Answer:
The format of the equation of a line is y=mx+c so in order to know whether which line is perpendicular to line y=5x-9, gradient of y=5x-9,which is 5,has to multiply by another gradient to get -1.[in short m1×m2=-1]
So the equation perpendicular to line y=5x-9 has a gradient of -1÷5=-1/5
Answer:
the last option, 10,12,15
Step-by-step explanation:
for every 3 of something you have 5 of something else, so the ratio is 3:5. That means when you have 6, double the amount of 3, you have the double amount of 5, 10.
The radical is 3sqrt(x^18)
18/2=9
so, the radical is
3x^9
