Answer:
Step-by-step explanation:
9 - x ≤17
At some point you are going to have to turn the equation around. This would not normally be your first step, but this time it is better to start with it.
We won't do it directly. The best way to do it is to add x to both sides before you do anything else. This is not the usual way to solve these equations, but it's a good time to learn.
Inequality Rule: you must always solve for x. If it is -x then you are going to have to make an adjustment to get the x to be positive.
9 - x ≤ 17 Add x to both sides
9 - x+x ≤ 17 + x Combine
9 ≤ 17 + x Subtract 17 from both sides.
9 - 17 ≤ 17 - 17 + x
8 ≤ x
Notice that you have effectively changed the ≤ sign around, not because you have, but because the x reads differently now. It started out 9 - x ≤ 17 and when you finish solving it you get 8 is less than or equal to x. Entirely different.
Answer:
Area of the circle = 
Step-by-step explanation:
Radius of the circle= 
Area of the circle= 
As,
Area of the circle is:
The Area of the circle is :
To convert radians to degrees, make use of the fact that pi<span> radians equals one half circle, or 180º.</span>
<span>This means that if you divide radians by </span>pi, the answer is the number of half circles. Multiplying this by 180º will tell you the answer in degrees.
<span>So, to convert radians to degrees, multiply by <span>180/</span></span>pi, like this:
Degrees= radians X 180/pi
<span> </span>
Answer:
y = -x - 15
Step-by-step explanation:
x + y = -15
-x -x
y = -x - 15
