As for square roots, a number r is a square root of a number x if r^2 = x. Based on this definition, a positive number actually has two square roots: a positive number and the negative of that positive number. For example, the numbers 5 and -5 are square roots of 25 because 5^2 = 25 and (-5)^2 = 25

If a varies directly as b, and a = 28 when b = 7, find b when a = 5.
Reika [66]

Answer: Option B.

b=\frac{5}{4}

Step-by-step explanation:

If a varies directly with b then when a increases b it also increases by a factor k.

Then we can write that

a = kb

We know that when a = 28 then b = 7. So

28 = k * 7

k=\frac{28}{7}

k=4

Therefore the equation of proportionality is:

a=4b

So when a=5  then:

5=4b\\\\b=\frac{5}{4}
