Answer: x = 9.5

Step-by-step explanation:

3x - 12 = 5x - 31

First, add 31 to each side.

We get:

3x + 19 = 5x

Subtract 3x from each side.

We get:

19 = 2x

Divide both side by 2

9.5 = x

A function assigns the values. The graph can be plotted as shown below.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

Given the function, g(x) = -3(1/2)ˣ, therefore, the value of g(x) can be written as,

g(x) = -3(1/2)ˣ

g(-2) = -3(1/2)² = -0.75

g(-1) = -3(1/2)¹ = -1.5

g(0) = -3(1/2)⁰ = -3

g(1) = -3(1/2)¹ = -1.5

Hence, the graph can be plotted as shown below.

Eddi Din [679]
Total number of computers sold last week from Best Bargain = 340
Percentage of laptops sold last week from Best Bargain = 75%
These are the information's that we can find given in the question. Based on these information's the answer to the question can be easily found.
Number of laptops sold from Best Bargain last week = 340 * (75/100)
                                                                                     = 340 * (3/4)
                                                                                      = 85 * 3
                                                                                       = 255
So out of the total of 340 computers sold from Best Bargain last week, 255 were laptops. I hope this is the answer you were looking for.
