Answer:
No real roots.
Step-by-step explanation:
Unless you guys are dealing with imaginary numbers, you cannot take the square root of a negative.
The answer is neither; you only have to substitute the ordered pair on the equation y=7x-2; ordered pair (a,b).Substitution: b=7a-2.
Answer:
y =
Step-by-step explanation:
since y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
to find k use the given condition y = 9 when x = 72
k = = = , hence
y = × x =

Total money= 85
Total ratio=3+2=5
A=3/5 x 85/1
=85 divided by 5=17 x 3=51 euroes
