Answer:
8
Step-by-step explanation:
4+4=8
Answer:
7 > -7
Step-by-step explanation:
-9 is not greater than -4
-6 is not greater than -5
I am not sure what 7 -7 means in your first option but if it is consistent, then yes, 7 is greater than -7.
Step-by-step explanation:
Selling price = Rs.80
Cost price = Rs.100
here, CP > SP
Now...
Loss ( L ) = CP - SP
= RS.100 - 80
= Rs.20
Now...
= 20 %
Slope of the line = 
.
y-intercept of the line = -7.
Solution:
General form of equation of a line:
y = mx + c
where m is the slope and c is the y-intercept of the line.
Equation of a line:
To compare this with general equation.
Slope of the line = .
y-intercept of the line = -7.
M can be any positive real number.
Explanation:
From f(x) = √(mx) ; if x is posive m has to be positive; if x is negative m has to be negative; if x is cero m can have any value, and the range will always be 0 or positve
From g(x) = m √x; x can only be 0 or positive and the range will have the sign of m.
Given we concluded that the range of f(x) can only be 0 or positive, then me can only be 0 or positive.
