Let's sin t= a, cos t =b and tan t=c. write the expression in terms of a, b and c. 9 cos (-t) -cos t

When you answer this can you explain

Write the slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7. t

What are the solutions of the equation? 6x^2 + 11x + 4 = 0 a. 4/3, 1/2 b. -4/3, -1/2 c. 4/3, -1/2 d. -4/3, 1/2
