Answer:
Rhe equation would be y= -2x+8
D the point of intersection is the solution
It could be multiple different answers. Any answer that will equal something higher than 8. Let's say (2, 5) for example. 2(2)+(5)>8 Two times two equals four plus five equals nine. Nine is greater than eight, therefore (2, 5) is true.
Hope this helps!
Answer:
-1
Step-by-step explanation:
let
i= Interest
p= Principle
r= rate
t= time
data given
i= $2520
p= $7000
t= 4years
r= ?
From the formula
i= prt
we make 'r' the subject by multiplying by pt both sides
i/pt=prt/pt
i/pt=r
its the same like
r=i/pt
r=$2520/($7000×4)
r=$2520/$28000
r=3/350
r=0.09%
therefore the interest rate is 0.09%
