Answer:
5, -5
Step-by-step explanation:
well 5-5 is 0 so that's it
:))))
Y=kx
Step 1: find the value of k
1/4=k(1/8)
k=2
Step 2: find the value of x using y=2x
y=2x
3/16= 2x
x= 3/32
Solved.
The first one is of order 5, so it has either 1, 3 or 5 real roots (unless any coefficent was complex). Proof complete :)
The other one, if it has a solution, it must be in [-1;1]. Because it only gives positive results the solution is further restricted to [0;1]. Because the cosine function is continuous and strictly decreasing on this interval, the difference of x and it's cosine will shrink up to some point within the interval where it gets to 0 (the solution) and then flips sign (the cosine gets less than the number), further decreasing until the end of the interval.
