Substituting the value y from the 2nd equation onto equation 1
Therefore, the linear equation does not have a solution.
You can eliminate r by multiplying equations 1 by 5 or equation 2 by 2.
3.Using cramer’s Rule D=(30 6
The determinant = A= -5.-6. -11.6=96
2 -11). The determinant=30.-11-2.-5=b= –320
Factorize 1/v and it will cancel with the one to the right
Divide by LCM = n2-12n = n48/n2-12n
n2-12 n will cancel
Addition of equation 1 to 14 and 2nd to 4 for elimination
S= The price of each strawberry =$12
P=Price per Peacan =8
Addition of 2nd equation to eliminate
S=price per eeach strawberry =$19
P = Price of each New York =$15
To eliminate x, multiply 2nd equation by 15.
$18750 = y=money for govt-insured bonds
x=money from non-insured bonds =$31250
b. Revenue function=600x=500000+200x
Tickets = X
TRUE.g multiply equation 1+y=8 by 2.
The solution will vary from 8 to 16.
FALSE- elimination refers to a method of eliminating the leading equation of the first equation from each other equation. However, it does not replace the latter equation with the sum.
TRUE- A system that consists of equations involving two variables could have solutions.
TRUE- Marginal cost is a variable in a linear cost equation.
TRUE – An “inconsistence system” is a system that consists of linear equations with no solution.
