Answer:

2.85

Step-by-step explanation:

Amount Saved = $2.85 (answer). In other words, a 5% discount for a item with original price of $57 is equal to $2.85 (Amount Saved).

I dont like giving the answers to math questions, but the way in which your suppose to answer this is by finding the original price before the discount. To do this, turn the percent into a decimal (for five percent, 0.5) and divide the original price. This number should give you the discounted price! hope this helps you!

if a system of linear equation has an infinite number of solutions, what do you know about the graph of the system?

a. the lines intersect at one point
b. the lines are parallel
c. the lines are the same
d. the lines cannot he graphed

Answers

Answer:

c. the lines are the same

Step-by-step explanation:

A system of linear equations has an infinite number of solutions because the lines are the same. The correct answer would be an option (C).

What is the Linear equation?

A linear equation is defined as an equation in which the highest power of the variable is always one.

If a system of linear equations has an infinite number of solutions, it means that the equations are equivalent and represent the same line in the coordinate plane.

Therefore, the graphs of the two equations will be the same line, meaning that the lines are coincident. They won't intersect at one point, nor will they be parallel, as the definition of an infinite number of solutions is that they are the same line. And they can be graphed, as they represent a single line in the coordinate plane.

Hence, the correct answer would be option (C).
