2. x = 6
Answer:
True
Step-by-step explanation:
A matrix needs to be in a same size
In order to be increased, decreased, etc
So it is true
It won't be false trust me ;)
I hope this helps you :)
Answer:
A) ![E(w)=450+0.10w](https://tex.z-dn.net/?f=E%28w%29%3D450%2B0.10w)
B) $1200
Step-by-step explanation:
Let w represent employee's weekly sales and
be total weekly earnings.
We have been given that a phone store employee earns a salary of $450 per week plus 10% commission on her weekly sales.
A) The total weekly earnings of employee would be weekly salary plus 10% of weekly sales.
10% of weekly sales, w, would be ![\frac{10}{100}*w=0.10w](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B100%7D%2Aw%3D0.10w)
![E(w)=450+0.10w](https://tex.z-dn.net/?f=E%28w%29%3D450%2B0.10w)
Therefore, the function
models the employee's weekly earnings.
B) To find the weekly sales in the week, when employee earned $570, we will substitute
in our formula and solve for w as:
![570=450+0.10w](https://tex.z-dn.net/?f=570%3D450%2B0.10w)
![570-450=450-450+0.10w](https://tex.z-dn.net/?f=570-450%3D450-450%2B0.10w)
![120=0.10w](https://tex.z-dn.net/?f=120%3D0.10w)
![0.10w=120](https://tex.z-dn.net/?f=0.10w%3D120)
![\frac{0.10w}{0.10}=\frac{120}{0.10}](https://tex.z-dn.net/?f=%5Cfrac%7B0.10w%7D%7B0.10%7D%3D%5Cfrac%7B120%7D%7B0.10%7D)
![x=1200](https://tex.z-dn.net/?f=x%3D1200)
Therefore, the amount of employee's weekly sales was $1200.
Answer:
f(x) = 1.2x
Step-by-step explanation:
Given:
f(x - 5) = 1.2x - 6
Required:
Find f(x)
To solve f(x), we have to express f(x - 5) in terms of f(x).
This is done as follows
f(x - 5) = 1.2x - 6
Factorize the expression at the right hand side
f(x - 5) = 1.2(x - 5)
Now we can solve for f(x) by substituting x for x - 5 in the above expression (on the right hand side and the left hand side)
f(x) = 1.2x
Hence, if f(x - 5) = 1.2x - 6 then f(x) = 1.2x
