The lines are parallel (meaning they have the same slope) so there is no solution. If the lines overlap then there is infinite solutions. If the lines cross there is one solution.
The only way to have more than one solution but not infinite is if the graphs are something other than lines.
Answer:
(p∘q)(5) = 2
(q∘p)(5) = -1
Step-by-step explanation:
The composition of functions can be written a little differently, perhaps making it easier to understand.
(p∘q)(x) = p(q(x))
(p∘q)(5) = p(q(5)) = p(2·5 -5) = p(5) = 5 -3
(p∘q)(5) = 2
__
(q∘p)(5) = q(p(5)) = q(2) = 2·2 -5
(q∘p)(5) = -1
Solution:
Consider the following expression:
2.5 x 8(20+5)
Solving the expression inside the parentheses first, we obtain:
2.5 x 8(25)
this is equivalent to:
2.5 x 200
this is equivalent to:
500
so that, we can conclude that the correct answer is:
500
Look, Dav...
This is a simple ex of Pyth. Theorem
26^2=24^2 + (DB)^2
then: DB = 10
