Jim is ranked third best in his class of 50 students.
The sum of the measures of the angles of a polygon of n sides is 180(n - 2).
Set that expression equal to 1800 and solve for n, the number of sides.
180(n - 2) = 1800
Divide both sides by 180
n - 2 = 10
Add 2 to both sides
n = 12
The polygon has 10 sides.
Answer:
Two solutions: -0.12 and 1.75.
Step-by-step explanation:
The quadratic formula is:
. Assuming that the x² term is a, the x term is b, and the constant is c, we can plug the values into the equation.

Answer:
B. & E.
Step-by-step explanation:
First, to find your slope, put your line into slope-intercept form.


Your slope is
.
Now, you can find the y-intercept of your parallel line by plugging your given point and your slope into point-slope form.

Your y-intercept is 1.
If you notice, answer choice E is equivalent to one of our steps in converting it to point-slope form. Therefore, E is one of your answers.
The equation of your parallel line is:

B is also a correct answer.
If you put B into slope-intercept form, you get the following:

This, of course, is equivalent to the parallel line which we already found, so we know it is parallel.
