<u>Answer:</u>
- The numerator '9's share is 450 and the denominator '7's share is 350.
<u>Step-by-step explanation:</u>
<u>Step-1: Add the ratios:</u>
- 9 + 7
- 16
<u>Step-2: Divide 800 by the sum of the ratios:</u>
- 800 ÷ 16
- => 50
<u>Step-3: Multiply 50 with each ratio:</u>
- 9 x 50 = 450
- 7 x 50 = 350
Hence, <u>the numerator '9's share is 450 and the denominator '7's share is 350.</u>

Answer:
Range is {y | y ≥ –11}
Step-by-step explanation:
This is quadratic equation.
<em>A quadratic equation's range can be found if we find the vertex.</em>
For quadratic equations that have a positive number in front of , it is upward opening and thus <u>all the numbers greater than or equal to the minimum value of vertex is the range.</u>
The formula for vertex of a parabola is:
Vertex =
Where,
is the coefficient of
is the coefficient of
From our equation given, and
Now, coordinate of vertex is
coordinate of the vertex IS THE MINIMUM VALUE that we want. We get this by plugging in the
value [
] into the equation. So we have:
Hence, the range would be all numbers greater than or equal to
Third answer choice is the right one.
