1 Subtract <span>11</span> from both sides
<span>y-1={3}^{x}<span>y−1=<span>3<span><span>x</span><span></span></span></span></span></span>
2 Use Definition of Common Logarithm: <span>{b}^{a}=x<span><span>b<span><span>a</span><span></span></span></span>=x</span></span> if and only if <span>log_b(x)=a<span>lo<span>g<span><span>b</span><span></span></span></span>(x)=a</span></span>
<span>\log_{3}{(y-1)}=x<span><span><span>log</span><span><span>3</span><span></span></span></span><span>(y−1)</span>=x</span></span>
3 Switch sides
<span><span>x=\log_{3}{(y-1)}<span>x=<span><span>log</span><span><span>3</span><span></span></span></span><span>(y−1)

Answer:
c=37
Step-by-step explanation:
.35x+45=y
x is the miles they run
.35 shows that they charge 35 cents per mile
45 is the constant or the fee they always charge to use their vehicle
I can't really graph this for you but here's some points.
(X, Y): (-4, 0), (-3, 3), (-2, 0), (-1, -3), (0,0)
Here's the end behavior:
x⇒∞, y⇒∞
x⇒-∞, y⇒-∞
