Answer: x=7
Step-by-step explanation: (3x−2)=19
Add 2 to both sides.
3x=19+2
Add 19 and 2 to get 21.
3x=21
Divide both sides by 3.
x= [tex]\frac{21}{3}[/tex]
Divide 21 by 3 to get 7.
x=7
(2) 3x-2
The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of [tex]ax^{2}[/tex]
is [tex]nax^{n-1}[/tex]
.
[tex]3x^{1-1}[/tex]
Subtract 1 from 1.
[tex]3x^{0}[/tex]
For any term t except 0, [tex]t^{0}[/tex] =1.
3×1
For any term t, t×1=t and 1t=t.
answer=3
