In order to find the slope, you have to use the formula : Δy/Δx.
Here : Δy = -1 and Δx = 2.
Therefore, the slope would be : B. -1/2.
Hope this helps !

The amount invested by Mr.Smith in 5% is $240 .
<u>Step-by-step explanation:</u>
We have , Mr. Smith invests a certain amount of money at 8% and twice as much at 5%. If his annual income from the two investments is $720 . Let us suppose that Mr.Smith invest $x so :
Amount of money invested in 5% is
. And, amount of money invested in 8% is twice that of 5% i.e.
.
Now, total investment is $720 so,
+(
) = $720
⇒ ![\frac{5x}{100} + \frac{10x}{100} = 720](https://tex.z-dn.net/?f=%5Cfrac%7B5x%7D%7B100%7D%20%20%2B%20%5Cfrac%7B10x%7D%7B100%7D%20%20%3D%20720)
⇒ ![\frac{15x}{100} = 720](https://tex.z-dn.net/?f=%5Cfrac%7B15x%7D%7B100%7D%20%20%20%20%3D%20720)
⇒ ![\frac{100(720)}{15} = x](https://tex.z-dn.net/?f=%5Cfrac%7B100%28720%29%7D%7B15%7D%20%20%20%20%3D%20x)
⇒ ![x = 4800](https://tex.z-dn.net/?f=x%20%3D%204800)
The amount invested by Mr.Smith in 5% is
i.e.
. ∴ The amount invested by Mr.Smith in 5% is $240 .
Answer:
Step-by-step explanation:
The computation of the volume of the cylinder is shown below:
As we know that
The Volume of the cylinder is
= base × height
= (4x)^2 + (5x)^2
=16x^2 + 25x^2
= 41x^3
Hence, the volume of the cylinder is 41x^3
