Answer:
Step-by-step explanation:
We can directly substitute y of the first equation to the second equation.
-2x - 1 = 3x - 16
5x = 15
x = 3
Substituting back to any of the two equations, we get y = -2(3)-1 = -7. If you check with the second equation, y = 3(3)-16 = -7 as well.
Therefore .
Answer: C
Step-by-step explanation:
To find the surface area of a cone, you use the formula . Since we are already given the height and radius, all we have to do is plug in the values and solve.
[solve inside of square root]
[parenthesis]
[multiply]
Therefore, the closest answer is C.
Substituting into point-slope form,
