Answer:
- 2n + 6
Step-by-step explanation:
note that + (-) = -
5n + 6 + (- 7n)
= 5n + 6 - 7n ← collect like terms
= 5n - 7n + 6
= - 2n + 6
The graph of f(1/2x) is a horizontal expansion of the graph of f(x) by a factor of 2. The mapping rule is (x, y) -> (2x, y)
(-4,2) -> (-8,2)
(-2,-2) -> (-4,-2)
(0,0) -> (0,0)
Plot those points to get the graph of f(1/2x).
How to solve systems of linear equations by graphing?
<span>To solve a system of equations graphically, graph both equations and see where they intersect. The intersection point is the solution. The slope intercept method of graphing was used in this example. The point of intersection of the two lines, (3,0), is the solution to the system of equations.</span>
Answer:
260.0234 cm
Step-by-step explanation:
The formula for area of a circle is π r².
Since the radius is half of the diameter, we must divide the diameter by 2.
18.2/2 = 9.1
Next, we must multiply 9.1 x 9.1.
This gives us 82.81
Now we must multiply 82.81 by pi (3.14).
82.81 x 3.14 = 260.0234
Therefore, the area of the circle is 260.0234.
