Oh yeah, i didnt have enough room up there, how would you solve 3a= -1/4 ?thanks :)-If you divide both sides with 3 you will have: 3a/3= -1/4 *1/3
a = -1/12-If you multiply both sides of the equation
On my online math class, they set up a table for finding variance and standard deviation
x sub i~x sub i-mean~(x sub i-mean)^2
Even though they set up the table like this, they sometimes subtract th
v^2-7v= -10-v2-7v=-10
v2 -7v - 10= 0
(v-5) (v-2)= 0
v=5, v=2-There are 2 ways. The first by using the rule for the discriminant Δ =b^2 - 4ac. First we turn out equation in the form of ax^2 + bx + c =
3y-6x=12
y-2x=4
Honestly... no idea how to do this, we did it early this quarter but i need to know for my final...-Theres infinitely many solutions, because if you convert both of the equations to s
The problem:
log(a) x=3/2 log(a) 9 + log(a) 2
Please tell me step by step how to do this? I missed a day of class and I dont have time to talk to the teacher...
Thanks!-So a is the base of these log
Find the length of the major/minor axis for the ellipse defined by this equation.
(x+1)^2/64 + (y+1)^2/36 = 1
Please explain in simple terms.-(x+1)² / 64 + (y+1)² / 36 = 1
The major axis will be re
Given f(x) = 2x² + 4x -3, find f(3). thanks
can u also help me with another question which is:
5m² +8m + 1 = 0
i have to use the x= -b√b² - 4ac / 2a
thnx-f(3)=27
Just plug the 3 in where all the xs
So my teacher gave us an extra credit problem to do and nobody has any idea how to do it. However, she said we could ask any (Accelerated) Algebra II Student so I appeal to you, my lovely reader.
You
Together Marc and Paoli have $32. Marc has $4 less than twice the amount Paoli has. How much does each man have?-You have two equations:
Marc + $4 = 2(Paoli) or put differently Marc = 2(Paoli) - $4

So, my homework problem says, Solve the following equation for m. p = 6n - 5m/14.
My answer was m = 6n/5 - 14p/5
I checked my answer on an online calculator, and it said the answer was
m = 2 (7p -

State the degree of 9 + 4x(squared) = 6x(cubed) + x(to the fourth) - 7x-x^4 - 625 = 0
(x^2 - 25)(x^2 + 25) =

x - y = 4
please show work I dont know how to do this my math teacher sucks and we having a test on it on friday :/ so hopefu
Final review question...ugh.-Suppose an isomorphism existed, f:Z->Q. What would map to 1/2?
Say f(n) = 1/2, and f(m) = 2. Since its an isomorphism, these must exist. Then f(n)f(m) = f(nm) = 1/2*2 = 1
