A student’s work is shown below. y – 12.7 = 32.75

y – 12.7 – 12.7 = 32.75 – 12.7

y = 20.05

Which is the best statement about the student’s work?

The student solved the problem incorrectly. The student should divide both sides of the equation by -12.7 to create a zero pair.
The student solved the problem incorrectly. The student subtracted incorrectly because 32.75 – 12.7 is 20.68.
The student solved the problem incorrectly. The student should add 12.7 to both sides of the equation to isolate the variable, y.
The student solved the problem correctly. Subtracting 12.7 from both sides of the equation isolates the variable, y.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
