The value of f(8) and x is 28 and 4 respectively
<h3>Function and values</h3>
From the coordinate point (x, y), we can use the coordinate points (0,4) and (4,8)
For the sequence 0, 4...
f(x) = a +(x-1)d
f(x) = 0 + (x-1)(4)
f(x) = 4x-4
If the value of x is 8
f(x) = 4(8) - 4
f(8) = 32 -4
f(8) = 28
If the value of f(x) is 12
12 = 4x-4
16 = 4x
x = 4
Hence the value of f(8) and x is 28 and 4 respectively

Hoped that this helpedd!!
Find slope: (y2-y1)/(x2-x1)
(6-3)/(-5-0) = 3/-5 = -3/5
Equation: y = -3/5x + b
Plug in a point
3 = -3/5(0) + b, b = 3
Solution: y = -3/5x + 3
The question can't be answered without knowing how many red marbles and how many blue marbles are in the bottle.
The answer is option "A, 13".
As both triangles are similar.
<span>ΔRST ≅ ΔXYZ.
it means RS = XY
YZ = ST
and XZ = RT
Now given that RS = 13 which is equal to XY.
Thus XY is equal to 13.</span>
