Jack and susie want to save to buy a trampoline for their children. they each open a savings account that earns 1.5% a
year. jack opens his account with $1,000, and susie opens her account with $800.
x = number of years
the following functions represent the value of the savings accounts in x years
jack's savings account: f(x) = 1000(1.015)*
susie's savings account: g(x) = 800(1.015)
which function represents the total amount jack and susie will save in x years?
200(1.015)
1800(1.015)
1800(1.015)2
1800(1.030)

Step-by-step explanation:

we have

we know that

To find the function that represent the total amount Jack and Suzie will save in x years, adds f(x) and g(x)

so

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
