Answer:
f(-2) = 4
Step-by-step explanation:
The function has three definitions depending on the value of x.
You are looking for the value of the function at x = -2.
-2 is in the interval x <= -1, which is the first line of the definition of the function.
We use the first line of the definition of the function.
f(x) = -2x for x <= -1
f(-2) = -2(-2) = 4
Answer: f(-2) = 4
The equation for the sum of interior angles is :
Sum = (n-2) x 180, where n is the number of sides.
Replace sum with the given sum:
3960 = (n-2) x 180
Divide both sides by 180:
22 = n-2
Add 2 to each side:
24 = n
It has 24 sides.
For Each interior angle, divide the total sum by the number of sides:
3960 / 24 = 165 degrees
The interior and exterior angle needs to equal 180 degrees. To find the exterior angle, subtract the interior angle from 180:
180 - 165 = 15 degrees.

Step-by-step explanation:
Answer:
6 and -12
Step-by-step explanation:
6×-12=-72
6+(-12)=-6
×^2 -6x-72=0
(x+6) (x-12)
x^2-6x-72=(x+6) (X-12)
Answer:
<em>y</em><em> </em><em>=</em><em> </em><em>1</em><em>/</em><em>9</em>
Step-by-step explanation:
<em>To attain the y-intercepts you must let x</em><em> </em><em>=</em><em> </em><em>0</em><em>.</em>
<em>So</em><em> </em><em>in</em><em> </em><em>this case</em><em> </em><em>you will be</em><em> </em><em>having</em><em>:</em>
<em>y</em><em> </em><em>=</em><em> </em><em>(</em><em>3</em><em>/</em><em>2</em><em>)</em><em>(</em><em>0</em><em>)</em><em> </em><em>+</em><em> </em><em>1</em><em>/</em><em>9</em>
<em>So</em><em> </em><em>the</em><em> </em><em>coordinates</em><em> </em><em>will</em><em> </em><em>be</em><em> </em><em>(</em><em>0</em><em>,</em><em>1</em><em>/</em><em>9</em><em>)</em>
<em>hopefully</em><em> </em><em>this</em><em> </em><em>makes</em><em> </em><em>sense</em><em> </em><em>:</em><em>)</em>
