Step-by-step explanation:
First we find the function
g
(
f
(
x
)
)
To do this we substitute the variable
x
in
g
(
x
)
for
f
(
x
)
:
∴
g
(
x
)
=
3
x
−
2

Answer:
(3:-2) bc u must substitute -2 in for y in the 2th equation
Answer:
(1, 3 )
Step-by-step explanation:
To find a solution choose a value for x, substitute into the equation and solve for y.
let x = 1 , then
- 7(1) + 3y = 2 , that is
- 7 + 3y = 2 ( add 7 to both sides )
3y = 9 ( divide both sides by 3 )
y = 3
One possible solution is therefore (1, 3 )
Answer:
Postulate.
Step-by-step explanation:
If two distinct planes intersect, then their intersection is a line. This is a postulate.
A postulate is a true statement, which does not require to be proved.Postulate is used to derive the other logical statements to solve a problem.
Postulates are also called as axioms. Postulates are the basic structure from which lemmas and theorems are derived. Postulates are the most basic assumptions with which a reasonable person would agree.
