nect for up to (but not including) one minute. For each additional minute or part of a minute, there is a $0.24 cent charge. (For example, 1 minute up to but not including 2 minutes costs $0.63.) This fare is only valid for up to (but not including) 40 minutes. 
Express this information as a function, where f(x) represents the amount of money charged and x represents the number of minutes which have elapsed.

The area ( l x w ) of the postcard is 24 square inches. What is the width b of the message (in inches)?
pentagon [3]

area = (l)(w)(h)

24 = 4(3 + b)

24 = 12 + 4b

-12 on both sides

12 = 4b

/4 on both sides

b = 3 inches

Substitute b = 3 inches in width

3 + b

3 + 3 = 6 inches

Answer:

width = 6 inches

Evaluate the function. f(x) = 3x² – x Find f(10)​
kirill [66]

Answer:

<em>f(10)=290</em>

Step-by-step explanation:

<u>Function Evaluation</u>

Given a function f(x) as an explicit expression, finding f(x=a) implies substituting the value of x by a in every instance it occurs.

We are given the function:

f(x)=3x^2-x

It's required to find f(10). We replace the x for 10:

f(10)=3*10^2-10

Operating:

f(10)=3*100-10

f(10)=300-10

f(10)=290

Thus, f(10)=290

Solve for v 12v = 18+6v
jekas [21]

12v = 18+6v

move +6v to the other side

sign changes from +6v to -6v

12v-6v= 18+6v-6v

12v-6v= 18

6v= 18

divide by 6 to get v by itself

6v/6=18/6

Answer:

v= 3
