Answer: 5
Step-by-step explanation:
We know that when a liner function is represented by a graph i.e. by a line, then its initial value is represented by the y intercept of the line.
In the given graph , we can see that the y-intercept of the function is point (0,5).
The y -intercept of the function :
Then , the initial value of the function will also be 5.
Hence, the initial value of the function represented by this graph=5

To solve this proportion, cross multiply.
By cross multiplying, you will multiply 2.75 * (2/9) and 9 * x.
0.61 = 9x
Divide both sides by 9.
x = 0.067... which rounds to 0.068, so your answer is:
D) x 0.068
Answer:
y=250x+300
Step-by-step explanation:
Let x be the number of heaters and y be the total cost.
We need to find the linear function for y in terms of x.
It is given that company can produce 15 heaters for $4050 and 25 heaters costs $ 6550.
It means the line passes through the points (15,4050) and (25,6550).
If a line passes through two points and
, then the equation of line is
The equation of line is
Add 4050 on both sides.
Therefore, the required linear function is y=250x+300.
