Joe is researching the cost of going to college. he sees the table shown.

joe wants to create a mathematical model, f(x), where x represents the number of academic years since 1979-1980, to predict future cost of tuition and fees using data in the table.

which type of function will most closely match the data?
a) decreasing linear function
b) increasing linear function
c) exponential decay function
d) exponential growth function

D) exponential growth function

Step-by-step explanation:

i dont know sorry

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
