It is biased because they surveyed people who were at a park, therefore they enjoy parks and would want more in the area

If the interest paid was $1428 on a principal of $5100 and an interest rate of 4%, how many years was the loan for?

Vaselesa [24]

Answer:

7 years

Convert 4% to a decimal. 4% = 0.04

1428 = 5100(.04)t

1428 = 204t

1428/204 = 204t/204

t = 7 years

Answer:

The result for an input of 7 is: $y=15$

The output (y-value) associated with an input of 3 is: $y=7$

Step-by-step explanation:

The image attached shown the graph for the rule $y= 2x+1$ .

In order to use the graph to predict the result for an input value of 7, you need to follow these steps:

- Draw a vertical line from $x=7$

- When the vertical line touches the graph, you must draw a horizontal line to the y-axis to find the y-value.

You can observe in the graph that the result for an input value of $x=7$ is $y=15$

Follow these steps in order to use the graph to predict the output value associated with an input value of 3:

- Draw a vertical line from $x=3$

- When the vertical line touches the graph, you must draw a horizontal line to the y-axis to find the y-value.

You can observe in the graph that the output value associated with an input value of $x=3$ is $y=7$
