Tnemos el sisema de ecuaciones:

Podemos resolverlo por eliminación sumando ambas ecuaciones y eliminando y. Asi podemos resolver para x:

Ahora podemos resolver para y con cualquiera de las dos ecuaciones:

Respuesta: x=-3, y=0
Answer:
-.6 repeating
Step-by-step explanation:
The slope of the line that passes through (5,−10) and ( 11 , − 12 ), in simplest form is: -1/3
<em><u>Recall:</u></em>
- The slope of a line passing across through two points can be calculated using:

<em><u>Given two points:</u></em>
(5,−10) and ( 11 , − 12 )


Slope (m) = -2/6
Slope (m) = -1/3
Therefore the slope of the line that passes through (5,−10) and ( 11 , − 12 ), in simplest form is: -1/3

Answer:
Shania has read the most pages.
Step-by-step explanation:
Following the formula y = mx + b.
Kevin already read 45 pages.
y = mx + 45
He reads 20 pages per hour, since it has per hour, we put it has "m"
y = 20x + 45
Shania already read 5 pages
y = mx + 5
Shania reads 25 pages per hour
y = 25x + 5
We need to find out how many pages they read after 20 hours, plug 20 into x.
Kevin
20(20) + 45 =
400 + 45 =
445
Shania
25(20) + 5 =
500 + 5 =
505
Shania read 60 more pages than Kevin.
