Answer: g(f(4))=9

Step-by-step explanation:

To find g(f(4)), you first find f(4). Then, you plug it into g(x).

f(4)=4-7 [subtract]

f(4)=-3

Now, we know f(4) into g(x).

g(f(4))=(-3)² [exponent]

g(f(4))=9

Now, we know that g(f(4))=9.

Given F(x)=1/x-4, g(x)=1/6-x. Find f+g(x).

$\boxed{f(x)+g(x)=\frac{1}{x}-x-\frac{23}{6}}$

<h2>Explanation:</h2>

We are given two functions:

$f(x)=\frac{1}{4}x-4 \\ \\ g(x)=\frac{1}{6}-x$

So, we have to find $f(x)+g(x)$ which is the sum of these two functions:

$f(x)+g(x)=\frac{1}{x}-4+\frac{1}{6}-x \\ \\ \\ Let's \ call \ h(x)=f(x)+g(x) \\ \\ Simplifying: \\ \\ h(x)=\left(\frac{1}{x}-x)+(-4+\frac{1}{6}) \\ \\ \\ \\$

$Finally: \\ \\ \boxed{f(x)+g(x)=\frac{1}{x}-x-\frac{23}{6}}$

A robot can complete 8 tasks in 5/6 hour. each task takes the same amount of time.

nikklg [1K]

5/6 hour = 5/6 × 60 = 300/6 = 50 minutes

8 tasks in 50 minutes
1 task = 50/8 = 6 1/4 minutes

a. robot completes task in 6 1/4 minutes

b. #tasks per hour =
#of tasks × time takes to do task < or = 60
n × 6.25 = 60
6.25n = 60.
n= 60/6.25 = 9.6

robot can complete 9 tasks in one hour

Hannah drove 310 miles in 5 hours ,while tom drove 177 miles in 3 hours .which of them drove faster ?

vlada-n [284]

First off you need to make a equation with 310/5 = 177/3

you then divided 310 by 5 and 177 by 3
310 divided by 5 = 62
177 divided by 3 = 59

the answer you get represents how many miles they traveled per hour.

Hannah drive faster.
