Eva is showing her work in simplifying (7.3 − 7.2) − 3.8 + 3.7. In which step did Eva make an error? Step 1: (7.3 − 7.2) − 3.8 + 3.7

Step 2: 7.3 + (−7.2 − 3.8) + 3.7 (commutative property)

Step 3: 7.3 − 11 + 3.7

Step 4: 7.3 + 3.7 − 11 (commutative property)

Step 5: 11 − 11 = 0

Step 2; she wrote commutative instead of distributive
Step 4; she wrote commutative instead of distributive
Step 4; she wrote commutative instead of associative
Step 2; she wrote commutative instead of associative

step-by-step explanation:

the answer is 13/48

step-by-step explanation:

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
