WHAT IS ITTTT 3d + 9 = 27

Mathematics

Dominik [7]3 years ago

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{d = 6}}}}}

Step-by-step explanation:

\sf{3d + 9 = 27}

Move 9 to right hand side and change its sign

\dashrightarrow{ \sf{3d = 27 - 9}}

Subtract 9 from 27

\dashrightarrow{ \sf{3d = 18}}

Divide both sides by 3

\dashrightarrow{ \sf{ \frac{3d}{3}  =  \frac{18}{3}}}

Calculate

\dashrightarrow{ \sf{d = 6}}

Hope I helped!

Best regards! :D

Answer:

d = 6

Step-by-step explanation:

3d + 9 = 27

Subtract 9 from each side

3d + 9-9 = 27-9

3d = 18

Divide each side by 3

3d/3 = 18/3

d = 6

What is the axis of symmetry for f(x) = −3x2 + 12x − 6?
Marta_Voda [28]
The axis of symmetry can be found by finding the average of the zeros, a derivation from the conservation of energy :P, or by finding the point when the velocity is equal to zero.

df/dx=-6x+12 so df/dx, velocity, equals zero when:

-6x+12=0

6x=12

x=2  so the axis of symmetry is the vertical line x=2

....

average of zeros...

3x^2-12x+6=0

x^2-4x+2=0

x^2-4x=-2

x^2-4x+4=2

(x-2)^2=2

x-2=±√2

x=2±√2  so the average of the zeros is obviously 2.

....

conservation of energy

vf-vi=at  When vf=0, this is the maximum value for f(x)...

-vi=at, vi=b and a(acceleration)=2a(from quadratic) and t=x

-b=2ax

x=-b/(2a)  in this case

x=-12/(2(-3))

x=-12/-6

x=2
