Answer:
Step-by-step explanation:
We have been given that Nikki can drive her car 22 miles on each gallon of gasoline. We are asked to write the expression that represents the number of gallons used when Nikki drives 'm' miles.
To find the number of gallons used we will divide the total distance traveled by distance traveled in one gallon.
Since Nikki traveled 'm' miles and car travels 22 miles on each gallon of gasoline, so the expression represents the number of gallons used.
Answer: h = 9
Step-by-step explanation: A system of linear equations is consistent when it has at least one solution.
The matrix given is:
Transform this matrix in a row-echelon form:
For this row-echelon form to have solutions:
-9 + h = 0
h = 9
For this system to be consistent: h = 9.
