Answer:
A system of linear equations can have no solution, a unique solution or infinitely many solutions. A system has no solution if the equations are inconsistent, they are contradictory. for example 2x+3y=10, 2x+3y=12 has no solution. is the rref form of the matrix for this system.

Answer:
108
Step-by-step explanation:
Limit as x approaches 9 of x^2 -81/sqrt of x - 3
First substitute x into the expression
= 9²-81/√9 - 3
= 81-81/3-3
= 0/0 (indeterminate)
Apply l'hospital rule
= lim x -> 9 d/dx(x²-81)/√x - 3
= lim x -> 9 2x/1/2√x
Substitute x = 9
= 2(9)/1/2√9
=18/1/(2(3)
=18 × 6/1
= 108
Hence the limit of the function is 108
Answer:
1.375 pounds
Step-by-step explanation:
We want to find how many pounds of candy he has left.
He bought 5 pounds.
He gave out 3 pounds.
He ate 10 ounces. Converting 10 ounces to pounds:
1 ounce = 0.0625 pounds
10 ounces = 10 * 0.0625 = 0.625 pounds
Therefore the amount of candy he has left is:
5 - (3 + 0.625)
= 5 - (3.625)
= 1.375 pounds
