Answer:
Step-by-step explanation:
The given Equation is
.................(i)
Adding ( 
) on both sides of (i)
solving and cancelling out the terms will give
⇒ 
⇒ 
...................(ii)
Now we Know that
Applying this on equation (ii)
This will lead us to
Either 2x-3 =0 .......(iii) or 2x+3=0 ..........(iv)
Solving equation (iii) for value of x
2x - 3 =0
adding 3 on both sides
2x -3 +3 = 0+ 3
2x = 3
Cross multiplying gives
Solving equation (iv) for value of x
2x + 3 =0
adding -3 on both sides
2x -3 +3 = 0- 3
2x = -3
Cross multiplying gives
so and
Answer:
12
Step-by-step explanation:
80-56=24
16/8=2
24/2=12
Answer:
The ratio means that for every 8 fries, there is a ketchup. So if there were 16 fries, then there are 2 ketchup.
To solve this problem you must apply the proccedure shown below:
1. You have the following equation of a parabola, given in the problem above:
x<span>=1/16y^2
2. Then, based on the graph attached, you have:
p=y^2/4x
p=8^2/(4)(4)
p=64/16
p=4
3. The directrix is:
directrix=h-p
directrix=0-4
directrix=-4
The answer is:-4</span>
