Answer: Yes, it is correct
Step-by-step explanation: Because of that, When you multiply 4.2 x 3 x 4 = 50.4
16-12+12x17= 208 u should use a calcuator
Answer:
![y = 9.6x](https://tex.z-dn.net/?f=%20y%20%3D%209.6x)
Yes, y is a function of x.
![x = \frac{5}{48} y](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B5%7D%7B48%7D%20y)
Step-by-step explanation:
For a proportional relation, the equation is given by:
![y = kx](https://tex.z-dn.net/?f=y%20%3D%20kx)
where k is the unit rate of change.
We were told that, Lin's sister earns $9.6 per hour.
This means k=9.6.
We substitute to get:
![y = 9.6x](https://tex.z-dn.net/?f=y%20%3D%209.6x)
We could rewrite this as
![y(x) = 9.6x](https://tex.z-dn.net/?f=y%28x%29%20%3D%209.6x)
Yes, y is a function of x.
To obtain an equation describing x as a function of y, we solve for x to get:
![x = \frac{1}{9.6} y](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B1%7D%7B9.6%7D%20y)
About 11% - I first subtracted 250 from 282, to get 32. I then did 32/282 to get .11.... You round that out to about 11%
Answer: 3, 6, 9, 12
Step-by-step explanation:
A geometric progression has a common ratio.
2,6, 18 and 54 has a common ratio of 3. When you multiply the first number by 3, you get the second number and the same thing applies to the third number.
1, 5, 25 and 125 has a common ratio of 5. When you multiply the first number by 5, you get the second number and the same thing applies to the third number.
4, 8, 16 and 32 has a common ratio of 2. When you multiply the first number by 2, you get the second number and the same thing applies to the third number.
3, 6, 9 and 12 is an arithmetic progression as 3 is added to each number
