Answer:
A
Step-by-step explanation:
In the equation you have to replace all x's with -1
f (-1) = (-1)^2 - 8(-1) +5
f (-1) = 1 + 8 + 5
f (-1) = 14
the f(-1) stand for the function of -1. it is also equivalent to y
Responder:
(14 + 5) - (6 x 2)
Explicación paso a paso:
Para la operación dada:
14 + 5-6 x 2
Siguiendo la prioridad de operación matemática BODMAS.
Multiplicamos antes de realizar la suma:
-6 * 2 = 12
Ahora;
14 + 5 - 12
19 - 12 = 7
Por tanto, comprobamos cuál de las opciones nos da 7
(14 + 5-6) x 2
13 * 2 = 26
(14 + 5) - (6 x 2)
19 - 12 = 7
Por lo tanto, esto (14 + 5) - (6 x 2) da el resultado correcto
Answer:
Step-by-step explanation:
im guessing this is a system of equations so:
-7-y=13
8x+y=-14
so you can cancel them, out by adding
after you do the math you should get x=-1
substitute for y and you get y=-6
