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.
Answer:
a(a - b)
Step-by-step explanation:
<u>given </u><u>polynomial</u>: a²- ab - 8a + 8a
We can first simplify this answer by removing like terms,
- 8a + 8a = 0
so we have a²- ab in. the simplest form
we can take this one step further and factor out the a (not simplest form)
a time a = a²
a times b = ab
hence, a(a - b)

First you add 3 and 2 so that is 5 and then you subtract 5 from 9 so the answer is 4.
Answer:
b
Step-by-step explanation:
The range are the values that y can take.
From the graph we can see that all defined values of y are below the x- axis
Thus range is y < 0 → b
