Answer: 11:50
Step-by-step explanation:
Ok, la manecilla de los minutos apunta al numero X.
si la ora es Y, entonces Y + X = 12:00
podemos asumir que Y es 11:y
y es la cantidad de minutos despues de las 11, es un numero entre 0 y 59 (por que una hora solo puede tener 60 minutos)
Si la manecilla de los minutos apunta al numero 6 por ejemplo, entoces:
y = 11:30 y X = 6 min
X + y = 11:30 + 0:06 = 11:36
Así funciona.
la equacion es:
y = 5*X
y tambien queremos que:
X + y = 60min
reemplazo y por lo de la equacion de arriba:
X + y = X + 5*X = 6X = 60min
X = 10
Si la manecilla apunta al 10, tenemos que:
y = 11:50 y X = 10min
y + X = 11:50 + 0:10 = 12:00
Entonces podemos concluir que la hora es 11:50.

each coin has a 1/3% chance of being picked
Step-by-step explanation:
Answer:
3x - 2y = 1
Step-by-step explanation:
Step 1: Find the slope
slope m = (y2 - y1)(/x2 - x1)
m = (4 - 1)/(3 - 1) = 3/2
Step 1: Use the formula y = mx + b to solve
This is slope-intercept form of a line. We have a slope of 3/2, and a point (x, y), which is (1, 1). Plug those values into the equation above and solve for b (the only variable we are missing
1 = (3/2)(1) + b
1 = 3/2 + b
1 - 3/2 = b
2/2 - 3/2 = b
-1/2 = b
Step 2: Rewrite the formula using the slope and the b value we just calculated
y = (3/2)x - 1/2
Step 3: Standard form of a line is ax + by = c, where a is a positive integer, so we rearrange the equation from step 2 to standard form.
y = (3/2)x - 1/2
-(3/2)x + y = -1/2 (subtract (3/2)x from both sides)
-3x + 2y = -1 (multiply by 2 to get rid of the fraction on x)
3x - 2y = 1 (multiply by -1 so a becomes positive)
Answer:
2) reflection in the line y = x
Step-by-step explanation:
A function is transformed to its inverse by swapping the independent and dependent variables. Reflection in the line y = x does that.
