Answer:
x = -4
Step-by-step explanation:
8x - 3 = 5(2x + 1)
8x - 3 = 10x + 5
8x - 10x = 5 + 3
-2x = 8
x = 8/-2
x = -4
Answer:
40
Step-by-step explanation:
10 + 30 = 40 difference
Answer:
121 degrees
Step-by-step explanation:
The "arc length" formula is s = rФ, where Ф represents the central angle in radians (not degrees).
Here r = 18 ft and s = 38 ft, and so:
38 ft
s = rФ becomes Ф = ------------ = 2.111 radians
18 ft
which, in degrees, is:
2.111 rad 180 deg
------------- * --------------- = 121 degrees, to the nearest degree

Answer:
- left 1 unit
- down 2 units
Step-by-step explanation:
The transformation g(x) = f(x -h) +k is a translation of f(x) to the right by h units and up k units.
1. h = -1, so the graph of g(x) is the graph of f(x) shifted left 1 unit. (blue)
__
2. k = -2, so the graph of g(x) is the graph of f(x) shifted down 2 units. (green)
Answer:
The inverse is 5/(2-x)
Step-by-step explanation:
Firstly, let us represent the inverse as y
thus;
y = (2x+ 1)/x-4
y(x-4) = 2x + 1
xy - 4 = 2x + 1
2x - xy = -4-1
2x-xy = -5
x(2-y) = 5
x = 5/2-y
Now, switch the alphabets again
y = 5/(2-x)
