Answer:
f(f(x)) = 27
+ 18x² + 4
Step-by-step explanation:
To find f(f(x)) substitute x = f(x) into f(x) , that is
f(3x² + 1)
= 3(3x² + 1)² + 1 ← expand parenthesis using FOIL
= 3(9 + 6x² + 1) + 1 ← distribute parenthesis by 3
= 27 + 18x² + 3 + 1 ← collect like terms
= 27 + 18x² + 4
Answer:
16.
Step-by-step explanation:
There are 12 lillies which means that Faried planted 4 rows of rose bushes because 12 divided by the 3 lillies is four. 4x4= 16 rose bushes
Answer: −4x+2y−16
Step-by-step explanation: −2(2x−y+8)
=(−2)(2x+−y+8)
=(−2)(2x)+(−2)(−y)+(−2)(8)
<u>=−4x+2y−16</u>
120km.
Speeds that are travelling towards each other may be added together since we are looking for a total distance traveled.
If its parallel to y=2x-10, which has a slope of 2, the slope of the new line is 2 (the same slope).
use point slope form:
y - y1 = M (x - x1) where M is slope
y - 11 = 2( x -(-2))
y - 11 = 2( x + 2)
y - 11 = 2( x + 2)
y -11 = 2x + 4
y = 2x +4 +11
y = 2x + 14 has a parallel slope and goes through (-2, 11)
