"For what value of x does g(x) = 0"
g(x) = y
This is asking:
when y = 0, what is the value of x?
Or you can see it as (?, 0)
6 is the value of x
-7 and 5
You can get this by factoring to the following
(x + 7)(x - 5)
Then set both equal to zero and solve individually.
Answer:
26 or 62
Step-by-step explanation:
If one of the two digits of a two-digit number is three times the other digit, then the options for the two-digit number are:
If you interchange the digits of this two-digit number and add the resulting number to the original number, you get 88.
From inspection of the listed pairs of numbers, the only pair that sums to 88 is 26 and 62:
⇒ 26 + 62 = 88
Therefore, the original number is either 26 or 62.
