Suppose f(x)=6x-2 and g(x)=2x+4). Find each of the following functions.

makvit [3.9K]

a. (f+g)(x) = 8x+2

b. (f-g)(x) = 4x-6

Step-by-step explanation:

Given

$f(x) = 6x-2\\and\\g(x)=2x+4$

$(f+g)(x)=f(x)+g(x)\\=6x-2+(2x+4)\\=6x-2+2x+4\\=6x+2x-2+4\\=8x+2$

$(f-g)(x)=f(x)-g(x)\\=(6x-2)-(2x+4)\\=6x-2-2x-4\\=6x-2x-2-4\\=4x-6$

Hence,

a. (f+g)(x) = 8x+2

b. (f-g)(x) = 4x-6

Roland receives $500 as a graduation present from his aunt. He plans to use part of the money to purchase a laptop for $289, inc

katrin [286]

Answer:

52x < $211

Step-by-step explanation:

If Roland uses $289 to purchase the laptop from the $500 that was given to him then he would be left with

500 - 289 = $211

With this he can purchase video games. Since each video game costs the same price of $52 then we can use the variable x to represent the number of games he can buy with the following inequality...

52x < $211
