Question

Below are two different functions, f(x) and g(x). What can be determined about their slopes?


f(x) Alex earns 1600 dollars in 400 hours.
x g(x)
1 −8
5 12
9 32
The function f(x) has a larger slope.

The function g(x) has a larger slope.

They both have the same slope.

The relationship between slopes cannot be determined.

Can I please get help with this question? I WILL GIVE MEDAL AND FAN!!

Answer 2

@ganeshie8

Answer 3

what is the slope of f(x)?

Answer 4

I don't know, that's what i'm stuck on

Answer 5

@jim_thompson5910

Answer 6

slope is the rate of change

Answer 7

it says "Alex earns 1600 dollars in 400 hours."

so the slope is 1600/400 = 4

this means he earns $4 an hour

Answer 8

what is the slope of g(x)

Answer 9

1,or 5 or 9?..

Answer 10

@jim_thompson5910

Answer 11

we have the two points (1,-8) and (5,12)

Answer 12

What is the slope of the line through (1,-8) and (5,12)

Answer 13

12-(-8)/5-1 = 20/4 = 5

Answer 14

the slope of f(x) is 4
the slope of g(x) is 5

Answer 15

Thank you! I have another question if u don't mind @jim_thompson5910

Answer 16

go ahead

Answer 17

A function is created to represent the balance on a credit card each month. What restrictions would be made to the range?

The range would only include integers.

The range would only include positive integers.

The range would only include negative integers.

The range would include all real numbers.
I was choosing between B or D but I'm going for D more.. am i wrong? @jim_thompson5910

Answer 18

can you have a negative balance on the credit card?

Answer 19

IDK.. lol i dont know anything about credit cards.. i've never had one, don't ever plan on having one in the future.

Answer 20

well credit is something you'll need in the future

and I'm reading that it is possible to get a negative balance

Answer 21

so D looks right

you can have values that aren't integers for the balance (like $19.02) so that's why B is only partially true

Answer 22

okayy and I have the answer for this one too and I just wanna make sure
