What is the solution set to the inequality - 3x + 2 > 17

zepelin [54]

The answer would be x<-5

Explanation
You have to move 2 over to the 17 to get the x by itself so since it’s a positive 2, you would subtract 2 which would give you -3x>15. THEN you would divide the 15 by negative 3 which gives you -5 BUT since you are dividing by a negative you would flip the sign.
Hope this helped!!

Test yourself 2

mafiozo [28]

Ok, so dy/dx=0 at the point (0,3) that is where x=0 and y=3.

$\int { 6x+6dx } \\ \\ =\frac { 6{ x }^{ 2 } }{ 2 } +6x+C\\ \\ =3{ x }^{ 2 }+6x+C$

$\\ \\ \therefore \quad { f }^{ ' }\left( x \right) =3{ x }^{ 2 }+6x+C$

Now, f'(x)=0 when x=0.

Therefore:

$0=C\\ \\ \therefore \quad { f }^{ ' }\left( x \right) =3{ x }^{ 2 }+6x$

Now:

$\int { 3{ x }^{ 2 } } +6xdx\\ \\ =\frac { 3{ x }^{ 3 } }{ 3 } +\frac { 6x^{ 2 } }{ 2 } +C$

$={ x }^{ 3 }+3{ x }^{ 2 }+C\\ \\ \therefore \quad f\left( x \right) ={ x }^{ 3 }+3{ x }^{ 2 }+C$

But when x=0, y=3, therefore:

$3=C\\ \\ \therefore \quad f\left( x \right) ={ x }^{ 3 }+3{ x }^{ 2 }+3$

The function f(x)= (x– 4)^3

Andrews [41]

Answer:

Function f(x) is translated left 7 units and down 4 units

(x-4) --> (x+3)

+7 = translation left 7 units

-4 at end affects y (down 4 units)
