<span>The correct answer is a negative correlation. This means that as one increases, the other decreases. In this case, as the age of a car increases, its value decreases. On a graph this will look like a line going down from the top left to the bottom right. A positive correlation would be the opposite (as one increases, so does the other). A constant correlation means that something is increasing or decreasing at a steady rate (since we don't know how much a car's value depreciates each year, we can't determine if it's a constant relationship). </span>
Answer:
I'd help if i knew how to do that
Step-by-step explanation:
$30.75
is taxes sale total is 330.75
What we need to do with this problem is multiply the amount the computer costs ($350) by the tax rate (6%). To do this, we first need to convert the percentage to a decimal, so we divide the 6 given by 100, leaving us with .06. Next, we need to multiply the $350 by the .06, giving us $21 as the amount we should be paying for sales tax. So your answer should be 2) $21.00!
<em>multiply both sides by 5 </em> 3(15k+10)=5(12k-9)
<em>get rid of the brackets</em> 45k+30=60k-45
<em>take away 45k to both sides</em> 30=15k-45
<em>plus 45 to both sides</em> 75=15k
<em>divide both by 15</em> k=5
