ir y=-12 when x=9,find y when x=-4,

y=-12/9 X -4=5 1/3, so that: -12/9 : 51/3/-4

ir y=-12 when x=9,find y when x=-4

You are not given enough information to solve this.

You only know what y is when x=9.  You do not know what y is any other time.  

exact value of 3pi/4

Hi Rosala and Chris,

Thanks for digging that out Chris.

I was not aware that the thread was no longer a sticky topic.

I assume that Andre Massow removed it.  

I guess it was very dated.  There has been very little communication with Mr. Massow for  a long time.  

Recently Alan did request that Andre reintroduce the ability to see a member's posting history via the members personal member page.  We used to be able to do that and it was of great benefit to us.  As yet that has not happened.  I do not think there has been any other communication in months.

Simplify the following:
(4 a+4)^2-4×4 a^2

-4×4  =  -16:
(4 a+4)^2+-16 a^2

(4 a+4) (4 a+4) = (4 a) (4 a) + (4 a) (4) + (4) (4 a) + (4) (4) = 16 a^2+16 a+16 a+16 = 16 a^2+32 a+16:
16 a^2+32 a+16-16 a^2

Grouping like terms, 16 a^2-16 a^2+32 a+16 = 32 a+(16 a^2-16 a^2)+16:
32 a+(16 a^2-16 a^2)+16

16 a^2-16 a^2 = 0:
32 a+16

Factor 16 out of 32 a+16:
Answer: | 
| 16 (2 a+1)          =32a + 16

this is a math question? wow

exact value of 3pi/4

3pi/4 is just a number.  It is already an exact value.

Perhaps you mean sine, cos, or tan of 3pi/4?

it is realy a subtraction problem so take them and subtract

If the triangle is "right-angle" triangle the answer is "No". If it is NOT right-angle triangle, then the answer is "Yes".

it depends on what type of triangle you are trying to figure out is it a right triangle or what

Or, more directly: divide 12 grams by the number of atoms, which is the same thing:

12/(6.02 X 10^23)=1.993 X 10^-23 grams, the mass of 1 atom of Carbon 12.

the mass of 6.02 x 10(23) atoms of carbon is 12 grams. calculate the mass of 1 atom of cabon

6.02 X 10^23 atoms in 12 grams of Carbon, therefore,

(6.02 X 10^23) /12=5.02 X 10^22 atoms in 1 gram of Carbon,

1/(5.02 X 10^22)   =1.993 X 10^-23 grams-the mass of 1 atom of Carbon 12.

Press "2nd" key first. Then use "acos" key next. You may have to press = sign to get your answer.

1- Sine increases from -1 to 0

2-Cosine increases from 0 to 1

8000 (1+0.06/12)^108=13,709.60

If csc theta = -2 what is the value of sin theta ?

=Sin(theta)=-1/2

It sounds like a tangent relationship:

Tan(x)=50/35=1.42857..........

Atan(1.42857)=55.00 degrees.

|-3|.|-3|= ?, Does the (.) in the middle mean "Times"? If so then we have:

|-3|.|-3|= 9

Why is the variable "y" -5 in this equation? -(y+3)=2 And can you explain thoroughly please? Thanks in advance.

-(y+3)=2 remove the bracket from the left hand side,

-y-3=2 move 3 from left side to the right side and change the sign from - to +

-y=2+3

-y=5 multiply both sides by -1(- X - = +)

y=-5

Omg. You guys are really rude. People take their own time to answer these questions. BTW she is a moderator
