What is the domain and range for this graph?

1 answer:

8 0

Informally, the domain is the set of all possible elements in a set for which there is one and only one output. In interval notation, the domain is (-4, ∞). I am assuming it continues on infinitely to the right because of the arrow. The range is [1, ∞). Here, you choose the lowest value on the graph, up to the highest one.

X+y= -9 x+2y= -25 According to the system of equations above, what is the value of y?

Varvara68 [4.7K]

Try this option:
if x+y=-9 is I (one)
and x+2y=-25 is II (two), then
if II-I, then (x+2y)-(x+y)=-25+9 ⇔ y=-16.
