Look at the two equations:
-3x + 6 = 21
-3x+6 < 21
Which statement best describes the process used to solve the equations?

1. In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality.

2. In both cases, divide by -3 on both sides, but reverse the inequality sign when doing that for the inequality.

3. The process is exactly the same for solving the equation and solving the inequality.

4. The process for solving the equation is entirely different from solving the inequality.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
