Answer:
The point of equilibrium is (40,900).
Step-by-step explanation:
It is given that the supply and demand functions are linear.
From the given information it is noticed that the demand function passing through the points (40,900) and (60,700). The supply function passing through the points (30,550) and (50,1250).
If a line passing through two points, then the equation of line is

The demand function is



.... (1)
The demand function is
.
The supply function is



.... (2)
The supply function is
.
Equilibrium is the point where the demand and supply are equal.
On solving (1) and (2), we get


Therefore the point of equilibrium is (40,900). It means the retailer can buy 900 phones for $40 each and the wholesaler can sale 900 phones for $40.
d acute scalene is the correct answer...
Answer:
Dilate circle A by a scale factor of 4.
Step-by-step explanation:
To show that two circles are similar, use transformations to map one to the other.
<u>Step 1</u>
Translate circle A so that its center is the same as circle B.
- Center of circle A = (6, 7)
- Center of circle B = (2, 4)
Translate circle A using the rule (x - 4, y - 3)
<u>Step 2</u>
Find the scale factor needed to dilate circle A to the size of circle B using the radii of the circles.
- Radius of circle A = 4
- Radius of circle B = 16
⇒ scale factor = 16 ÷ 4 = 4
Dilate circle A by a scale factor of 4.
Therefore, the only answer option that is correct is:
Dilate circle A by a scale factor of 4.
