Given:
The equation is:

The graph of the
and
are given on a coordinate plane.
To find:
The solution of the given equation from the given graph.
Solution:
From the given graph it is clear that the graphs of
and
intersect each other at points (1.24,5.24) and (16,20).
It means the values of both functions
and
are equal at
and
.
So, the solutions of given equation are
and
.
Therefore, the correct option is only F.
Here is the answers for the first one
Answer:
for 18 x is 6 and for 20 it is 11
Step-by-step explanation:
For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6
For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11
