Answer: k≤ - 11
explanation: move constant to the right handed side and change its sign, then calculate the differences, then you get that
The tens column is the one directly to the right of the decimal, so you need to get rid of the seven. Since the 7 is closer to ten than it is to zero (it's bigger than 5), you will round up. When you round up, you add 1 to the number on the left, the 9. So it will become 10, or 1.0
Pythagorean theorem: a² + b² = c²
a² and b² are the legs, and c² is the hypotenuse.
Plug in 9 to a² and b² since you know that both the right triangle's legs are 9 cm.
9² + 9² = c²
81 + 81 = c²
162 = c²
Square root both sides.
c = 12.7 cm
Answer: (-6,-4) (-2,-2) (-1,0) (2,6)
Step-by-step explanation:
We can see that points (2,0) and (4,1) isn't plotted on the line
X=1 so you need to add and it will be c=9
