6 trips because 1 trip = 3 km
If you divide 18 / 3 it would be 6 and by that multiply the # of trips.

What is an algebra?​
Angelina_Jolie [31]
In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics. It includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields.

What is the average rate of change of the function f(x)=20(14)xf(x)=20(14)x from x = 1 to x = 2? Enter your answer, as a decimal
Advocard [28]
The average rate of a function f(x) over an interval x = a and x = b is given by:

Average \ Rate \ of \ Change= \frac{f(b)-f(a)}{b-a}

Given the function

f(x)=20(14)^x

The average rate of change from x = 1 to x = 2 is given by:

\frac{f(2)-f(1)}{2-1} = \frac{20(14)^2-20(14)^1}{1}  \\  \\ =20(196-14)=20(182)=3,640

So totally confused please help
OLga [1]

Answer:

The answer to your question is: r = 0.1

Step-by-step explanation:

Data

P = $4500

A = $9000

t = 9 years

r = rate

Formula

                            r = \sqrt[t]{\frac{A}{P}} - 1\\

Substitution

                             r = \sqrt[9]{\frac{9000}{4500} - 1\\

Simplification

                             r = \sqrt[9]{2} - 1

Result

                             r = 1.08 - 1

                             r = 0.08 ≈ 0.1

y-intercept=3

y=.25x+3

Step-by-step explanation:

slope=rise over run so

slope=1/4

y-intercept is the value of y where the line crosses the y axis..

y-intercept=3

In y=mx+b form m is slope and b is y-intercept so...

y=.25x+3
