Step-by-step explanation:
Answer:

Step-by-step explanation:
The method of variable substitution is a way of solving a system of equations. It involves solving one equation for a variable and then substituting in the expression that represents the value of the solved variable into the other equation. After doing so, one can solve for the unknown variable and then backsolve for the other variable.

In this system, the second equation is already solved for (y), thus one can substitute that expression into the other equation in the system.

Now solve using inverse operations,

Backsolve to find the value of (y), substitute in the value of (x), and solve for the value of (y).

Substitute,

Solve,

Thus, the answer to this system of equations is the following,
.
Answer:
-3.2 is the smallest integer
Step-by-step explanation:
For this case we have that the relationship is direct.
Therefore, we have:

Where,
y: distance traveled in kilometers
x: number of liters of fuel
k: proportionality constant
We must look for the value of k. For this, we use the following data:
This car can travel 476 kilometers on 17 liters of fuel.
Substituting values we have:

From here, we clear the value of k:

Therefore, the relationship is:

For 1428 kilometers we have:

Clearing the amount of fuel we have:

Answer:
51 liters of fuel are required for the vehicle to travel 1,428 kilometers
