What is the constant of proportionality in the equation y =2.5xy=2.5 xy
2 answers:
Answer: 2.5
Step-by-step explanation:
We know that the constant of proportionality is the ratio between two directly proportional quantities.
The equation of direct variation between two quantities x and y is given by :-
, where k is the constant of proportionality,
The given equation : -
When we compare to the general direct variation equation , we get
hence, the constant of proportionality in the equation 2.5

Answer:
The image of both graphs can be seen below:
Both functions will have the same output for an input x₀ if:
f(x₀) = g(x₀)
This means that, for that particular value of x₀, the functions will intersect each other.
So we just need to look at the graph and find the x-value where the functions intersect. (Remember that the x-values are in the horizontal axis)
We can see that it happens at x = 1.
Then the input value that produces the same output value for the two functions is:
x = 1
