18 because they need to be identical and you only have 18 chocolate bars
The coefficient is the number in front of the variable. If there isn't a number, it is understood to be a 1
The domain of the function given above is the value of w that would make it reasonable. Among the numbers, w cannot be zero because that would make the fraction 70/0 undefined. So the domain of the function is from negative infinity to positive infinity but not zero.
Answer:23,000 or twenty-three thousand
Olá boa tarde meu nome é "Guilherme" sou de Brasil e vou resolver a sua pergunta
a ) 2x - 2y = 12
{ a 2
{ b 2
{ c 12
<u>/</u><u>\</u> = b elevado 2 -4 a.c
<u>/</u><u>\</u> = (2) elevado 2 -4 . 24
<u>/</u><u>\</u> = 4 -4 . 24
<u>/</u><u>\</u> = 24
X = <u>-</u><u>b</u><u>+</u><u>/</u><u> </u><u>/</u><u>\</u><u> </u> = <u> </u><u>2</u><u> </u><u>-</u><u> </u><u>5</u>

S = {20,10}
b) 29. - 3y = -2
{ a = 29
{ b = -3
{ c = -2
<u>/</u><u>\</u> = b elevado 2 -4 a.c
<u>/</u><u>\</u> = (-6) -4 . 58
