10 to the sixth power is 1,000,000. Any number to the tenth power is the number 1 in front of the number of zeros that is equal to the exponent.
Answer:
x = 3, y = -4
Explanations:
The given system of linear equations is:

The graph representing the equations is plotted below:

The point where both lines intersect is the solution to the system of equations.
The lines intersect at the point (3, -4), therefore, (3, -4) is the solution to the system of equations
Given:
limit of $36 and 20 pounds of food in his back pack
pasta : 1 pound package @ $1
pasta sauce: 1.5 pound jar @ $3
x = number of pasta package
y = number of jar of pasta sauce
Constraint on the weight:
x + 1.5y <u><</u> 20
Constraint on the cost of purchase.
x + 3y <u><</u> 36
Your adding 5 every time :)
