Answer:

x=-3.5, x=13.5

Step-by-step explanation:

-10x-47=-x^2+1

<u>switch sides</u>

-x^2+1=-10x-47

<u>add 47 to both sides</u>

-x^2+1+47=-10x-47+47

<u>simplify</u>

x^2+48=-10x

<u>add 10x to both sides</u>

-x^2+48+10x=-10x+10x

<u>simplify</u>

-x^2+10x+48=0

<u>solve with the quadratic formula</u>

a=-1, b=10, c=48:

x=-10±√10²-4(-1)48/ 2(-1)

(you can plug this into a calculator or use PEMDAS to solve)

(solve it twice: use - once, and + the second time)

<u>answer:</u>

x=-3.5, x=13.5

<u></u>

mojhsa [17]

Answer:

The answer is "bulb, expands, and glass ".

Step-by-step explanation:

The bulb thermometer is the common glass temperature sensor for which you might be grown up. This thermometer is filled with a liquid, typically mercury. Bulb thermometers work on the simple premise that it volume of the liquid varies in proportion to its volume.

It is a glass tube that is pre full with a fluid such as a hydrogen or liquor and is sealed at both sides. The fluid in the glass tube rises as the mercury inside the thermometer's bulb increases. When the temperature gauge is warm, the liquid inside flows up in the tube.
