The correct answer choice is:
______________________________________________
[C]: "<span>Multiply each side by −8, subtract 35 from each side" .
_______________________________________________
Explanation:
_______________________________________________
Given: "</span>
(x + 35) = -7 " ;
We can START by multiply each side of the equation by "-8" to completely get rid of the "" fraction on the "left-hand-side" of the equation:
since: " * -8 = 1 ; and: "1" , multiplied by any given value, is equal to that given value; so in effect, the "1" becomes eliminated.
" * -8 =
* 
=
= 
= 1 .
____________________________________________________
So, given: " (x + 35) = -7 " ; ;
We multiply each side of the equation by "-8" ;
→ -8 * { (x + 35) } = -7 * {-8) " ;
→ 1 (x + 35) = 56 ;
→ x + 35 = 56 ;
Then, we SUBTRACT "35" (FROM EACH SIDE OF THE EQUATION) ; to isolate "x" on ONE SIDE OF THE EQUATION; and to solve for "x" ;
→ x + 35 − 35 = 56 <span>− 35 ;
</span>→ x = 21 .

Answer:
Step-by-step explanation:
Since the country wants to reduce the emission by the percentage each year, the function will be decaying function. The formula of decaying function will look like this
Where
E(t) = the number of emission after t years
E0= the number of initial emission= 40 million tons
r=rate of growth/decay = 35%= 0.35
t= time in years
If we put the number, the equation will be:
