y=10x+175
y=.05x+220

Jessica and martha each have a bag of cookies with unequal quantities. they have 30 cookies total between the two of them. each of them ate 6 cookies from their bag. the product of the number of cookies left in each bag is not more than 80. how many more cookies will jessica have martha? if x represents the number of cookies jessica started with, complete the statements below. the inequality that describes the relationship between the number of cookies each one of them has is x^2 - x +224 > = 0.jessica has at least cookies more than martha.

Write the expression as a single natural logarithm. 2 in a - 4 in y

Which inequality statement describes the two numbers on a number line? "? 7 and a number 5 units to the right of ? 7"
