Answer:
Step-by-step explanation:
Equation of line is y = mx + b
m is the slope = -2
b is the y intercept = -1
:- y = -2x - 1
The sqrt function has the distributive property.
So sqrt(a/b) = sqrt(a) / sqrt(b).
In this case, a = 81, and b = 625.
sqrt(81) = 9.
sqrt(625) = 25.
So sqrt(81/625) = 9 / 25.
To get a decimal representation, multiply by a form of 1 that makes the denominator a power of 10. Here, 25 * 4 = 100, so
9/25 * 4/4 = 36/100 = 0.36
First you multiply 9*4=36 then multiply 36*3/2=108/2
Then multiply 1/2 * 1/2 *1/2 =1/8
Lastly divide 108/2 and 1/8
which is 108/2*8/1 =864/2=432
So the answer is 432. Hope this helps
