Answer:
Step-by-step explanation:
first find the slope
m = Δy/Δx = (-1 - (- 5)) / (4 - (-2)) = 4/6 = 2/3
Then plug either point into the equation
y - y₁ = m(x - x₁)
y + 1 = 2/3(x - 4)
which is equivalent to
y + 5 = 2/3(x + 2)
Answer:
x + a + 2
Step-by-step explanation:
g(a) = a² + 2a
g(x) - g(a) = x² + 2x - a² - 2a
= x² - a² + 2x - 2a
= (x - a)(x + a) + 2(x - a)
= (x - a)(x + a + 2)
[g(x) - g(a)] ÷ (x - a)
= x + a + 2
Answer:
La función es: f(x) = 20+0.5x
Step-by-step explanation:
La función que representa la condición sería:
f(x) = 20+0.5x
Donde:
- 20 € es el costo por día
- x es la cantidad de kilómetros
- f(x) cobro por dia en función de los kilómetros

Answer:
C. $14.95
Step-by-step explanation:
Do $13 times 15 divided by 100 and add that to $13.
4^2 = 16
16 x 2 = 32
32, Hope this helps!
