Answer:
Cosθ= -√2/3
Sinθ= -√7/3
tanβ= 4/3
Sinβ= 4/5
Cosβ= 3/5
sin(θ+β) = sin(θ)cos(β)+cos(θ)sin(β)
(-√7/3)(3/5) + (-√2/3)(4/5)
-√7/5 - 4√2/15
The answer to 82.2% of 50 is 41.1

Answer:
c. x = 7-t; y = -1/(t -7)
Step-by-step explanation:
To find the parametric equation for x, use the equation for t and solve for x.
t = 7-x
x = 7 -t . . . . . . add x-t to both sides
__
To find the parametric equation for y, substitute the equation for x.
y = 1/x
y = 1/(7-t)
To make this match the available choices, we need to multiply numerator and denominator by -1.
y = -1/(t -7)
The parametric equations are ...
x = 7 -t; y = -1/(t -7) . . . . . . matches choice C
Answer:
The two lines meet at (-1,1)
(2x^3-6x-4)/x if your simplifying that's the answer
