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 $y=7$

In the past year Jenny watched 44 movies that she thought were very good. She watched 55 movies over the whole year. Of the movi

igomit [66]

To solve this problem, we must divide the number of movies that Jenny thought were very good by the total number of movies she watched. This is because we are finding a percentage, which represents a part out of a whole that have a factor, which in this case is very good movies. First, we begin by dividing 44/55. Then, we realize that both the numerator and the denominator are divisible by 11, so if we divided them both by 11 that would simplify the fraction.

44/55 = 44/11 / 55/11 = 4/5

Next, we can now easily divide our simplified fraction.

4/5 = 0.8

Finally, we must multiply by 100, because a percentage is a portion of 100 (the total is 100%). This is equivalent to moving the decimal point two places to the right.

0.8 * 100 = 80%

Therefore, Jenny thinks that 80% of the movies she watched this year were very good.

Hope this helps!

Answer:

Step-by-step explanation:

1.) y= 1/5x - 2

2.) y = 1x + 2

3.) y = 2x + 4

4.) y = 1x + 4

5.) y = 1/3x - 4

6.) y = 1/2x - 3
