Answer:
18x^2 - 9
Step-by-step explanation:
y = f(x)= 6x^3 - 9x + 4
dy/dx = d/dx(6x^3) - d/dx(9x) + d/dx (4)
=6.d/dx(x^3) - 9.d/dx (x) + d/dx. (4)
=6.3x^2 - 9.1 + 0 =18x^2 - 9
Answer:
x is greater than or equal to -4
Step-by-step explanation:
I am not sure if I have to graph as well so I will just solve the inequality.
3x-12 greater than or equal to 7x+4
+12 +12
3x is greater than or equal to 7x+16
-7x -7x
-4x is greater than or equal to 16
-4x/-4 16/-4
x is greater than or equal to -4
The answer is c thank me later
Answer:
8. the length is 88/5cm or 17.6cm
Step-by-step explanation:
8.perimeter =2L + 2W
when you convert the width 42/5 = 8.4
so 52 = 2L + 2*8.4
52= 2L + 16.8
52 - 16.8 = 2L
35.2 = 2L
divide both sides by 2
L = 17.6cm
