Need derivative by using appropriate rules
5) y=3x^(5/4)
6)y=5/4x^2/3
7) y= -4x^-5
8) y=3/x^3

To be parallel, the slopes must be the same. To be perpendicular, the slopes must be opposite reciprocals (flip the fraction and multiply be -1)..

The slope of y = -3x/4 + 4 is -3/4

So C and D are correct for the first half..

The opposite reciprocal of -3/4 is 4/3, so D is the correct answer.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof
