x < 243
Step-by-step explanation:
Answer:
f(x)=-x+3
Step-by-step explanation:
contains (0, 3) and (3, 0)
slope = (3-0)/(0-3)=3/-3=-1
f(x)=-x+b
b=3
f(x)=-x+3
Answer:
Solution : Option C
Step-by-step explanation:
We have the equations r² = x² + y², x = r cos(θ), and y = r sin(θ) that can be used to solve this problem. In this case we only need the second two equations ( x = r cos(θ), and y = r sin(θ) ) as we don't need to apply the concept of circles etc here.
Given : x = - 9,
( Substitute r cos(θ) for x )
r cos(θ) = - 9,
r = - 9 / cos(θ)
( Remember that sec is the reciprocal of cos(θ). Substitute sec for 1 / cos(θ) )
r = - 9 sec(θ)
Therefore the third option is the correct solution.
Since ur using r as a variable the answer is r = 7.
Answer:
9/4
Step-by-step explanation:
y2 - y1 / x2 - x1 = 6 - (-3) / 2 - (-2) = 9/4
