False. Time is usually represented on the horizontal axis.

This is because the independent variable usually goes on the horizontal/x axis and the dependent variable goes on the vertical/y axis. The independent variable is what you're changing and usually time is what affects whatever outcome (aka dependent variable value) you get.

What is f left parenthesis 4 right parenthesisf(4) for the function f left parenthesis x right parenthesis equals 2 x plus 6f(x)

I am Lyosha [343]

Answer:

$f(4)=14$

Step-by-step explanation:

Given function is $f(x)=2x+6$

We need to find the value of $f(4)$

For any function $f(x)$ if we want to find the value of $f(a)$ , we need to plug $x=a$ in the function.

So, we will plug $x=4$ in the function $f(x)=2x+6$

$f(4)=2(4)+6\\f(4)=8+6\\f(4)=14$

So, the value of $f(4)$ in the function $f(x)=2x+6$ is $14$

$200 in the ratio 1:2:2 working out

gtnhenbr [62]

Answer: 40:80:80

Step-by-step explanation:

The ratio is 1:2:2. This means, for every 5, the money is split in a ratio of 1:2:2. Let’s calculate how many 5s there are in 200. 200 / 5 = 40. So, the money will be split in 1:2:2 every 5 dollars 40 times.

Excellent. So, we can easily find out the ratio by multiplying the ratio 1:2:2 by 40. 1*40:2*40:2*40 = 40:80:80. Let’s add these up, and see if they result in 200. 40 + 80 + 80 = 200. So, our answer is correct.

Hope this helps!
