The typical form of the slope intercept equation would be:
Y = mX + B
Where b is the y intercept, thus in thus case the y intercept would be 65 = (0,65).
25 because each side is 5cm. So when you multiply length times width, you would multiply 5x5. So 25cm^2
I can help you, what do you need?
Your answer would be Dx=-4.
Here is why: log implies that the base is 10log10n=nlog10=n
Using the above two facts, you will be able to get:
<span><span>1100</span>=<span>10<span>−2</span></span></span>, so <span><span>log<span>(<span>1100</span>)</span></span>=−2</span>
<span><span><span><span>log10</span><span>x+2</span></span>=</span>x+2</span>
<span>x+2=−2</span>, so <span>x=−<span>4
</span></span>
First you need to simplify the ratio so divide 3 by 5, to come out with 1:0.6.
Then solve for the unknown then add the unknown to the known for the sum
