Answer:
B
Step-by-step explanation:
(x,y) = P + (a)t
(x,y) = (4,7) + t(3,8)
(x,y) - (4,7) = t(3,8)
(x-4, y-7) = t(3,8)

2) AB=AC/2=16/2=8;
Answer:
4
Step-by-step explanation:
to solve | a | - | b | + | c | we need to plug in the given values
a = -8
b = -5
c = 1
the | | bars mean absolute value which is the exact value a number is away from 0 on a number line. an absolute value has to be positive, not a negative, as you cant be negative spaces away from something. plugging in the values into the equation we have:
| -8 | - | -5 | + | 1 |
the absolute value of -8 is 8, as -8 is 8 units away from 0 on a number line
like wise with -5, the absolute value of -5 is 5, as -5 is 5 units away from 0 on a number line
1 is the absolute value of 1 as its 1 unit away from 0 on a number line
the new expression looks like the following:
8 - 5 + 1
now we just add/subtract
8 -5 = 3
3 + 1 = 4
the solution to this expression is 4
Answer:
Las opciones no se pueden ver, así que responderé de una forma general.
Primero rompamos la frase en partes más cortas
"cuatro veces un número..."
Esto se escribe como 4*N, donde N es el número.
"... la suma de dos
números"
Esto se escribe como K + M
donde K y M son dos números, entonces K + M es la suma de dos números.
Entonces:
"cuatro veces un número dividido por la suma de dos
números"
Se escribirá como:
(4*N)/(K + M )
