List the steps that should be used to solve the equation f(x) = g(x) by graphing when f(x) = (1/2)² - 3 and g(x) = 3x + 5?

jolli1 [7]

value of x is: $x=\frac{-31}{12}$

Step-by-step explanation:

We need to solve the equation f(x)=g(x)

where $f(x)=(\frac{1}{2})^2-3$

and $g(x) = 3x + 5$

Solving to find f(x)=g(x)

Putting values of f(x) and g(x)

$f(x)=g(x)\\(\frac{1}{2})^2-3=3x + 5\\\frac{1}{4}-3=3x + 5\\Subtarct\,\,5\,\,on\,\,both\,\,sides:\\\frac{1}{4}-3-5=3x + 5-5\\\frac{1}{4}-8=3x\\Taking\,\,LCm\,\,on\,\,left\,\,side\\\frac{1-8*4}{4}=3x\\\frac{-31}{4}=3x\\Divide\,\,both\,\,sides\,\,by\,\,3\\x=\frac{-31}{4*3}\\x=\frac{-31}{12}$

So, value of x is: $x=\frac{-31}{12}$

The graph will be a straight line x= -2.58 or x = -31/12

The area of a square tile is 49 square inches. Write the length of one side of the square time as a square root and standard fro

aleksandr82 [10.1K]

A square area=legnth times width
but for a square, legnth=width so
area=legnth^2

are=49
49=legnth^2

square root of both sides
7=legnth
the answer is 7

Can somebody please help me .

Lyrx [107]

Answer:

Both of theses are irrational.

Step-by-step explanation:

The reason is because when you try to find out how to get the square root of 2 you get a whole bunch of numbers, and the same thing happens when you try to find the square root of 8. in turn both of these numbers are irrational.
