Answer:
x + 2y = -8 = y = -4 - 1/2x
y= -1/2x + 4 = y = 4
y= -1/2x - 4 = y = -4
y=-2x - 4 = y = -4
y=1/2x-4 = y = -4
Step-by-step explanation:
(x + 2y = -8 = y = -4 - 1/2x)
![x+2y=-8\\2y=-8-x\\y=-4-\frac{1}{2}x\\](https://tex.z-dn.net/?f=x%2B2y%3D-8%5C%5C2y%3D-8-x%5C%5Cy%3D-4-%5Cfrac%7B1%7D%7B2%7Dx%5C%5C)
Answer:
The Customer Acquisition Cost for each customer in demographic group 1
The correct option is c
The Customer Acquisition Cost for Group 2
The correct option is b
Step-by-step explanation:
From the question we are told that
The marketing expenses per month for targeting the first group is ![E = \$ 30,000](https://tex.z-dn.net/?f=E%20%3D%20%20%5C%24%2030%2C000)
The marketing expenses per month for targeting the second group is ![F = \$ 60,000](https://tex.z-dn.net/?f=F%20%3D%20%20%5C%24%2060%2C000)
The number of customers for the demography of group 1 that will be attracted is N = 1000
The number of customers for the demography of group 2 that will be attracted is M = 1500
Generally the customer acquisition cost for group 1 is
![K = \frac{E}{ N}](https://tex.z-dn.net/?f=K%20%20%3D%20%20%5Cfrac%7BE%7D%7B%20N%7D)
=> ![K = \frac{30000}{ 1000}](https://tex.z-dn.net/?f=K%20%20%3D%20%20%5Cfrac%7B30000%7D%7B%201000%7D)
=> ![K = \$ 30](https://tex.z-dn.net/?f=K%20%20%3D%20%5C%24%2030%20)
Generally the customer acquisition cost for group 2 is
![Z = \frac{F}{ M}](https://tex.z-dn.net/?f=Z%20%20%3D%20%20%5Cfrac%7BF%7D%7B%20M%7D)
=> ![Z = \frac{60000}{ 1500}](https://tex.z-dn.net/?f=Z%20%20%3D%20%20%5Cfrac%7B60000%7D%7B%201500%7D)

Answer:
sorry icant open the picture my phone is lagging
In a parallelogram sum of the adjacent angles
equals supplementary.
opposite angles are equal.
Let the smaller angle = x°
larger angle = twice the smaller angle - 30°
=2x° - 30°
x° +2 x° - 30 = 180°
3x° = 180 + 30
3x = 210
x = 210 / 3
x = 70°
Therefore,
smaller angle = x = 70°
larger angle = 2x - 30
= 2 × 70 - 30
= 140 - 30
= 110°
Required parallelogram angles are 70° , 110° ,
70° , 110°
I hope this helps you.
