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
262,144,000,000 is your answer to your question
<span>f(x)=3x−1
</span><span>domain is {-1, 0, 1}
3(-1) -1 = -4
3(0) - 1 = -1
3(1) - 1 = 2
Range { -4, -1, 2}</span>
(5x-7)2 + 140x
= 25x2 - 70x + 14 + 140x
= 25x2 + 70x + 14
= (5x+7)2
C let me know if I’m wrong
