1.) Distribute the negative to what is in the parenthesis
2x - 3 + x > x + 1
1.) Simplify
Distribute the negative to what is in the parenthesis:
2x - 3 + x > x + 1
Solve for x
3x - 3 > x + 1
2x - 3 > 1
2x > 4
X > 2
2.) We know that x is everything thing greater than 2. The answer would be D because the highlighted part (x) is everything that is greater than 2
Parameterize this surface (call it ) by
with and . The limits on should be obvious. We find the upper limit for by solving for where the sphere and cone intersect:
Take the normal vector to to be
(orientation does not matter here)
Then the area of is
Answer:
e.29 d.1
Step-by-step explanation:
we will replace with the values we have :
- 300 that's a big number . Obviously it isn't a solution
- 50 : 30+50 = 80>60 so no
- 45: 30+45= 75 >60 so no
- 30+30 = 60 we have < not ≤ so no
- 1 yes . it's obvious
- 29 +30 = 59<60 so yes !
F,d,c don’t make it harder then it has to be
Let S(n) the statement, 2 is a factor of .
For n=1, 1^2 + 7(1) = 1 + 7 = 8, 1 is a factor of 8, then S(1) is true.
For n=2, we have 2^2 +7(2) = 4 +14 = 18, of course, 2 is a factor of 18, then S(2) is true.
For n=3, we have 3^2 +7(3) = 9 +21 = 30, of course, 2 is a factor of 30, then S(3) is true.
