13
explanation: 85^2=84^2+B^2
7225=7056+B^2
169=B^2
square root 169 and it’s equal to 13
I believe the answer would be y = –3x – 1.
Answer: 300 is the answer
Step-by-step explanation:
It’s 4 I think sorry if I’m wrong
We have that
<span>Log3 a/3
</span>Rewrite log3(a/3) using the change of base <span>formula
we know that
</span>The change of base rule can be used if a and b are greater than 0 and not equal to 1, and x is greater than 0<span>.
</span>so
loga(x)=<span>logb(x)/<span>logb<span>(a)
</span></span></span>Substitute in values for the variables in the change of base <span>formula
</span>
in this problem
b=10
a=3
x=a/3
log3(a/3)=[log (a/3)]/[log (3)]
the answer is
[log (a/3)]/[log (3)]
