Answer:
35
Step-by-step explanation:
Answer:
Domain { -1,3}
Range { 2,5,6}
Step-by-step explanation:
The domain is the inputs or the x values
Domain { -1,3}
we dont list repeated values more than once
The range is the output values
Range { 2,5,6}
If the question is what part of her students have participated in. dance class before, it would be 49,15%, which is close to 50%, so 1/2 of the class..
I would think the answer is b because of that
I have no idea how did you get this result but I can show you the method of elimination. I think that it is the easiest way to solve the system of equations.
2 x + 3 y =105
x + 2 y = 6 /*(-2) // We will multiply 2nd equation by -2. That is because we want to cancel out the x`s//
2 x + 3 y = 105
-2 x - 4 y = -12 // Then we will add down these equations/ and x`s will cancel out//
3 y - 4 y = 105 - 12
- y = 93
y = -93
We can also solve x:
x + 2 * (-93)=6
x - 186 = 6
x = 6 + 186
x = 192
