Answer:
1000
Step-by-step explanation:
Doing this on a calculator yields 1000.
Alternatively, do part or all of the problem in your head:
Rewrite 42 ÷____= 0.042 as
42
------------
0.042
and move the decimal points 3 place to the right:
42 becomes 42000, and 0.042 becomes 42. Thus, we have:
42000
------------ = 1000
42
YOUR ANSWER IS 15i radical 6
Answer:
both choices with 2x+y = -3
Step-by-step explanation:
to have the solution (-4, 5), that point must be on both equations/functions, meaning it must be on either one.
in other words, if the point is not on at least one of the functions, it cannot be a solution for that system.
the given function
2x + y = -3
looks like for the point (-4, 5)
2×-4 + 5 = -3
-8 + 5 = -3
-3 = -3
correct.
but
-2x + y = -3
looks like for (-4, 5)
-2×-4 + 5 = -3
8 + 5 = -3
13 = -3
wrong. the point is not on this function.
as we can therefore rule out 2 of the answer options, the other 2 most be correct.
