Answer:
3x²(4x-3)
Step by step explanation:
Factorise 12x³-9x²
first, find the HCF of the terms.
the HCF is 3x²
Then you can use the HCF to multiply all terms, each divided by the HCF.
3x²(12x³/3x²-9x²/3x²)
Dividing, we'll have
3x²(4x-3)
Y = a |x-k|+h
a = slope it can be either vertical compression or vertical stretch
k = determines if a point should move right or left (x-axis)
h = determines if a point should move up or down (y-axis)
The answer to the question would be
y = - |x - 2.5|-7
Answer:
f(13) = 44
Step-by-step explanation:
f(13) = 3 (13) +5 = 39 + 5= 44
