Answer:
cos = 3/5
sin = 4/5
Step-by-step explanation:
tan=4/3 Q1
if you use Pythagorean theorem
Becauseof Q1
c=5
to picture
sin = 4/5
cos = 3/5
Show that n is odd →∃m∈ℤ,n2=8m+1
Let k be an integer so that n=2k+1. Then n2=(2k+1)2=4k2+4k+1=2(2k2+2k)+1.
But this isn't equal to 8m+1, so can I change that into 4(2m)+1?

Answer:
A
Step-by-step explanation:
You switch the y and x and solve for y.
y = 2x + 5
becomes
x = 2y + 5
Subtract 5 on both sides.
x - 5 = 2y
Divide 2 on both sides.
(x - 5) / 2 = y
