Pretty sure the answer is F=4 2/3 I think
x - y = - 11 .............( 1 )
y + 7 = - 2x ...............( 2 )
from equation ( 1 )
x - y = - 11
x = -11 + y ...........( 3)
putting x in equation ( 2 )
y + 7 = - 2 x
y + 7 = -2 ( -11 + y ) y + 7 = 22 - 2 y y + 2 y =22 - 7
3 y = 15 y = 15 / 3
putting value of y in equation 3
x = -11+ ( 13 /5 ) x = -33 /3 + 15 / 3 ( l.c.m)
x = -17 / 5
check
x = -11 + y
- 17 / 5 = -11 + 13 / 5
-17 /5 = -17 / 5
Answer:
the transfer of energy from one organism to another
Step-by-step explanation:
1/2 [3logx + logy]
Step 1:
we use the property of n logx =log xⁿ for 3 logx
so 1/2[3logx +logy]= 1/2 [log x³ + log y]
Step 2:
We use another property here log a + log b = log (ab)
1/2[log x³y]
Step 3:
we again use the property of n logx =log xⁿ, bringing 1/2 in power
[log x³y]^1/2
√log(x³y)
so 2z-2 would equal -2
that means -2/x would have to equal 2
x=-1
x=z-A
z-A=-1
0-A=-1
A= 1
