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

Identify the first 4 terms in the geometric sequence given by the explicit formula ƒ(n) = 4 × 2(n – 1).

saw5 [17]

Step-by-step explanation:

1st term =4×2(1-1)=0

2nd term=4×2(2-1)=8

3rd term=4×2(3-1)=16

4th term=4×2(4-1)=24

The measures of an angle and its supplement differ by 40°. What are the measures of the angles? Hint: An angle and its supplemen

bogdanovich [222]

Let the two numbers be x and x + 40, then
x + x + 40 = 180
2x = 180 - 40 = 140
x = 140/2 = 70
Therefore, the measures of the two angles are 70° and 70 + 40 = 110°

If 2X +1= 27,032 is true then 2x+3= ?

maxonik [38]

2x+1=27032
2x=27031
x=13515.5

2x+3
=2(13515.5)+3
=27034
