Answer:
<em>The values are a=6, b=8</em>
Step-by-step explanation:
The following system of equations
ax - by = 4
bx - ay = 10
Has the solution x=2, y=1. Substituting:
2a - b = 4 [1]
2b - a = 10 [2]
Multiply [1] by 2:
4a - 2b = 8
Add with [2]:
3a = 18
a = 18/3 = 6
a = 6
From [1]:
2*6 - b = 4
b = 12 - 4
b = 8
The values are a=6, b=8
Answer:
q= 2,550
Step-by-step explanation:
Giving the following information:
The demand function is q=-110p+7500.
<u>When the price is 0, the demand q is 7,500 units:</u>
p= 0
q= -110*0 + 7,500= 7,500
<u>Now, when the price is $45, the demand is:</u>
p= $45
q= -110*45 + 7,500
q= -4,950 + 7,500
q= 2,550
