Y=40x + 225
Because x is your per hour cost.
Answer:
The solution is (-2, 0)
Step-by-step explanation:
Re-write -2x=-y+4 x=-2 in column form:
x=-2
-2x=-y+4
Next, substitute -2 for x in the second equation:
-2(-2) = -y + 4, or:
4 = -y + 4. Thus, y must be 0.
The solution is (-2, 0)
Answer:
= $ (x + 145 + 145)
= $ (x + 290)
So in this way end of every week her salary will increase by $ 145.
Step-by-step explanation:
Answer:
The maximum of y = sin x is 1. The amplitude of a sinusoidal function is one-half of the positive difference between the maximum and minimum values of a function.
Step-by-step explanation:
Answer:
Point (1,8)
Step-by-step explanation:
We will use segment formula to find the coordinates of point that will partition our line segment PQ in a ratio 3:1.
When a point divides any segment internally in the ratio m:n, the formula is:
![[x=\frac{mx_2+nx_1}{m+n},y= \frac{my_2+ny_1}{m+n}]](https://tex.z-dn.net/?f=%5Bx%3D%5Cfrac%7Bmx_2%2Bnx_1%7D%7Bm%2Bn%7D%2Cy%3D%20%5Cfrac%7Bmy_2%2Bny_1%7D%7Bm%2Bn%7D%5D)
Let us substitute coordinates of point P and Q as:
,
![y_1=-4](https://tex.z-dn.net/?f=y_1%3D-4)
![x_2=4](https://tex.z-dn.net/?f=x_2%3D4)
![y_2=12](https://tex.z-dn.net/?f=y_2%3D12)
![m=3](https://tex.z-dn.net/?f=m%3D3)
![[x=\frac{4}{4},y=\frac{32}{4}]](https://tex.z-dn.net/?f=%5Bx%3D%5Cfrac%7B4%7D%7B4%7D%2Cy%3D%5Cfrac%7B32%7D%7B4%7D%5D)
Therefore, point (1,8) will partition the directed line segment PQ in a ratio 3:1.
