Set up the following equations:
![x + y = 40](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%2040)
![20x + 18y = 770](https://tex.z-dn.net/?f=20x%20%2B%2018y%20%3D%20770)
x is the amount of hours worked on the weekday job, and y is the amount of hours worked on the weekend job.
We'll use substitution to remove one of the variables.
Multiply the first equation by -18 to get opposite coefficients for y:
![-18x - 18y = -720 ](https://tex.z-dn.net/?f=-18x%20-%2018y%20%3D%20-720%0A)
![20x + 18y = 770](https://tex.z-dn.net/?f=20x%20%2B%2018y%20%3D%20770)
Combine these two equations together:
![2x = 50](https://tex.z-dn.net/?f=2x%20%3D%2050)
Divide both sides by 2 to get x by itself:
![x = 25](https://tex.z-dn.net/?f=x%20%3D%2025)
Plug in x to the first original equation:
![25 + y = 40](https://tex.z-dn.net/?f=25%20%2B%20y%20%3D%2040)
Subtract 25 from both sides to get y by itself:
![y = 15](https://tex.z-dn.net/?f=y%20%3D%2015)
He worked
25 hours at his weekday job, and 15 hours at his weekend job.

Step-by-step explanation:
Dada la siguiente información:
Costo total= $1,956
<u>Para calculate el valor parcial, debemos usar la siguiente información:</u>
Precio proporcional= costo total* ( 1 - porcentaje de descuento)
50%:
Precio proporcional= 1,956*(1 - 0.5)
Precio proporcional= $978
25%:
Precio proporcional= 1,956*(1 - 0.75)
Precio proporcional= $489
The average low temperature would be 5+8+6+5+10+7+1 all divided by 7, so the answer is 6° celsius.

Answer:
h(x) = 2x²+2
Step-by-step explanation:
Given the function g is defined as follows.
g(x) = 2x²+7
If the graph is translated by 5units vertically downwards, this means that the function will be reduced by 5 units to have;
h(x) = 2x²+7 - 5
h(x) = 2x²+2
