Step-by-step explanation:
to make y=-4 from -12 you have to divide by 3. so divide the 9 by 3 to get 3 which is your answer
Answer:
73.7
Step-by-step explanation:
14 +14 +23+22.7=73.7
your answer is a ok i hope this helpful
Answer:
It’s y2-y1 over x2-x1
Y2 is 5 and y1 is 5
5-5
X2 is 7 and x1 is -2
7- negative 2
5-5 is 0
7- negative 2 is 9
Slope is 0

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
