Answer:
4.5 i think
Step-by-step explanation:
<span>Sin(-x) = -sin x for all values of x, IT IS TRUE
Because sinx is an odd function</span>
First we need to find the slope of the function
The slope of a function is equal to

So now we plug this into the equation and find the slope (M will represent the slope)

So the slope is -3/2
Now we can use point-slope form.
Point slope form is represented by

So when we plug in our values we get

So the equation is
Y = -3/2X-7/2
By using the concept of profit, it can be calculated that
Profit function = 5.75 x - 1200
What is profit?
If the selling price of an article is more than the cost price of the article, the difference between the selling price and cost price gives the profit
Monthly expense for a pizza parlor C(x) = 1,200 + 6. 75x
Revenue function = 12.5x
Profit function = R(x) - C(x)
= 12.5x - (1200 + 6.75x)
= 12.5 x - 1200 - 6.75x
= 5.75 x - 1200
