Answer:
The answer is B
Step-by-step explanation:
If 68 minutes ago it (then) was three times as many minutes past 10 am (now)
x + 68 = 3 ×
×
(120 - x) →
→
x = 73 min
… if 68 minutes ago it (now) was three times as many minutes past 10 am (then)
x = 3 ×
×
[120 - (x + 68)] →
→
x = 39 min
… if 68 minutes ago it (then) was three times as many minutes past 10 am (then)
x + 68 = 3 ×
×
[120 - (x + 68)] →
→
x = 22 min
The equation of the line in point-slope form is given by:

Where,
(xo, yo): point that belongs to the line
m: slope of the line
The slope is given by:

Substituting values:

Rewriting:

Now we choose an ordered pair:

Substituting values we have:

We now rewrite the equation in its standard form:

Where,
b: cut with the y axis.
We have then:
Answer: point-slope form: 
or
standard form
Answer:
La longitud = 7 metros
La anchor = 10.5 metros
Step-by-step explanation:
La fórmula para el perímetro de un rectángulo es
P = 2L + 2W
L = longitud
A = ancho
P = 35 metros
se sabe que el doble de su ancho es igual a 3 veces su largo.
2A = 3L
Ancho = 3L / 2 = 1.5L
Sustituimos 1.5L por W
35 = 2 L + 2 (1.5 L)
35 = 2L + 3L
35 = 5 litros
L = 35/5
L = 7 metros
Por lo tanto, la longitud = 7 metros
Recuerda
A = 1.5 L
A = 1.5 × 7
A = 10.5 metros
La anchor = 10.5 metros
