1.) Let's say that the circle on the graph below represents x. The arrow is pointing to all the numbers greater than x, which happens to be on -2. If it points right, this means that x can equal to any number greater than -2. So your answer is x > -2.
2.) For inequalities such as these, you can simplify just like what you do for normal equations. Let's isolate x.

Answer:
437.999 + 0.001 = 438
Step-by-step explanation:
We have that
x²<span>+2x=17
</span><span>Group
terms that contain the same variable
</span>(x²+2x)=17
<span>Complete
the square. Remember to balance the equation
</span>(x²+2x+1)=17+1
Rewrite as perfect squares
(x+1)²=18
x+1=(+/-)√18
x=(+/-)√18-1
x1=√18-1----> 3.24
x2=-√18-1----> -5.24
the answer is
the option
<span>
4.) 3.24, –5.24</span>
Answer:
15 feet..
taking base as 8m
Given: ladder = 17 m and base = 8 m
The ladder forms a right triangle with the base of 8 m, the wall will be 15 m and the ladder (hypotenuse) is 17 m.
Let’s say you did not know that this was a standard 8–15–17 right triangle.
This is how you can figure it out:
hypotenuse(h)22 = side2112 + side2222
Let side11 = base and side22 = wall
1722 = 822 + wall22
wall = 172−82−−−−−−−√172−82
wall = 289−64−−−−−−−√289−64
wall = 225−−−√225
wall = 15 feet
