Answer:
1 solution.
Step-by-step explanation:
-3d + 6 = 10
⇒ -3d = 10-6
⇒ -3d = 4
⇒ d = 
so, d = 
Answer:
Negative
Step-by-step explanation:less than
Let's solve by eliminating
x
. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.
Add the two equations.
Divide by -11 to isolate
y
y= -2
Substitute
y
=
−
2
into either of the 2 equations, I'll just use the second one.
x = -1
Using implicit differentiation, it is found that the rate of change of the surface area of the sphere -2201.293 square centimeters per second.
<h3>What is the volume of a sphere?</h3>
- The volume of a sphere, of radius r, is given by:

<h3>What is the surface area of a sphere?</h3>
- The surface area of a sphere, of radius r, is given by:

<h3>What is the rate of change?</h3>
Applying <em>implicit differentiation</em>, the rate of change of both the volume and the surface area can be found, as follows:


Volume of 3131 cubic centimeters, hence:



![r = \sqrt[3]{\frac{3(3131)}{4\pi}}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B3%283131%29%7D%7B4%5Cpi%7D%7D)

The volume of a sphere is decreasing at a constant rate of 9988 cubic centimeters per minute, hence:




Then, the <u>rate of change of the surface area</u> of the sphere is given by:

The rate of change of the surface area of the sphere -2201.293 square centimeters per second.

<span>(3a^2 - 2a + 4) - (a^2 - 3a + 7) = (distribute the negative sign)
3a^2 - 2a +4 - a^2 + 3a - 7 = (add like terms)
2a^2 + a - 3
So, the answer is A!
