Answer:
or 
Step-by-step explanation:
we know that
The general equation of a horizontal parabola open to the left is equal to
where
(h,k) is the vertex of the parabola
p is the focal distance (distance from the vertex to the focus)
In this problem we have
The vertex is the point (2,-4)
so
The Focus is the point F(1,-4)
so
the focal distance p=2-1=1 ---> distance from the vertex to the focus
substitute in the formula
Answer:
27
Step-by-step explanation:
CDE is a right angle so the sum of CDF and FDE is equal to 90
2x + x + 9 = 90 add like terms
3x + 9 = 90 subtract 9 from both sides
3x = 81 divide both sides by 3
x = 27
Answer:
W = 3
Step-by-step explanation:
2(W - 1) + 8 = 6(2w - 4)
2w - 2 + 8 = 12w - 24
2w + 6 = 12w - 24
6 = 10w - 24
30 = 10w
3 = W
Hope this helps. Pls give brainliest.
4 will go into 25 six times
that leaves 1.20. 4 goes into 1.20 .3 times
6+.3 is 6.3
3x + 2y = 3. subtract 3x from both sides, so you get 2y = -3x + 3 . then you divide by 2 to both sides , so you get y = -3/2x + 3/2 .
