When it is raining outside, you tend to stay in and watch TV. The number of hours of TV that you watch in a given week is twice the number of rainy days in that week. In the equation below, y is the number of hours of TV you watch in a week, and x is the number of rainy days in that week.
The relationship between these two variables can be expressed by the following equation:
y=2xy=2xy, equals, 2, x
Identify the dependent and independent variables.

Express the following as a function of a single angle, cos(60) cos(-20) - sin(60) sin(-20)

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.

Create and solve a linear equation that represents the model, where squares and triangles are shown evenly balanced on a balance beam. assume the weight of a square is 1 unit and the weight of a triangle is unknown.
