Answer:
the answer is 18
Step-by-step explanation:
Answer:
-1/6
Step-by-step explanation:
(10 - 8)/(-21 + 9)= 12/-12= -1
y - 8 = -1(x + 9)
y - 8 = -x - 9
y = -x - 1
Answer:
Constant of proportionality,
Step-by-step explanation:
Constant of proportionality states that the constant value of the ratio of two proportional quantities x and y,
it is written in the form of y = kx, where k is the constant of proportionality.
Given the equation: .....[1]
where r is the constant of proportionality.
From the table we consider
x = 14 and y = 1.4
Substitute these given values in [1] to solve for r;
Divide both sides by 14 we get;
therefore, the Constant of proportionality,
To start break even they need to sell 100 but if they want to make profit they need to sell 101 because you can use the equation y = .75x - 55
You can use midpoint formula
M=x1+x2/2 , y1+y2/2
M=-2+4/2 , 2+2/2
M= 1,2
