y< -1
To graph the above equation:
What is graph explain?
Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter. Each object in a graph is called a node.
Now, According to the question:
y is less than -1
The graph will be :

Answer:
7y=14. 2x - 4y = 18. (-3x + 2y = 1 ) 3. 2x+6y=18. -qx+6y=3. -7x=21 y=2. 3x + 5y =-5. 3x +0=-5. X=-3. 3x+2y = 1. 10. -10. -3x + 2y. 9+27='s. 끓들 x=-5. (-5,2) y=-4. 3.
Step-by-step explanation:
x=2(y+3). 3 x - 6 y = 18. 3x−6y=18. Add 6y to both sides. Add 6y to both sides. 3x=18+6y. 3x=18+6y
Answer:
20cm
Step-by-step explanation:
for the triangle:
Perimeter = 30cm
a + a + a = 30
3a = 30
hence a = 10cm
For the rectangle:
Perimeter = 30cm
a + a + b + b = 30
but a = 10cm
10 + 10 + b + b = 30
20 + 2b = 30
2b = 10
hence b = 5cm
Perimeter of square = b + b + b + b
= 5 + 5 + 5 + 5 = 20cm
Answer:
1/8 cup
Step-by-step explanation:
3/4 * 2 = 6/8
7/8 - 6/8 = 1/8
