Answer:
Anwers are top to bottom:
1. y − 2,000 = 2,000 + 320x − 2,000
2. division property of equality
3. Y - 2000/320 = X
4. 10,000 - 2,000/360 = 25 = x
Step-by-step explanation:
F(x) is a quadratic equation with the x-side squared and a is positive which means that the graph of the function is a parabola facing up. The range of f(x) is given by {y|y ≥ k}, where k is the y-coordinate of the vertex.

, written in vertex form is

, where (h, k) = (-1, -11)
Therefore, range ={y|y ≥ -11}
Answer:
989000
Step-by-step explanation:
Divide 2,967 ÷ 0.003
First, we are going to find the sum of their age. To do that we are going to add the age of Eli, the age Freda, and the age of <span>Geoff:
</span>

The combined age of Eli, Freda, and Geoff is 40, so the denominator of each ratio will be 40.
Next, we are going to multiply the ratio between the age of the person and their combined age by <span>£800:
For Eli: </span>
For Freda:
For Geoff: 
<span>
We can conclude that
Eli will get </span>
£180,
Freda will get £260, and
Geoff will get <span>
£360.</span>
The answer to ur problem is 3.5x10^3
