Martha spent $38.45 on a new shirt and now has $17.71 in her pocket. which equation can be used to find how much money, x, she had in her pocket before buying the shirt? a. x−38.45=17.71 b. x + 38.45 = 17.71 c. x + 17.71 = 38.45 d, 17.71x = 38.45

d, 17.71x = 38.45

x - 38.45 = 17.71  

x = 17.71 + 38.45

x = $56.16  ( Martha had in her pocket before buying the shirt )

A )  x - 38.45 = 17.71

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

answer: (1,3) (3,-1) (5,-5) ?
