I believe you do it like this:
1/2 Q+5/2
divide 1/2 into each term
to divide multiply by the reciprocal
1/2 x2/1= 1
5/2 x 2/1=5
1/2(Q+5)
Answer:
Y=5X because the slope is 5 and the Y-intercept is 0
Find coordinate of points
Point P coordinates are (x,y) =
x is same that point L, y = 0 .
Then coordinates for P = (a,0)
Point M coordinates
x is same that point N, x=b
y is same that point L , y=c
Then coordinates for M = (b,c)
Answer:
The answer is A
Step-by-step explanation:
Answer:
2x^2 + 2y^2 + 2z^2
Step-by-step explanation:
x^2+xy-yx+y^2 + y^2+yz-zy+z^2 + z^2+zx-xz+x^2
First step is to put all the same ones together
( FYI, xy and yx is the same thing, just like how
2 x 3 and 3 x 2 is the same thing) this time I'll bracket the groups to make it easier on the eyes
(x^2 +x^2) + (xy - xy) +( y^2 + y^2) + (yz - yz) +
(z^2 +z^2) + (zx - zx)
2x^2 + 2y^2 + 2z^2
All the others just cancel themselves out, for example, xy-xy
When anything minus themselves it will become 0
