the slope of (-2,4) and (3,0) is -4/5
Step-by-step explanation:
Answer:
y = ![\frac{49}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B49%7D%7B3%7D)
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 7 when x = 3
k =
=
, thus
y =
x ← equation of variation
When x = 7, then
y =
× 7 = ![\frac{49}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B49%7D%7B3%7D)
Answer:
V=16
Step-by-step explanation:
We are given that an inverse variation
![p=\frac{8}{V}](https://tex.z-dn.net/?f=p%3D%5Cfrac%7B8%7D%7BV%7D)
We have to find the value of V when p=1/2
To find the value of V we will substitute the value of p
Substitute the value of p
Then, we get
![\frac{1}{2}=\frac{8}{V}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B8%7D%7BV%7D)
![\frac{V}{2}=8](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7B2%7D%3D8)
Using multiplication property of equality
![V=8\times 2](https://tex.z-dn.net/?f=V%3D8%5Ctimes%202)
Using multiplication property of equality
![V=16](https://tex.z-dn.net/?f=V%3D16)
Hence, the value of V=16
Answer:
11
Step-by-step explanation:
it says motor cycles combined with garbage so add both of them then subtract that from the bull dosers
motor =18
garbage=4
18+4=22
bulldosers=11
22-11= 11 more
