What is the equation, in slope-intercept form, of each line? a. parallel to y = 3x + 1 through (4, −1) b. perpendicular to y = 3x − 4 with the same y-intercept as −x + 5y = 10

Suppose that x and y are both differentiable functions of t and are related by the given equation. use implicit differentiation with respect to t to determine startfraction dy over dt endfraction in terms of x, y, and startfraction dx over dt endfraction .

Enter the number of complex zeros for the polynomial function in the box. f(x) = x+ + 5x² +6

Researchers were interested in whether relaxation training decreases the number of headaches a person experiences. they randomly assigned 20 participants to a control group or a relaxation training group and noted the change in number of headaches each group reported from the week before training to the week after training. which statistical analysis should be performed to answer the researchers' question?
