we know that
One tens is equal to the number-----------> 
so
tens is equal to
therefore
<u>the answer is</u>
Answer:
emissions = 40·0.65^t
Step-by-step explanation:
The decay factor in an exponential equation is 1+(decay rate), so the equation can be written ...
amount = (initial amount)×(decay factor)^t
where the decay factor applies to 1 unit of time t. Filling in the given values, we find ...
decay factor = 1 +(-35%) = 0.65 . . . . for 1 year
emissions = 40×0.65^t . . . . . million tons, for t in years
Since bx does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting bx from both sides.
<span>-ay=-bx+2 </span>
<span>ax+by=3 </span>
<span>Divide each term in the equation by -1a. </span>
<span>y=(bx-2)/(a) </span>
<span>ax+by=3 </span>
<span>Divide each term in the numerator by the denominator. </span>
<span>y=(bx)/(a)-(2)/(a) </span>
<span>ax+by=3 </span>
<span>The equation is not linear, so the slope does not exist. </span>
<span>No slope can be found. </span>
<span>ax+by=3 </span>
<span>Since ax does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting ax from both sides. </span>
<span>No slope can be found. </span>
<span>by=-ax+3 </span>
<span>Remove the common factors that were cancelled out. </span>
<span>No slope can be found. </span>
<span>y=-(ax)/(b)+(3)/(b) </span>
<span>Divide each term in the equation by b. </span>
<span>No slope can be found. </span>
<span>y=(-ax+3)/(b) </span>
<span>Divide each term in the numerator by the denominator. </span>
<span>No slope can be found. </span>
<span>y=-(ax)/(b)+(3)/(b) </span>
<span>The equation is not linear, so the slope does not exist. </span>
<span>No slope can be found. </span>
<span>No slope can be found. </span>
<span>Compare the slopes (m) of the two equations. </span>
<span>m1=, m2= </span>
<span>The equations are parallel because the slopes of the two lines are equal.

Mentally your dividing the 12.50 by 10 and then thats 1/10 of it.
