Answer:Redondeo al entero más cercano, ejemplos. Denotemos por ρ a la función de un argumento real que lo redondea un número real más cercano: ρ(7.394) = 8,.
Step-by-step explanation:
Answer:
What you want to do is divide the numbers.
Step-by-step explanation:
It can be done so in simple daily calculations such as calculating how much money you'll have after after you spend some.
<span>$100- $52= $48
and
if you switch it into an addition problem you will get
$100+(-52)= $48,
Or you can get $48 + $52 = $100</span>
Answer:
x = -3.5 or -1
Step-by-step explanation:
Add 7 and factor.
2x^2 +9x +7 = 0
(2x +7)(x +1) = 0
x = -3.5 or x = -1 . . . . . values that make the factors zero

<em>Comment on factoring</em>
Factoring ax^2 +bx +c = 0 requires you find factors of ac that have a sum of b. Here, you're looking for factors of 2·7 = 14 that have a sum of 9. If you're observant, you realize that 2+7=9, so 2 and 7 are the factors you want.
Now, you can write the factored form as ...
(ax +p)(ax +q)/a = 0 . . . . where p and q are the factors of ac we just found
The divisor "a" is used to simplify one or both of the factors. Here, we have ...
(2x +2)(2x +7)/2 = 0
(x +1)(2x +7) = 0 . . . . . . we removed a factor of 2 from the first binomial
Hope this is what’s you where looking for
