Answer:
(x, y) = (7, -1)
Step-by-step explanation:
The expression for x makes it easy to use that for substitution.
3(-7y) +y = 20
-20y = 20 . . . . . collect terms
y = -1 . . . . . . . . . divide by -20
-7(-1) = x = 7 . . . use y in the second equation to find x
The solution is (x, y) = (7, -1).
Answer:
j
Step-by-step explanation:
Answer=10 10gram weights
10*10grams=100grams
therefore the weight would be even on both sides
slope intercept form = y=mx +b
where m would be the slope and b is the y intercept
equations would be:
cool cars: y = 179x +1999
awesome autos: y = 249x
