it is c. because the function is not a dependent or independent variable
Revenue = Sales Volume (x) times Price. Price depends on volume sold: the more you are willing to sell per week, the lower your average price will have to be to get them all sold.
<span>eg, if there are a fixed number of buyers with a variety of incomes, then you might be able to sell the first 10 per month for £30 each through the up-market High Street jeweller. If you want to sell an extra 10 per month you might have to reduce the price to £15 and sell them through Asda/WalMart. And to move another 10 per month you may have to sell them from a street stall at £5 each! </span>
X+x^2=2
x^2+x-2=0
(x+2)(x-1)=0
So x=-2, 1
Answer: y = 4x + 13
Step-by-step explanation:
y = 4x + 10
First find the slope m
y = mx + C
y - intercept point y
m - slope
x - intercept point x
C - intercept point
From the equation,
slope m = 4
Using the formula for slope
y - y_1 = m(x - x_1)
Given point ( -2 , 5)
x_1 = -2
y_1 = 5
m = 4
Inserting the values given
y - 5 = 4 ( x -(-2))
y - 5 = 4(x + 2) ( point slope form)
y - 5 = 4x + 8
y = 4x + 8 + 5
y = 4x + 13 ( slope-intercept form)
y = mx + C ( slope - intercept form formulae)
Answer:
-2x
