Question 161984: In y=4x, what happens to y ehn x is doubled?increased by 2?decreased by 3?halved?
a) Lets double x: so x becomes 2x
y=4x
y=4(2x)
y=8x....y is doubled
b) Lets increase x by 2; so x becomes x+2
y=4x
y=4(x+2)
y=4x+8 so y increased by 8
c) Let x be decreased by 3 so x becomes x-3
y=4x
y=4(x-3)
y=4x-12....so y is decreased by 12
d) Let x be halved, so x becomes x/2
y=4x
y=4(x/2)
y=4x/2..... so y is halved Answer by eperette(173) (Show Source):
