Answer:
Option D that is y=-2(x+1) is the correct choice.
Explanation:
Given equation:
We have to find another equation which has only one solution.
Standard form of equation:
Condition for one solution.
We have to arrange other equation in the form of 
Mark all the options as a,b,c and d.
Now from the above options we can see that option 
are not providing the desired result.
So
can be obtained from the last option.
As
Option D that is 
is the equation from where we can obtained only one solution.
F - because you must move the decimal place 9 spaces to the left in order to have only a single digit in front of the decimal place. (There can never be more than one otherwise it is no longer scientific notation.
Answer:
Total cost for curtains = Rs.3,700
Step-by-step explanation:
Assume we have:
1 Door ( l = 8ft, b=4ft)
3 Windows (l = 4t, b = 3.5ft)
Curtains at the rate of Rs.50 per ft²
Find:
Total cost for curtains.
Computation:
Area of door = (8)(4)
Area of door = 32 ft²
Area of 3 windows = (3)(4)(3.5)
Area of 3 windows = 42 ft²
Total ares = Area of door + Area of 3 windows
Total ares = 32 ft² + 42 ft²
Total ares = 74 ft²
Total cost for curtains = Rs.50 × Total ares
Total cost for curtains = Rs.50 × 74 ft²
Total cost for curtains = Rs.3,700
Answer:
132,000
Step-by-step explanation:
so lets start with the yearly increase
we find this by doing 20,000*.28
which equals 5,600
next we need 20 years so we multiply by 20
5,600*20=112,000
don't forget we have to add the original population though
112,000+20,000=132,000
