Step-by-step explanation:
Answer:
40 and 20
Step-by-step explanation:
- Uncle Jason's age = x
- Nephew Ralph age = y
<h3>Solution</h3>
<u>Age now:</u>
<u>Age 10 years ago: </u>
<u>Substituting x in the second equation:</u>
- 2y - 10 = 3y - 30
- 3y - 2y = 30 -10
- y = 20
<u>Then, finding x:</u>
<u>Answer:</u> Uncle Jason is 40 and nephew Ralph is 20 years old

Answer:
1. k=0
2. yes, result is still a polynomial.
3. yes, f and g must have the same degree to have deg(f+g) < deg(f) or deg(g)
Step-by-step explanation:
1. for what constant k must f(k) always equal the constant term of f(x) for any polynomial f(x)
for k=0 any polynomial f(x) will reduce f(k) to the constant term.
2. If we multiply a polynomial by a constant, is the result a polynomial?
Yes, If we multiply a polynomial by a constant, the result is always a polynomial.
3. if deg(f+g) is less than both deg f and deg g, then must f and g have the same degree?
Yes.
If
deg(f+g) < deg(f) and
deg(f+g) < deg(g)
then it means that the two leading terms cancel out, which can happen only if f and g have the same degree.
