First, find the least common denominator (LCD) of the two denominators.
12: 12, 24, 36
36: 36
The LCD is 36.
Second, make the denominators the same as the LCD. / Your problem should look like:
+
Third, simplify. The denominators are the same now. / Your problem should look like:
+
Fourth, join the denominators. / Your problem should look like:
Fifth, simplify. / Your problem should look like:
Sixth, simplify. / Your problem should look like:
Answer as fraction:
Answer as decimal: 0.4444
Answer:
8 units
Step-by-step explanation:
ratios
(x-3) /( x+1) = (x-2)/(x+3) cross multiply
x^2 -x -2 = x^2 - 9
-x - 2 + 9 = 0
x = 7
so TS = x + 1 = 8 units
Answer:
Step-by-step explanation:
Given : focus of (1, -3) and a directrix of y= -1
The distance between focus and directrix is 2p
The distance between (1,-3) and y=-1 is 2
So 2p = 2 and p =1
Vertex (h,k) lies inbetween the focus and directrix
focus is (h, k-p)
given focus is (1,-3)
so h=1 and k-p = -3 ( we got p =1)
So k-1= -3 , k= -2
Hence, vertex is (1,-2), h=1 and k = -2
Here focus at the bottom and directrix at the top
so parabola opens down
hence a= -1/4
Plug it in the equation
