The points P(-2,1), Q(-6,4), and R(4,3) are three vertices of a parallelogram PQRS.
Find the coordinate S.-Slope of PQ = (4-1)/(-6+2) = -3/4
Slope of QR = (3-4)/(4+6) = -1/10
Slope of RS = Slope of P
-6x +5y=1
6x+4y=-10
i need to know what x and y is. these two equations are with the same problem.-Just add the equations to get
9y=-9 so y=-1
Substitute y=-1 into either equation and solve for x,
Express (√8+√50)/√490 as a simple surd fraction with a rational denominator.
I have got this to 7√2 / 7√10 and do not know how to get a rational denominator from a surd.-(sqrt(8) + sqrt(50)) / sqrt(4
standard deviation s. 10% of them have mass greater than 900 kg and 15% of them have mass less than 500 kg. Find the mean x and the standard deviation s.-P(X ≥ 900) = 0.1
P(X ≤ 500) = 0.15
P((X - μx
2. 4x + y = -9
4x+ 2y = -10
4. -4m + 2n = 6
-4m + n = 8
8. s - t = 4
s + t = 2
10. -4x + 2y= 8
4x - 3y = -10

Im studying for the math placement test for my future high school. The book says find the inverse of if not p, then q I think it is if p, then not q but the book says its if p, then q.
Im confused I
so its a simple thing my book says where
well use:
t for theta
p for pi
z for a general complex number
j = (-1)^0.5
e^(z+2npj) = e^z
so lets look at this:
e^(z+2npj) = e^z * e^(2npj)
= e^z * (cos(2p
