Answer:
18%
Step-by-step explanation:
Percent change can be found using the following formula:
Original represents the initial cost where new represents the new cost. We multiply the answer by 100 to get the percentage:
= 18%
Answer:
density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
Step-by-step explanation:
Between 8 and 10. Because the number graph goes in two's and not in one's, the odd numbers go in between the even numbers.
X, y - the numbers
The numbers add to 9 and multiply to -70.
The numbers are
-5 and 14.
1. A
Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines, there can be no solution. This is called an "inconsistent" system of equations, and it has no solution.

2. C
That's right. If a system of equations has a solution, then their graphs intersect, and the point where they intersect is the solution because it's the point that satisfies each equation in the system.
Straight-line graphs with the same slope are parallel lines, and they never intersect, which is another way of saying they have no solution.
