F(0) =4 and f(2)=8 slope intercept form of the equation of the line

y=2x+4 or f(x)=2x+4

Step-by-step explanation:

f(0)=4 is (0,4) and f(2)=8 is (2,8)

first, find the slope using the equation y2-y1/x2-x1

8-4/2-0

4/2

2

now, take one of the points, and put it into the equation y2-y1=m(x-x1) (m is slope)

take (0,4) for example

y-4=2(x-0)

y-4=2x

y=2x+4

y=f(x)

so, substitute as

f(x)=2x+4

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
