6(-3-4y)
-18-24y
(Multiply 6 by both numbers)
Answer:
Medium: 4 and Large: 6
Step-by-step explanation:
Factor pairs that are equivalent to 10:
1,9
2,8
3,7
4,6
5,5
and so on. So you could do 2.4*9 and 1.8*1. If that doesn't work, switch it around. This coud probably take 1/2 of a hour or more. But it'll be worth it if it's a grade. :3
In the end, I'm pretty sure you should be able to get the answer:
Medium cups: 4
Large cups: 6
1.8 multiplied by 4 would get you 7.2 and 2.4 multiplied by 6 would get you 14.4. If you add them all up, you would get a 21.6! If you didn't, check your math again.
Answer:
$2.83
Step-by-step explanation:
Diameter of the pool = 24ft
Cost of 1 ft² = $0.15
Area of the pool=?
But the pool is a circular pool,
Area of a circle = Πr² or πd²/4
π = 3.142
Area of the pool = (π * 24) / 4
Area = (3.142 * 24) / 4
Area = 18.85ft²
If 1ft² = $0.15
18.85 = $x
x = (18.85 * 0.15) / 1
x = $2.8275 = $2.83
The cost of the pool is $2.83
Given that the number, 5,83_ has 2 as a factor.
It implies that the number 5,83_ is an even number
The number contains
5 thousands
8 hundreds
3 tens
? units
The possible units of an even number are 0, 2, 4, 6, and 8
Therefore, the unknown digit could be 0, 2, 4, 6, or 8
we are given
![f(x)=\frac{1}{9x-2}](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7B1%7D%7B9x-2%7D)
For finding inverse function , we do following steps
step-1:
Set f(x)=y
![y=\frac{1}{9x-2}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B9x-2%7D)
step-2:
Switch x and y
![x=\frac{1}{9y-2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B9y-2%7D)
step-3:
now, we can solve for y
![x=\frac{1}{9y-2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B9y-2%7D)
Multiply both sides by 9y-2
![x\times (9y-2)=(9y-2)\times \frac{1}{9y-2}](https://tex.z-dn.net/?f=x%5Ctimes%20%289y-2%29%3D%289y-2%29%5Ctimes%20%5Cfrac%7B1%7D%7B9y-2%7D)
![x(9y-2)=1](https://tex.z-dn.net/?f=x%289y-2%29%3D1)
![9xy-2x=1](https://tex.z-dn.net/?f=9xy-2x%3D1)
Add both sides by 2x
![9xy-2x+2x=2x+1](https://tex.z-dn.net/?f=9xy-2x%2B2x%3D2x%2B1)
![9xy=2x+1](https://tex.z-dn.net/?f=9xy%3D2x%2B1)
now, we can divide both sides by 9x
![y=\frac{2x+1}{9x}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2x%2B1%7D%7B9x%7D)
so, we get inverse function as
