Ask a question the absolute value of the sum of two different integers with the same sign is eight. pat says there are three pairs of integers that match this description. do you agree? ?

Both integers must be positive or negative. You cannot have a positive integer and a negative integer. Also, you cannot have zero. You can't use 4 and 4 or -4 and -4 because then you'd have the same integer.

|1 + 7| = 8

|2 + 6| = 8

|3 + 5| = 8

|-1 + (-7)| = 8

|-2 + (-6)| = 8

|-3 + (-5)| = 8

There are 6 pairs of numbers that match the description. I do not agree with Pat.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

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.
