Answer:
Option (2)
Step-by-step explanation:
Equation of a line passing through a point (x', y') and slope 'm' is given by,
y - y' = m(x - x')
From the question in the picture attached,
Slope of the line 'm' = 
Line passes through a point (80, -71).
Equation of the line will be,
y + 71 = 
y = 
y = 
Option (2) will be the answer.
Step-by-step explanation:

Answer:
The set of factors of 20 is {1, 2, 4, 5, 10, 20} and the set of factors of 16 is {1, 2, 4, 8, 16}. {1, 2, 4, 5, 10, 20} ∩ {1, 2, 4, 8, 16} = {1, 2, 4} which has greatest value 4. So, GCF(20, 16) = 4.
Step-by-step explanation:
This is a formula if you need one. DON'T forget to cross-multiply
3/4 = x/12
Suppose x is sold, $280 each , and y is the total financial cost. The first equation in the system is then certainly y = 280x.
The vertex form <span>y-k = a(x-h)^2 where (h,k) is the vertex, and y is the y-intercept.
So, plug the values in.
</span><span>11,000-24,000 = a(0-500)^2
-13,000=250,000a
a=-0.052
y-</span><span>24,000 = -0.052(x-500)^2
y= </span><span>-0.052(x-500)^2 + 24,000
This is the second equation in the system.
The answer is then A, which contain the system </span><span>of equations which can be used to determine must be sold for the company to make a profit.</span>
