Answer:
<u><em>Variable terms:</em></u>
x and y
<u><em>Constant terms:</em></u>
7 and -9
<u><em>Coefficient terms:</em></u>
-5.6 and 24
Answer:
Step-by-step explanation:
<u>Given system of linear equations:</u>
<u>Add up the equations to eliminate y:</u>
- x + 2x = 90 + 105
- 3x = 195
- x = 65
<u>Find y:</u>
- y + 65 = 90
- y = 90 - 65
- y = 25
Answer:
A
Step-by-step explanation:
It looks like M is composed of all real numbers and that U = R also means its composed of all real numbers. This means that M and U are equal and both are composed of all real numbers.
To define the complement of M, it includes all values which are not in M. However, since M already has all real numbers and U doesn't have any values that M doesn't then the complement is nothing. It is an empty set with no items in it. This means A is the correct answer.
Answer:
b
Step-by-step explanation:
Answer:
514 days
Step-by-step explanation:
We use the formula (r+n-1)/r(n-1)
There are 1540 combinations. Then, we'll divide them by three because were not just finding the amount of combinations, but the time it'd take to play them all.
We get 513.333(cont.)
thats not really possible, so we're gonna go with 514 instead, rounding up. Normally we'd round down, because the number behind the decimal is below 5, but we really want to make sure we get every combination in there.
Hope this is helpful!
