noo..

Answer 6

do you know what it is?

Answer 8

please someone help :)

Answer 9

What is a linear function?
A linear function has the form of y=a+bx, do any of the choices look like that?

Answer 10

where is power of x and y are 1 and non negative is liner polynomial

Answer 11

oh ok.. so
c?

Answer 12

no

Answer 13

Let's look at each one
y=3x^2
y=1/3x
y=x^3+5
(2/3)x=y-1 let's solve for y so we have y=(2/3)x+1

which one looks like y=ax+b?

Answer 14

To put it more clearly
\[y=3x ^{2} ; y=\frac{ 1 }{ 3x } ; y=x ^{3}+5 ; y=\frac{ 2 }{ 3 }x+1\]

Answer 15

um, A?!

Answer 16

@plainntall ?

Answer 17

It is the last one.
\[\frac{ 2 }{ 3 }x=y-1\]
The biggest hint is that it has x and y, the others have x squared, x to the -1 power, x cubed

Answer 18

D?

Answer 19

Remember that a linear equation looks like
y=ax+b

y=ax^2 is not linear because it has x squared
y=1/(3x) has the x in the denominator so it isn't linear
y=x^3+5 has x cubed so it isn't linear

only (2/3)x=y-1 which can be written as y=(2/3)x+1 looks like y=ax+b where a is 2/3 and b is 1.

Answer 20

Yes D

Answer 21

ohhhhhh i get it now.. thanks so much!! i have one more question :)

Answer 22

Let's think about what happens in each segment
P the distance is increasing with time
Q the distance does not change with time
R the distance is increasing faster with time than in P
S the distance decreases with time

Where do you think the cyclist stopped moving and rank the water from that information.

Answer 23

Q?

Answer 24

Great, good job. So that means the cyclist completed what segment before Q where she stopped and drank the water?
