Answer:

y = 1/2 x - 4

Step-by-step explanation:

slope of perpendicular line is 1/2

y +3 = 1/2 (x -2)

y + 3 = 1/2x - 1

y = 1/2x - 4

The graph of the step function g(x) = –⌊x⌋ + 3 is shown. What is the domain of g(x)? {x| x is a real number} {x| x is an integer
allsm [11]

Answer:

Option A is correct.

The domain of the g(x) is {x | x is a real number}

Step-by-step explanation:

The graph of the step function: g(x)=-\left \lfloor x \right \rfloor +3


Floor function is defined as the function that gives the highest integer less than or equal to x.

The graph of function: g(x)=-\left \lfloor x \right \rfloor +3  where x is the independent variable as shown below;

Domain of any function is the complete set of possible values of the independent variable

Therefore, the domain of the function g(x) is the set of all real numbers or we can represent this as  {x | x is a real number}.

What is the value of x?<br><br><br><br> Enter your answer in the box.<br><br> °
Gnom [1K]

Answer:

The answer to your question is:  111°

Step-by-step explanation:

The sum of the interior angles of a polygon is (n - 2) 180°

This polygon has 7 sides

Then n = 7

Process

  120 + 158 + 126 + 125 + 121 + 139 + x = (7 - 2)180

  120 + 158 + 126 + 125 + 121 + 139 + x = 5(180)

  789 + x = 900

  x = 900 -789

  x = 111°

State the excluded values for each? 70v^2/100v
sleet_krkn [62]
Ok so any number tat makes the denomenator 0 or makes the inside of a square root negative is restricted
we only have a denomenaor so
100v=0
v=0
therefor 0 is the excluded value since 0/0 doesn't make sense
