Answer:
Step-by-step explanation:
Let the number of miles = x
C ost = Base + 0.84x
Cost = 220.71 dollars
Base = 19.95
220.71 = 19.95 + 0.84x Subtract 19.95 from both sides
220,71 - 19.95 = 0.84 x Combine
200.76 = 0.84x Divide by 0,84
200.76/0.84 = x
x = 239 miles.
Remark: The trick to this question is to make sure that total Cost, the Base amount, and cost / mile are all in dollars. Don't mix and match.
Hello,



==> 1+r=5==>r=4
3+3r+3r²+3r^3+...+3r^6=3(1+r+r²+...+r^6)=3*(r^7-1)/(r-1)=4^7-1=16383
The answer is 102
3x+2x+50=180
5x+50=180
5x+50-50=180-50
5x=130
5x/5=130/5
X=26
2(26)+50=102
is the algebraic representation for an exponential function
Step-by-step explanation:
Given:
f(x + 1) = 4.f(x)
f(3) = 16
To Find:
Algebraic representation for an exponential function=?
Solution:
From the formula f(x+n) =
f(x)
when n= 1, x= 3
f(3+1)= 4(1)f(3)
f(4)= 4f(3)
Substituting the value of f(3)
f(4)= 4f(3)
f(4)= 4 x 16
f(4)= 64
f(4)=
f (5) =
x 16
f (5) =
x
f(5)= 
Similarly,
F(6) = 
Hence, 
Answer:
the first answer
Step-by-step explanation:
1/8 of the absolute value is 1/8 positive
anything from the absolute value is positive because absolute value is the value of how far away the number is from zero.
