(Disregard the pi, Multiply the radius and height)
9 × 9 × 12
81 × 12
972
972π sq. units
Answer:
the answer is 6 ___________________________
Point-slope form is:
y - y1 = m (x - x1)
So the correct form for that equation would be:
y - 4 = 3 (x - 2)
So the correct equation is the first one.
Answer:
the answer is (-4, 5)
Step-by-step explanation:
Let's use elimination by addition / subtraction:
-6x - 2y = 14
6x + 7y = 11
-------------------
5y = 25, so y = 5.
Substituting 5 for y in the 2nd equation, we get:
6x + 7(5) = 11, or:
6x + 35 = 11, or
6x = -24, or x = -4.
Thus, the answer is (-4, 5). Please double check to ensure you have copied down both system of equations and answer correctly.
Check: Is (-4, 5) a solution to this system?
Subst. -4 for x and 5 for y in the first equation:
-3(-4) - (5) = 7
12 - 5 = 7 YES
Answer:
Points of intersection should be included within the feasible region (the solution set) of a system of nonlinear inequalities when the boundary lines that create the point are solid. A dashed line indicates that the points are not included in the solution set. Therefore, if one boundary line is dashed and one is solid, the point of intersection will not be included within the feasible region.
