42x + 28y......the GCF is 14...so factor out 14
14(3x + 2y) <==
7-foot
EXPLANAT
Given:
14 foot tree
8foot shadow
4foot shadow
Let h be the height of a tee that casts a 4 foot long shadow.
Using proportion;
14 foot = 8 ft shadow
h = 4 ft shadow
Cross - multiply
8h = 56
Divide both-side by 8
h = 7 foot.
Hence, the tree is 7-foot.
the domain of the graph is where on the x axis there is a graph.
here the domain, x, is less than or equal to 6, isnce it goes down on the negative side
the arrow means the line goes on forever, so
x<=6
(x is less than or equal to 6)
