Joshua wants to burn at least 400 calories per day, but no Which are possible solutions for the number of minutes
more than 600. He does this by walking and playing Joshua can participate in each activity? Check all that
basketball. Assuming he burns 4 calories per minute apply.
walking, w, and 5 calories per minute spent playing
basketball, b, the situation can be modeled using these
40 minutes walking, 40 minutes basketball
inequalities:
60 minutes walking, 20 minutes basketball
4w + 5b 2 400
4w + 5b s 600
20 minutes walking, 60 minutes basketball
50 minutes walking, 50 minutes basketball
60 minutes walking, 80 minutes basketball
70 minutes walking, 60 minutes basketball

step-by-step explanation:

both equations and proportions are better.

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
