Answer:
a. y = 0
b. x = 0
c. y = x
d. y = -x
Step-by-step explanation:
a. Since it is a horizontal line, its gradient does not change so its gradient shall remain as 0. Thus, y = 0x which is basically y = 0.
b. Since it is a vertical line, it is impossible to define its gradient or y-intercept but its x-intercept would always be at 0 so x = 0.
c. Since it is a line that is gradually getting higher across the x-axis, its gradient would be 1. It's y-intercept is 0 so the equation of this line would be y = 1x + 0, which is basically y = x. (We don't write 1x, but rather just x, putting zeros behind an equation is redundant)
d. Since it is a line that is gradually getting lower across the x-axis, its gradient would be -1. It's y-intercept is also 0 so the equation of this line would be y = -1x + 0, which is basically y = -x ((We don't write -1x, but rather just -x, putting zeros behind an equation is redundant)
El dominio de la sucesión aritmética generada por s(n) = 7 + 3 · n es n ≥ 1.
<h3>¿Cuál es el dominio de la sucesión aritmética?</h3>
En este problema tenemos que David derivó una formula para generar los elementos de la sucesión aritmética s(n) = 7 + 3 · n, cuyo dominio es el conjunto de elementos de números naturales n tal que los elementos de la sucesión aritmética son generados.
Se puede apreciar que el dominio está constituido por un conjunto discreto y semi-infinito, esto es, un conjunto de números naturales que tiene un valor mínimo, más no un valor máximo. Es preciso determinar el valor más pequeño de n tal que s(n) = 10:
7 + 3 · n = 10
3 · n = 10 - 7
3 · n = 3
n = 1
En consecuencia, la expresión dada tiene un dominio consistente en todo número natural n tal que n ≥ 1.

Answer:
CT=37
Step-by-step explanation:
5x-3 = 2x+21
-2x
3x-3 = 21
+3
3x = 24
÷3
× = 8
5(8) - 3 = 37
2(8) +21 =37
I think it would be 11 because if it was 12 hours it would been way more then $1265. they are asking you for hours not minutes. I am pretty sure it would be 11. I hope this helped!
