Substitute 1 for x in each of your equations.
f(x)=7-3x
which is
f(1)=7-3(1)
=3
Do the same for g(x)
g(x)=3x-7
which is
g(1)=3(1)-7
=-4
Then subtract g(x) from f(x):
3-(-4)
=7

Answer:
252 cubic cm
Step-by-step explanation:
V = (l x w x h ) / 3
V = (6 cm x 9 cm x 14cm) / 3
V = 756/3 = 252 cubic cm
Answer:
<h2>6.5</h2>
Step-by-step explanation:
Given the sum of the series represented as 
. <u>To get the sum to infinity of the geometric series, we need to get its first term and its common ratio</u>. comparing to the general term of the sum of series of a GP 
a = first term of the series
r = common ratio
On comparing to the given series, a = 1.3 and r = 0.8
Sum to infinity of a Geometric series is expressed as:
Supplementary because the line equals 180°
(x-21)+x
2x-21=180
2x=201
×=100.5°
