would be 12 cents or $0.12. For Philadelphia, it would be 4 cents or $0.04. I got these two amounts by multiplying 2 times 6 or 2 percent, aka 0.06 and 0.02. If you added the two together, you would get, $0.16 or 16 cents. You would then add that to the two dollars and end up with $2.16 or two dollars and sixteen cents. I hope this helps.
