Answer:
0
Step-by-step explanation:
f(x) = 2/5(6 - x)²
f(6) = 2/5[6 - (6)]²
f(6) = 2/5(0)²
f(6) = 0
Hello, I will try my best to explain this to you as simple as possible.
First, you have to pass the -4 to the other side, like this:
-3 1/2x - 4 = -38 1/8
↓
-3 1/2x = -38 1/8 - 4
Then, you have to subtract -4 from -38 1/8, like so:
-3 1/2x = -38 1/8 - 4
↓
-3 1/2x = -42 1/8
My preferred method for this next step is this:
-3 1/2x = -42 1/8
↓
-7/2x = 337/8
Then, we divide:
-7/2x = -42 1/8
↓
x = (-337/8) / (-7/2)
x = 12.0357142857
So, the answer is: 12.0357142857.
Hope this helped! c:
Answer:
The mean absolute deviation (MAD) of her Math scores would be 1.2.
Step-by-step explanation:
Mean: 5.4 + 6.4 + 7.8 + 8.8 = 28.4/4 = 7.1
7.1 - 5.4 = 1.7
7.1 - 6.4 = 0.7
7.1 - 7.8 = 0.7
7.1 - 8.8 = 1.7
Mean Absolute Deviation: 1.7 + 0.7 + 0.7 + 1.7 = 4.8/4 = 1.2
hope this helps :)
Answer: x=2
Step-by-step explanation:
2(x+3)-4x=x
2x+6-4x=x
-2x+6=x
-2x-x=6
-3x=-6
x=2
Answer:
<d = 25 degrees and <e = 130 degrees
Step-by-step explanation:
We have a vertical angle, so the opposite sides of this angle are the same. This means that the angle opposite to 25 degrees also measures 25 degrees. We have one angle of the triangle. Since the triangle is isosceles, the angle d is the same as 25 degrees.
<d = 25 degrees
The interior angles of a triangle add up to 180 degrees, and we now have 2 angles, so:
<e = 180 - 25 - d
<e = 155-25
<e = 130 degrees
