The sum of three consecutive integers is 765. What equation describes the statement ?
1 answer:
Answer:
Step-by-step explanation:
The consecutive numbers are the numbers which come one after another .
Using Algebraic expressions
Let x be the first number , then the second number would be x+1 and the third number would be x+2.
The given statement : The sum of three consecutive integers is 765.
According to this statement , the equation will become :
Therefore, the equation that describes the statement would be :

x = 7 and x = –7.
Solution:
Given data:
and
To find the solutions when f(x) = 64.
Both are equations of f(x), so equate the given equations, we get
To isolate the constant term subtract 15 from both sides.
49 can be written as 7².
Taking square root on both sides of the equation, we get
x = ±7
The solutions to f(x) = 64 is x = 7 and x = –7.
Therefore, set y = 7
Solve for x
