Answer:

(x+9)(x-5)

x * x = x^2

9 * x = 9x

5 * x = 5x

9x + 5x = 14x

-5 x 9 = -45

x^2 + 9x + 5x -45

x^2 + 14x - 45

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

<u>a. (f+g)(x)</u>

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

<u>b. (f-g)(x)</u>

(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

Irma needs to rent a car for a business trip from phoenix to san jose (720 miles one way). she will drive round trip and will be
marusya05 [52]
To find the number of miles Erma can drive, you will write and equation and solve it to find the amount of miles that can be driven on $600 over the 1600 miles that are allowed.

Daily rate  + cost per mile over 1600 = total cost
(65 x 8) + 0.24m = 600
520 + 0.24m = 600
-520             -520
<u>0.24m </u>= <u>80</u>
0.24       0.24
m = 333.33... miles

The maximum number of whole miles she can drive would be 1933 miles (1600 + 333).

Jared can ran 4 miles in 1/2 hour. What is his average speed in miles per hour? (how many miles can he run in 1 hour)
evablogger [386]

Answer: His average speed is 8 miles an hour

Step-by-step explanation: First, two halves make a whole, so we simply multiply how many miles he ran in half an hour by 2!

4 x 2 = 8

Hope this helps :)
