Step-by-step explanation:
7 goes into 14 2 times
i believe your answers would be
1/2c+7 and 2H-9
Y - y1 = [-9-(-5)]/[(9-10] * (x - x1)
y - (-9) = [-9 + 5] / [-1] * (x - 9)
y + 9 = (-4) / (-1) * (x - 9)
y + 9 = 4(x - 9)
y + 9 = 4x - 36
y = 4x - 36 - 9
y = 4x - 45 This is the slope - intercept form.
y - 4x + 45 = 0 This is the standard form
Demand:
price quantity q(p)
p q
1 110
2 50
linear function:
q - 110 110 - 50
---------- = --------------
p - 1 1 - 2
q - 110
----------- = - 60
p - 1
q - 110 = - 60 (p - 1)
q - 110 = -60p + 60
q = - 60p + 170
Answer: demand equation: q(p) = 170 - 60p
Supply
price quantity
p q
1 50
2 110
linear function
q - 50 110 - 50
--------- = --------------
p - 1 2 - 1
q - 50
-------- = 60
p - 1
q - 50 = 60 (p - 1)
q - 50 = 60p - 60
q = 60p - 60 + 50
q = - 10 + 60 p
Answer: supply q(p) = - 10 + 60p
Price at which there is neither a surplus nor a shortage => equilibrium price
=> demand = supply
=> 170 - 60p = -10 + 60p
=> 60p + 60p = 170 + 10
120p = 180
p = 180 / 120 = 1,50
Answer: at $ 1,50
