Answer:
- 2x³
Step-by-step explanation:
f(x) - g(x)
=
- x - (2x³ -
- x) ← distribute parenthesis by - 1
=
- x - 2x³ +
+ x ← collect like terms )
= - 2x³
Answer:

Step-by-step explanation:
Solve the inequality 
Use distributive property:

Subtract 4s:

Subtract 14:

Divide by -6 (do not forget to change sign, because division by negative number changes the sign):

Answer:

Step-by-step explanation:
<u>Answer</u>:
c = 9
<u>Explanation</u>:
given: f(x)=3x-7
<em>if f(c) =20</em>
To solve this replace x with c and then y is 20.
<u>Solve</u>:
3c - 7 = 20
3c = 27
c = 27 ÷ 3
c = 9
