Answer: I would say -8,-1
Step-by-step explanation:
Total charges from bank A exists $15.
Total charges on Bank B spending exists $45.
<h3>How to estimate the
Total charges on bank B?</h3>
Given: Bank A charges a $15 monthly fee for a checking account and debit card, with unlimited transactions.
Shade 25 transactions.
Total charges from bank A = $15 monthly
Bank B charged a $35 monthly fee for a checking account and debit card, plus $ 0.70 for each transaction.
She made 25 transactions.
Total charges on bank B = $35 + (0.40)25
Total charges on bank B = $35+10
Total charges on bank B = $45

I think al you have to do is 7x9 but im not sure dubble check it for me. haha
We have that
f(x) = x + 2 x − 6------------ > <span>f(x) = 3x− 6
</span>The function is continuous in the interval (-∞,∞)
<span>
y=3x-6--------- >3x=y+6------> x=(y+6)/3
</span>Interchange x and y<span> to find the inverse function
</span><span>(f −1)(x)=(x+6)/3----> (x/3)+2
</span>Apply derivative <span>with respect to x</span>
(f −1)'(x)=1/3
for all values of x (f −1)'(x)=1/3
therefore
for a=3 (f −1)'(a)=1/3
