B.
–4

C.
2

D.
6

Answer 1

i only have five qestions

Answer 2

and i will fan and medal

Answer 3

But you should write the formula of the function.

Answer 4

i suck at math

Answer 5

Then, you only need to improve. But first, you should give us the formula of the function.

Answer 6

oh sorry here y=3x-1 x= -1

Answer 7

Well, the problem says, x=-1, so you should find the value of y when x=-1.

Answer 8

-4

Answer 9

Yes

Answer 10

can you help me with four more please

Answer 11

Ok, tell me

Answer 12

What is the value of the function v =3/2t - 5/2 when t = 3?

Answer 13

Same as before, put a 3 where the t is, and calculate the result.

Answer 14

Do you know how to sum these numbers?

Answer 15

is it 2?

Answer 16

Perfect!

Answer 17

Evaluate the function y = 20 – x when x = –3

A.
17

B.
60

C.
23

D.
–60

Answer 18

20- (-3) = 23?

Answer 19

Perfect!

Answer 20

Find the value of the function when n = 6.

p = 0.008n

A.
0.048

B.
0.0042

C.
0.48

D.
6.008

Answer 21

So, what do you think this time?

Answer 22

p=0.008 * 6= 0.048 so p=0.048

Answer 23

Yeah, perfect!

Answer 24

What is the value of the function when x = 6?

y = 4x + 5

Answer 25

4*6+5=29?

Answer 26

Perfect!

Answer 27

can you please oh please help me with more you got me to pass thank you thank you thank you

Answer 28

Ok, tell me

Answer 29

you sure im not being a bother

Answer 30

Answer 33

c?

Answer 34

I suppose these are two questions. The first one, the value of the function at x=-2, you can tell me the answer, but you should give me again the function if you want me to check it

Answer 35

no d?

Answer 36

no the link is the gragh

Answer 37

Ok, now I understand

Answer 38

i think its d?

Answer 39

You are right

Answer 40

It is D

Answer 41

What is the value of the function when x = 2?

x −4 −2 0 2 4
y 3 4 2 6 7

Answer 42

im lost on this one

Answer 43

+2

Answer 44

You should find the expression of the function. You know that, in general, a linear function is of the form\[y=mx+n\] where you can find the slope, and the intersection n. The intersection n can be find because when x=0, then\[2=n\]. You can find the slope, using,\[m=\frac{y_2-y_1}{x_2-x_1}=\frac{6-2}{2-0}=2\]. So the function is,\[y=2x+2\] And when x=2, then y is\[y=2\cdot2+2=6\]

Answer 45

omg thank you so very very very much

Answer 46

But don't worry, the problem is easier. You don't need to find all of that, simply find the x in the table and you will see that when x=2, y=6. See you.
