I think that it should be a because you don't have real property
The first one you have
=
. To solve this you would multiply both sides by 3.
=x
Then simplify by dividing the numerator and denominator by 3.
=x (or in a mixed fraction 1
)
The second one you have
=
. To solve this you would multiply both sides by x.
x=3
Now you would divide both sides by
.
x=
You now then multiply 3 by 24 and then divide by 7.

x=
(in a mixed fraction would be 10
)
Answer:
If you mean only one rational solution, the answer is

If you mean at least 1 rational solution, the answer is
![k\in (-\infty, -8]\cup[8, \infty)](https://tex.z-dn.net/?f=k%5Cin%20%28-%5Cinfty%2C%20-8%5D%5Ccup%5B8%2C%20%5Cinfty%29)
Step-by-step explanation:

Let's calculate the discriminant.



Now, remember that:



Therefore, I will just consider the first two cases.

and





The answer would be 2,4,6,8,10
Answer:
a) 45 g
b) greater (make the graph youself on desmos or something)
c) 9/4
Step-by-step explanation:
area = integral 0 to 3 of x^2 dx = [1/3x^3] 0 to 3 = 9
mass = density * area = 5 * 9 = 45 grams
area = y*deltax = x^2*deltax
x = integral 0 to 3 of 5x^3 dx / mass = (405/4) / 45 = 9/4
