Hint: You won't flip the sign in every problem. ONLY FUP it when you or by a 9 - 2x < 6x - 15 Solutions You solve and graph t
svetoff [14.1K]

You only flip the inequality sign when you multiply or divide both sides by a negative number.

================================================

Problem 1

3 - 8x \ge -29\\\\-8x \ge -29-3\\\\-8x \ge -32\\\\x \le \frac{-32}{-8} \ \text{ inequality sign flip}\\\\x \le 4

The inequality sign flip happens because we divided both sides by -8.

The graph will have a closed circle at 4 with shading to the left.

Three solutions are x = 0, x = 1, x = 2. You can pick any three numbers you want as long as they are 4 or smaller.

================================================

Problem 2

1x+2x-7 < 6\\\\3x-7 < 6\\\\3x < 6+7\\\\3x < 13\\\\x < \frac{13}{3}\\\\x < 4 \frac{1}{3}

The graph will have an open circle at 13/3 = 4&1/3 = 4.333 approx. The shading is to the left. No inequality sign flip happens because we divided both sides by a positive number.

Your choice of three solutions is correct. You can pick anything smaller than 4.3333

================================================

Problem 3

9-2x \le 6x-15\\\\-2x-6x \le -15-9\\\\-8x \le -24\\\\x \ge \frac{-24}{-8} \ \text{ inequality sign flip}\\\\x \ge 3

The solution set is any value 3 or larger. Three solutions are x = 5, x = 6 and x = 7.

The graph has a closed circle at 3 on the number line. The shading is to the right.

A sign in a bakery gives these options: • 12 cupcakes for $29 • 24 cupcakes for $56 • 50 cupcakes for $129 Find each unit price
crimeas [40]

Answer:

a) $2.44 per cupcake

b) $2.33 per cupcake

c) $2.58 per cupcake

Step-by-step explanation:

We are given the following in the question:

We have to calculate the unit price of the cupcakes.

Unit price =

=\dfrac{\text{Total Cost}}{\text{Number of cupcakes}}

12 cupcakes for $29

Unit price =

=\dfrac{29}{12}=2.43\text{ Dollar per cupcake}

24 cupcakes for $56

Unit price =

=\dfrac{56}{24}=2.33\text{ Dollar per cupcake}

50 cupcakes for $129

Unit price =

=\dfrac{129}{50}=2.58\text{ Dollar per cupcake}
