Question

What is the equation of the line that passes through the point (1, 6) and has a slope of 3?

y = 3x + 5

y = 3x + 3

y = 3x - 17

y = 3x - 5

Answer 1

y=3x+3

Answer 2

Can you help me with a few more?

Answer 3

yea sure no problem

Answer 4

Which relation does not represent a function?

(-9, 3), (-2, 1), (1, 3), (5, -6)

(2, 0), (4, 8), (7, 5), (1, 5)

(-6, 2), (2, 5), (-4, 0), (2, 6)

(-4, 6), (-1, 1), (0, 4), (4, 7)

Answer 5

the second one doesn't represent a function. A function is only One to One.

Answer 6

it's the second one.

Answer 7

@agutie I have already said this!!

Answer 8

Oh wait I see, it has a number in there twice.

Answer 9

yes

Answer 10

yes this is correct!

Answer 11

What is the slope between the two points (4, 14) and (2, 4)?

1/5

5

-1/5

-5

Answer 12

5

Answer 13

Okay that's what I thought.

Answer 14

yes

Answer 15

Which equation is not equivalent to the formula r = st?

s=r/t

t=r/s

s=t/r

r = ts

I think it's the second one.

Answer 16

s=t/r

Answer 17

How? I don't understand these & I'm prepping for an exam.

Answer 18

if you try to get on variable by itself you do the divsion. and check the answers that are given to you and see if they match or not.

Answer 19

Ohh! I see now. At least you explain it clearer.

Answer 20

ok. its not that difficult if you understand it very well.

Answer 21

If f(x) = x2 + 3, find f(5).

13

22

28

4

I got 28 this is how:

f(x)=x^2+3
f(5)=5^2+3
f(5)=25+3
f(5)=28

Answer 22

@Sceenie yes.!

Answer 23

Awesome! :D

Answer 24

:D you get it now.!

Answer 25

Solve for x: 3x - 2 > 5x + 10

x > 6

x < 6

x < -6

x > -6

I got x < -6

3x-2>5x+10
+2 +2
----------
3x>5x+12
-5x -5x
----------
-2x>12
-- --
-2 -2
x < -6

Answer 26

Yes.!! :D

Answer 27

Can you explain this one a little bit?

The set of ordered pairs below defines a relation. In each ordered pair (x, y), x represents the daily wages of a plumber, and y represents the daily wages of her assistant.

{(144, 72), (171, 84), (198, 84), (171, 96), (144, 72)}

What is the difference between the values of the least and greatest elements in the domain of this relation?

24

54

72

126

Answer 28

I think it's 54, cause if I'm understanding it right, I just have to subtract the numbers in the ordered pair.

Answer 29

54

Answer 30

and yes

Answer 31

Simplify 4(2u - 3).

8u - 12

8u + 12

8u - 3

6u - 7

I think it's : 8u-3

Answer 32

8u-12

Answer 33

you have to distribute the 4 to the whole equation

Answer 34

Wait lol i forgot to distribute the other side. xD

Answer 35

yes cx

Answer 36

Simplify the following expression.
7x - 4y + 5z - 2x - 10y + z

5x - 14y + 6z

9x - 14y + 6z

5x - 6y + 6z

9x - 6y + 6z

I think it's :5x-14y+6z

7x - 4y + 5z - 2x - 10y + z
7x-2x-4y-10y+5z+z
rx-14y+6z

Answer 37

You there?

Answer 38

x-6
--- = 5
4

I got x = 26

Answer 39

yes. sorry. yes that's right
