Just plot the points on the graph so if x+y=-6 just make a list of all of the points that will work (remember that the left-to-right line is x and the up-to-down line is y, and right and up is positive and left and down is negative)
so make a list (in graphs we write [x,y] or (x,3)) so here are some points that will work
(-3,-3)
(-4,-2)
(-2,-4)
(-1,-5)
(-5,-1)
(0,-6)
(-6,0)
(-7,1)
(1,-7)
and so on, just plot those points and more that will work for x+y=-6 and you should be good,
there is another way that this is supposed to be done but this way is easier
Answer:
-3
Step-by-step explanation:
2/5(-10x+5)+8x=3(2x+6)-10
-20/5x+10/5+8x=6x+18-10
-4x+2+8x=6x+8
-4x+8x=6x+8-2
4x=6x+6
4x-6x=6
-2x=6
x=6/-2
x=-3
No! Of course not!!! Balls can be different sizes.......For Example......A football is not round...but the definition of a sphere is a round object.....A football isn't round
