Answer:
B.
Step-by-step explanation:
if x is 3 then you just substitue every instance of x as 3. 2(x-4) + 3x - x^2 =
2(3 - 4) + 3(3) - 3^2 =
6-8 + 9 - 9 =
-2

Answer:
x = 1 , y = 7
Step-by-step explanation:
R = 2 / (1 + sin <span>θ)
Using the following relations:
R = sqrt (x^2 + y^2)
sin </span>θ = y/R
<span>
R = 2 / (1 + y/R)
R</span>(1 + y/R<span>) = 2
</span><span>R + y = 2
R = 2 - y
sqrt(x^2 + y^2) = 2 - y
Squaring both sides:
x^2 + y^2 = (2 - y)^2
x^2 + y^2 = 4 - 4y + y^2
x^2 + 4y - 4
</span>
