A van travels at a speed of 70kph. Calculate the mass of the sun???

Not really

•What are the roots of x²+5x+6=0 ?

Given the quadratic equation , you must factor it

So we have the factor of

Equate each to zero

So the roots are -2 and -3

Hope this helps =)

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
