What is the slope of a line perpendicular to 24x-9y=63

Mathematics

In order to find the slop it is probably best to put the equation in y=mx+b form. This means to get y by itself on one side. 
24x-9y=63 will then become -9y=63-24x in which y has been isolated.
Then you should divided by -9 to get the final form: y=24x/9 -63/9.
 Now you can get the slope of the perpendicular line by taking the slope of the original equation and finding its reciprocal which is -9/24x. This is your answer.

3yd 4yd what is the length of the hypotenuse
hjlf

Answer:

5 yd

Step-by-step explanation:

Use Pythagorean theorem,

Hypotenuse² = base² + altitude²

                      = 3² + 4²

                       = 9 + 16

                       = 25

Hypotenuse = √25 = √5*5 = 5 yd

What is the point-slope form of the equation of a line that passes through the point (1, 4) and has a slope of −3?
zmey [24]
So y=mx+b
m=slope

y=-3x+b
subsitutue 1 for x and 4 for  y
4=-3(1)+b
4=-3+b
add 3 to both sides
7=b

the equaiton is y=-3x+7

What is equivalent to 9 3/4?
Nata [24]

Step-by-step explanation:

We need to say that 9^{3/4} is equivalent to what.

We know that, (3)² = 9

So,

9^{3/4}=((3)^2)^{3/4}\\\\=3^{3/2}

We can write 3^{3/2} =3\times 3^{1/2}

And 3^{1/2}=\sqrt{3}

So,

3\times 3^{1/2}=3\sqrt{3}

So, 9^{3/4} is equivalent to 3\sqrt{3}.

Hence, this is the required solution.
