Answer:
Step-by-step explanation:
The standard equation of a parabola is
y² = 4ax
where, a is the focus,
The coordinates of the centre of parabola is (0,0)
coordinates of focus is (a, 0)
It is symmteric about the x axis
the equation of directrix is x = -a.
Answer: x = 14 - 5y
y = 14/5 - x/5( if you solve for y )
2nd one x = 35/4 + y/4
y = -35 +4x ( solve for y )

Answer:
(d) -11
Step-by-step explanation:
Each of the functions is evaluated in the usual way: put the number where the variable is in the expression and simplify.
h(-1) = -2(-1)² -3(-1) +1 = -2 +3 +1 = 2
f(2) = (2(2) +7)/(2 -3) = 11/-1 = -11
Then f(h(-1)) is ...
f(h(-1)) = f(2) = -11
Answer:
600 calories
Step-by-step explanation:
120 (# of minutes in 2 hours) divided by 40 is 3, so multiply 200 by 3 and you get 600
