Answer:
(- 4, 27 )
Step-by-step explanation:
Equate the right sides of both equations, that is
x² - 2x + 3 = - 2x + 19 ← subtract - 2x + 19 from both sides
x² - 16 = 0 ← in standard form
(x - 4)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 4 = 0 ⇒ x = - 4
Substitute these values into f(x) = - 2x + 19
f(4) = - 2(4) + 19 = - 8 + 19 = 11 ⇒ (4, 11 )
f(- 4) = - 2(- 4) + 19 = 8 + 19 = 27 ⇒ (- 4, 27 )

Using the law of sins:
X/ sin(44) = 4510/sin(180-44-36)
x / sin(44) = 4510 / sin(100)
x = 3,181 yards.
(-4, 2), (-1, 2), and (-4, 0
Answer:
solution
x<2,2x<-4,x-2<-4 are equvalent
but x-2<4 is not
