The inequality that will determine the number of items that need to be sold to make a profit is
To make a profit, a company's revenue must be greater
than its operating costs. The company's revenue is
modeled by the expression 7 5x - 100
where x represents the number of items sold. The
company's operation costs are modeled by the
expression 79 86 + 5 8x. How many items does the
company need to sell to make a profit?
The solution to the inequality is
The company must sell at least
a profit
items to make

is there answer choices?

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
