Answer:
x > 3
Step-by-step explanation:
Given
2(4 + 2x) < 5x + 5 ← distribute left side
8 + 4x < 5x + 5 ( subtract 5 from both sides )
3 + 4x < 5x ( subtract 4x from both sides )
3 < x ⇒ x > 3
The value of b is one. You just have to use the standard equation y = a + bx^2 + c. Get a, b, then c and from the given equation above you can derive a formula which is x is equal to the - b over 2 multiplied by a. if you get the value of x then substitute it to the equation and you will now get the value of b.
Answer:
Find the area of the semi circle with Diameter of 4
2π
6.3
Step-by-step explanation:
The area formula for semicircle is (πr^2)/2.
r=2 because radius is half of diameter.
(π(2)^2)/2, 2 squared= 4 and half of it is 2. = 2π
2π would round to the nearest tenths is 6.3.
The end result will not be the same as the beginning number because of the change in amounts in-between. Here's an example similar but easier
I have two dollars
I get half of it more
I now have three dollars
I give half of that away
Now I have a dollar and a half
It all depends on that the course if of the numbers
