Answer:
Step-by-step explanation:
We are given the following in the question:
Area of room =
Area of rug =
We have to find the area of of the room not covered by the rug.
Area of of the room not covered by the rug =
Area of room - Area of rug
is the required expression for the area of floor not covered by the rug.
So, this is kind of a hard concept to explain without any pictures, but I'll try anyways.
Think of a plane as like a sheet of paper, and a line as a metal rod.
If I want to intersect the plane, it means that my line (rod) has to touch the plane (paper).
If I poke the rod through the paper, it only intersects it in one place, and I cannot fold or warp the paper to change that.
The only other way I can make these two touch is if I lay the rod on top of the paper. However, when I do this the paper is touching every single point along the rod...
I hope this kinda helps explain why you can never intersect in exactly two points.
Answer:
The integers are -3 and -4.
Step-by-step explanation:
Two consecutive integers are an integer and the one just greater or just less than the4 first one, such as 5 and 6, or -8 and -9.
If the smaller integer is x, then the next greater integer is x + 1.
x + 1 = 4x + 13
-3x = 12
x = -4
x + 1 = -3
Answer: The integers are -3 and -4.
Check:
Smaller integer: -4
Larger integer: -3
4 times smaller integer = 4 * (-4) = -16
13 greater than 4 times smaller = -16 + 13 = -3 = greater integer
-3 and -4 is the correct answer.
Answer:
Step-by-step explanation:
2x - 5y = 10
2(-3.5) - 5y = 10
-7 - 5y = 10
+7 +7
-5y = 17
-5 -5
y = -3.4
The value of y is equal to A. -3.4.
