Answer:
2√6
Step-by-step explanation:
I will be honest with you and say that I'm not sure if it is right or not.
Answer:
y=1/2x
Step-by-step explanation:
if a linear equation has a parallel function then it's going to have to be the same slope as the equation. ie
y=2x+3
and
y=2x-2
are paralell
Answer:
Solving mathematics isn't as difficult as we think.All you have to do is follow the steps and practice more questions
practice makes perfection
Answer:
s = 6, r = 8 or s = 4, r = 7
Step-by-step explanation:
2r - s = 10
2r = 10 + s
r = 5 + s/2 --(1)
rs - s^2 = 12 --(2)
sub (1) into (2):
(5 + s/2)s - s^2 = 12
5s + 0.5s^2 - s^2 = 12
-0.5s^2 + 5s - 12 = 0
s^2 - 10s + 24 = 0
(s - 6)(s - 4) = 0
therefore s = 6 or s = 4
when s = 6, r = 8 and when s = 4, r = 7
if you would like to discover more about simultaneous equations, you can have a look at my Instagram page (learntionary). I'll be posting mathematics related stuff there and some of my notes (simultaneous enq notes are already posted!)
(10(1-(1/2)^5)/1-(1/2) =
20(1-1/32)
=155/8
