Andrew decided so joys a tenner clench. Below is a chart that displays how many games of lenis he has played and the meatal cost of playing those panes. In this scenario, C ( y ) represents the total cost for playing games.
The linear function that represents the situation is of:
C(y) = 13y + 145.
The intercept is of:
C(0) = 145, meaning that the flat fee to pay the game is of $145.
What is the linear function?The slope-intercept representation of a linear function is given by the rule presented as follows:
y = mx + b
The coefficients of the function and their meaning are listed as follows:
m is the slope of the function, representing the rate of change of the function.b is the y-intercept of the function, representing the initial value of the function.Two points of the function, from the table, are given as follows:
(8, 249) and (13,314).
The slope is given by the change in y of the two points divided by the change in x, hence:
m = (314 - 249)/(13 - 8) = 13.
Hence:
C(y) = 13y + b
When y = 8, C(y) = 249, hence the intercept b of the function is obtained as follows:
249 = 13(8) + b
b = 249 - 13 x 8
b = 145.
Meaning that the flat fee to pay the game is of $145.

“Benjamin Franklin was born in Milk Street, Boston, on January 6, 1706. His father, Josiah Franklin, was a tallow chandler [candle maker] who married twice, and of his seventeen children Benjamin was the youngest son. His schooling ended at ten, and at twelve he was bound apprentice to his brother James, a printer, who published the ‘New England Courant.’ To this journal he became a contributor, and later was for a time its nominal editor. But the brothers quarreled, and Benjamin ran away, going first to New York, and thence to Philadelphia, where he arrived in October, 1723.”

Write an equation that represents the line. Use exact numbers.
Answer:
[tex]y=-\dfrac{1}{3}x+5[/tex]
Step-by-step explanation:
A line's slope is defined as rise over run.
The rise and run between the coordinates (0, 5) and (3, 4) is:
rise: -1
run: 3
Therefore, the slope of the line is -1/3. This is what x is multiplied by.
Next, to find what is added to x, find where the line crosses the y-axis. IN this case, that point is when y = 5, so in the second blank put 5.

Step-by-step explanation:
En una expresión algebraica la reducción de términos semejantes se da entre los términos de igual variable o incógnita y exponente.
Por ejemplo:
3x² + 5x²
se pueden reducir pues tienen la misma variable x y el mismo exponente 2, su resultado se genera solo sumando, restando, los coeficientes, en este caso 3 y 5
3x² + 5x² = 8x²
En el caso:
3y² + 5x²
No se puede reducir pues la variable o incógnita no son iguales:
x≠y
En el caso:
3x² + 5x³
No se pueden reducir pues su exponente no es igual.
