Answer:
infinitely many solutions
Step-by-step explanation:
We want to find solution to the system:
-4y=-20x+40
y+10=5x
We make y the subject in the second equation to get;
y=5x-10
We substitute y=5x-10 into the top equation to get:
We expand to obtain;
This implies that:
Therefore the system has infinitely many solutions.
Answer:
510-165=345.
Step-by-step explanation:
Well if you subtract 510-165 you would get 345. Therefore your answer would be " There are 345 marbles that are not in the jar."
Answer:
need points...sorry
Step-by-step explanation:
X=6 and x=-8
To solve this, you would treat x-6=0 as one equation, you add 6 to each side to get rid of -6, hence you would get x=6.
Same goes for x+8=0, subtract 8 from each side to get rid of the +8, then you get x=-8
