Dena is trying to solve this problem: A store has a sale where every item has a sale price that is 20% less than the regular price. Write an expression that represents the sale price of an item if the
regular price is p dollars.
Dena said, "To find 20% of a number, I should multiply by 0.20. So the sale price of an item will be 0.20p."
Which statement best describes Dena's reasoning?
A Dena is correct.
Dena needs to subtract 0.20p from the regular price, p.
Dena should calculate the sale price as 20p and then divide by 100.
Dena is trying to solve an impossible problem because it doesn't say what the regular price is.

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0
