- Factor this?
*By*:-Kara

Plz show work. And factor don't solve. (X)^3(y)^2 + 4(x)^2(y)^2 -12x - 1 algebra question?
*By*:-Kara

Plz explain! (1-x)/x + (3-x)/(x-2) - Arithmetic series 2n+7??
*By*:-Olive

the question is "find the sum of the first five terms of the arithmetic series an=2n+7" . Please help me find the answer, I really can t figure this one out... Thanks! - What is the number of ordered pairs (X Y) where X and Y are nxn real matrices such XY-YX=I?
*By*:-Sourav

There are no such pairs.

Proof by Contradiction:

If X and Y exist such that XY - YX = I, then taking traces yields

tr(XY - YX) = tr(I)

==> tr(XY) - t - find the exact expression for the following tan(cos^-1(x/4))?
*By*:-Evan

At first glance I would have to guess x=pi. However I'm not sure where to begin to answer this question. If I remember correctly I believe solving this would involve drawing the triangle? - Which of the following could be the equation for a parabola that opens down with vertex (-11, -28)?
*By*:-crnio031109

A. x = 5(y + 11)^2 - 28

B. x = -5(y + 28)^2 - 11

C. y = -5(x + 11)^2 - 28

D. Y = 5(x + 28)^2 - 11 - Find the domain of the function. (Using interval notation.)f(t) = (sq. root of t+8)How do I know how
*By*:-flor

You can easily setup an interval notation from an inequality:

If lower bound is included, use [, otherwise use (.

If upper bound is included, use ], ot - Help me solve? Math?

A pair of dice is rolled. What is the probability of getting a sum less than 6

? - What is: 5(17)² / 10³ =?
*By*:-Mark

5(17)² / 10³ = 5 * 289 / 1000

= 1445/1000

= 1.445

1.4450000000...

5 x 289 / 100 = 1445 / 100 = 14•45

5(17^2) / 10^3

Function Operations Simplest Form?

Given the funtions f(x) = 3x+1 and g(x) = x-2, determine the equation of h(x) in simplest form for the next two questions.

a) h(x)= f(x)+g(x)

b)h(x)= f(x) / g(x) - Given point A (2, 4) and point B (8, 10), find the coordinate of point P on the directed line segmen
*By*:-Oleydis Claro

The point that partitions the line segment A to B into a ratio of a:b is (bA+aB)/(b+a).

Point P is (1(2, 4)+5(8, 10))/(1+5) which evaluates to (7,9).

- Math Help :( Easy, elementary school-question, just really stumped. 10 points!?
*By*:-ZandraBabyy

So we have to solve this equation for find y-intercept with the given slope:

y-(-3)= -7/5 (x-3)

(also note, the entire 7/5 value is negative, not just one number: it seems kind of unclear written here-see pic)

Here are the steps to the correct answer - Convert 2.5 radians to degrees, and express the answer to the nearest minute?
*By*:-Brandon

i figured out that 2.5 radians equals 143 degrees, but i dont understand what i don't understand the second part, what does the "nearest minute" mean? - How many natural numbers n are there such that the number n^2+2n+29 is a square of some natural numb
*By*:-ayy

m > n > 0

n²+2n+29 = m²

(n+1)²+ 28 = m²

m²-(n+1)² = 28

(m+n+1)(m-(n+1)) = 28 = uv

m+n+1 = u

m-(n+1) = v

m = (u+v)/2

n= (u-v)/2 - 1 > 0 - There exists an integer n such that 6(n*n)+27 is prime?
*By*:-fasi

No

Nope.

6 times something is divisible by 3.

27 is divisible by 3.

Answer is divisible by 3.

Certainly not. Obviously the expression - . There exists an integer n such that 6n2 +27 is prime?

Just confused on simplifying. (3x^3 - 6x^2) / 3x - Find the roots?
*By*:-Cookie

1/3 squared equals negative 5x -18

...I think it leads to finding the product of 54 with a sum of 15..but 3 and 18 can't equals 15 if their both positive! - What do the letters inside the grid of a Punnett square represent?
