How do I graph this problem X+2y= -2

aleksandr82 [10.1K]

If you have an app like Desmos, you can just input that. If not, you would subtract X from both sides to get 2y=-x-2. Then, you would divide by 2 on both sides to get y=-1/2x-1. You can input that into Desmos or a graphing calculator. Please mark me brainliest, but its fine if you don’t want to. Have a good day!

Answer:

a) attached

b) 100 square inches, 1/4 of the total

c) square root of area

d) multiply by 4

Step-by-step explanation:

a) A diagram is attached

b) If the total area consists of 4 squares of the same size, then the area of one square will be 1/4 of the total area. 1/4 of 400 square inches is 100 square inches, the area of one square.

c) The area of a square is the square of the side length. You find the side length by finding the square root of the area. √(100 in²) = 10 in, the side length of each square.

d) The rectangle is 4 squares laid side by side, so its length is 4 times the side length of one square: 4×10 in = 40 in.
