Answer:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
Substitute the x and y values in for x and y to check.
-1 = 7 - 8
-1 = -1
In this instance, (7, -1) is a solution of y = x - 8.
Answer: it would cost him $1660.16 to buy enough carpet for the room.
Step-by-step explanation:
The formula for determining the area of a square is expressed as
Area = L²
Where
L represents the length if each side of the square.
The sides of a square-shaped room are 4 meters long. This means that the area of the room is
4² = 16m²
If the carpet that Darnay wants to buy costs $103.76 per square meter, then the amount that it will cost to buy enough carpet for the room is
16 × 103.76 = $1660.16
Cut the figure into 2 parts, like you already have here.
There are now two parts with the dimensions of 3 x 3 and 2 x 9.
Multiply 3 x 3. That is 9.
Multiply 9 x 2. That is 18.
Add together 18 and 9. That is 27.
The answer is B, 27 in².
Hope this helps!
