2.4 because 4.8/2 is 2.4. 14.4/4 is also 2.4. Constant of variation is the unit rate
71 is the answer. If you round it, it would be 70.
When simplifying this, we would have to take this little by little in serious steps and not only this, but to also take notice of the use of <u>
pemdas</u>
and to make sure that we take each step carefully.
We first would <u>

simplify the following:
We know that
a1=1
a2=3
a3=9
a2/a1=3/1----> 3
a3/a2=9/3----> 3
<span>common ration r is equal to 3
number of terms n is 12
The </span><span>Sum of geometric series is given by the formula
</span>Sum=a1*[1-r<span>^n]/[1-r]
</span>Sum=1*[1-3^12]/[1-3]-----> Sum=[1-3^12]/[1-3]----> [3^12-1]/[3-1]
<span>Sum=531440/2-----> 265720
the answer is
265720

I hope this helps
3x-y=13
step 1: add y to both sides
3x-y+Y=13+Y
3x=y+13
step 2: divide both sides by 3
3x/ 3 = y+13/3
x=1/3y+ 13/3
answer: x=1/3y+13/3
