Xavier sells homemade necklaces for a profit of $22 per necklace. he is considering switching to a new type of pendant that will increase his profit, as expressed by the function y=29x, where x is the number sold and y is the amount of profit. how many more dollars will xavier earn on each necklace if he switches to the new material?

$7 more

Step-by-step explanation:

According to the question, Xavier sells homemade necklaces for a profit of $22 per necklace .

Now, he’s considering switching to a new type of pendant that will increase his profit as expressed by

y = 29x

Where x = number sold and

y = amount of profit

From the expression, if he sells one necklace made with the new type of pendant ,

y = 29 x 1

= $29

Remember he makes $22 per necklace already .

$ earns if he switches to the new pendant = $29 - $22

= $7

He’ll earn $7 more if he switches to the new material

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
