Hi there!
A horizontal line has no slope, or the slope of 0.
Since a horizontal line is just a straight line across a point, and it never has an x intercept, the slope is always either "no slope", 0, or undefined.
Hope this helps!
A negative number doesn't have a square root...
only one number has to be negative not both...
and 820 doesn't have a perfect square root...
it would be 28.635...
Answer:
2/5 =0.4
Step-by-step explanation:
Decimals are one of the method of representation of fractions in which there is power of 10 in the denominator of the fraction. They are 10,100,1000,10,000 ,100,0000 and so
Example = 1/10 = 0.1
1/100 = 0.01
1/1000 = 0.001
In 2/5 we have to make the denominator 10
since in denominator there is five , can be made 10 by multiplying it by 2
2/2 = 1 and 1* x = x , hence if we multiply numerator and denominator by 2 it won't change the fraction.
2/5×2/2=2×2/5×2=4/10=0.4
Thus, 2/5 =0.4 in decimal form.
