Question

Can someone quickly check 6 questions for me correct me if I did any wrong...I need to finish soon so I just want someone to correct me.

Answer 1

First one is wrong, I'm not sure on the second one. Keep forgetting radicals U.u

Answer 2

Yeah Radicals was the hardest thing for me to learn

Answer 3

Suppose you're given 16 ^ 7/9

The numerator is the exponent of 16
the 9 is the root,

Answer 4

Decent diagram of what it should be.

Answer 5

2 is D.

Answer 6

If u rewrite it, it is

7^1/3
-------
7^1/5

Using this rule, http://www.regentsprep.org/regents/math/algebra/ao5/rule_pdiv.htm

U get 7^2/15

Answer 7

is 1 is A? and thank you Nikato.

Answer 8

Yes 1 is A

Answer 9

Yeah 1 is A

Answer 10

I think you're right, 4 square is 2 and 25 squared is 5

Answer 11

Yea. Both look correct

Answer 12

It's decay because its below 1, anything below 1 is decay.. anything above 0.99 is growth

Answer 13

Okay thank you

Answer 14

np

Answer 15

OHH WAIT I was confused!!

See the y intercept of g(x) is when x is 0, when x is 0, the y intercept is left alone :D

So because the y intercept of f(x) is 3 and the y intercept of g(x) is 6 then its 2 times the y intercept of f(x).

3 * 2 = 6

Answer 16

The y intercept of g(x) is 2 times the y intercept of f(x) ._.

Answer 17

Wait so when there is a 0 the y intercept is left alone?

Answer 18

When x is 0, thats how you find the y intercept.


To find the y intercept, set x for 0
To find the x intercept, set y for 0

Answer 19

Suppose your asked to find the y intercept of 3x + 2y = 12

Set x for 0,

3(0) + 2y = 12
/2 /2

y = 6


You can pretty much find the x from plugging in your y, 3x + 2(6) = 12

3x + 12 = 12
-12 -12

3x = 0
/3 /3

x = 0



3(0) + 2(6) = 12

0 + 12 = 12

12 = 12 :D

Answer 20

Okay thank you this is very helpful! You're really good! I'm so sorry to bother you but i have to get a good grade on this mind checking like 2 more? so sorry!!

Answer 21

Sure, i gtg soon :p like next 10 min

Answer 22

What did you put for number 5?

Answer 23

C

Answer 24

C is correct.
the first function is f(x)=5^2
second is g(x)=-3

and then together 5^2 -3

Answer 25

for the other one, change it to slope intercept form and grpah it

so y=-3x+10. can u try grphing this?

Answer 26

yes

Answer 27

Is it C? sorry I might have graphed it wrong.. I am not really good at this.

Answer 28

no. its not right. however part of it is right. the graph does not contain the origin, however, it should be a slolid line

when grapging, the >= sign means solid line where as just > means dotted line

Answer 29

Ohh thank you!! (:

Answer 30

yea. and just to let u know, ur graph should have look something like this

Answer 31

Answer 32

oh nevermind, but if u want to look at it, just type in ur function

Answer 33

Okay thanks
