Step-by-step explanation:
A decimal is a number that represents a fractional part of a whole. For example, the decimal 0.25 represents 25/100. Numbers with decimals are not integers because an integer is defined as a whole number with no fractional part.
The linear equation that models the value of the investment in the year x is y = 574x + 2700
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let y be the value of the investment in the year x, where x = 0 represents 1992
An investment is worth $2700 in 1992 (x = 0). By 1997 (x = 5) it has grown to $5570, hence:
y - 2700 = [(5570 - 2700)/(5 - 0)](x - 0)
y = 574x + 2700
The linear equation that models the value of the investment in the year x is y = 574x + 2700

Well if its exponential it must be x ^n
Answer: 29/28
Step-by-step explanation:
To add fractions we have to calculate the Least Common Denominator of the denominators. Then we have to change each fraction (using equivalent fractions) to make their denominators the same as the Least Common Denominator. Then we can add (or subtract) the fractions.
LCD (4,7,2)= 4·7 = 28
1/4 = 7/28
2/7 = 4·2/28 = 8/28
1/2 = 14/28
Since the fractions have the same denominator we can add them
7/28 + 8/28 + 14/28 = (7+8+14)/28 = 29/28
