The term that has a degree of 8 is -2x³y⁵
<h3>How to find the degree of a polynomial?</h3>The polynomial above is a monomial. A monomial is a polynomial with a single term.
Therefore, the degree of a monomial is the sum of the exponents of all its variables.
In other words, a monomial is a number, a variable or a product of a number and a variable where all exponents are whole numbers.
Hence, the term with degree of 8 is -2x³y⁵
Degree = 0 + 3 + 5 = 8

Answer:
see below
Step-by-step explanation:
A graphing calculator shows each of the lines intersect the circle in exactly one place, so is tangent.
__
Each of the given lines is written in point-slope form. Each has a slope of 1/3. We will call the point in its equation the "reference point" of each line. For the first line, it is (6, -15); for the second line it is (-2, 9).
The center of the circle is (2, -3), so the slope from the center to the reference point of each line is ...
line 1: (-15 -(-3))/(6 -2) = -12/4 = -3
line 2: (9 -(-3))/(-2-2) = 12/-4 = -3
These slopes are the negative reciprocal of the slope of each of the lines, so a segment from the circle center to the reference point of each line is perpendicular to the line.
__
The reference point of line 1 (6, -15) is on the circle:
(6 -2)^2 +(-15 +3)^2 = 16 +144 = 160
The reference point of line 2 (-2, 9) is on the circle:
(-2-2)^2 +(9 +3)^2 = 16 +144 = 160
So, the reference point of each line is on the circle and that point is the endpoint of a segment from the circle center that is perpendicular to the line. Hence each of the lines is a tangent at its reference point.
