Answer: The debt in 1999 is estimated to be 370.5 billions.
Step-by-step explanation:
Since we have given that
Amount the outstanding balance on a particular charge card in 1966 = $156
Amount the outstanding balance on a particular charge card in 2002 = $390
Let the number of year be x
and let the amount of outstanding balance be y
As we know the formula for "Slope ":
Here is the coordinates :(1966,156) and (2002,390)
now, we know the formula for "Equation of line":
Hence, the debt in 1999 is estimated to be 370.5 billions.
<span><span>Lets first solve the first one:</span></span>
<span><span>log<span>(x+9)</span></span>=<span>log<span>(2x−7)</span></span></span>
Convert the logarithmic equation to an exponential equation.
<span><span>10^<span>log<span>(x+9)</span></span></span>=<span>10^<span>log<span>(2x−7)</span></span></span></span>
Remember that <span><span>10^<span>logx</span></span>=x</span>, so
<span>x+9=2x−7</span>
Move values with 'x' to the right hand side.
<span>7+9=2x-x</span>
Combine like terms.
<span>16=x so,</span>
<span>x=16</span>
Check:
<span><span>log<span>(x+9)</span></span>=<span>log<span>(2x−7)</span></span></span>
If <span>x=16</span>
<span><span>log<span>(16+9)</span></span>=<span>log<span>(2<span>(16)</span>−7)</span></span></span>
<span><span>log25</span>=<span>log<span>(32−7)</span></span></span>
<span><span>log25</span>=<span>log25</span></span>
<span>x=16</span> is a solution.
Solve the second one like i solved this one, try it
49 %
465 + 485 = 950
465/950 = .489
.489 * 100 = 48.9, round up for 49 to get 49%, since it's only focused on people who tested positive, you would only have to compare the people in that column
Answer:
C
Step-by-step explanation:
You can let y for the inverse
Like
X =5y - 11
Then you will get
X+11=5y
Then x+11/5=y
