The sum of two consecutive even integers is 266. what is the lager integer?

134

Step-by-step explanation:

Integers are whole numbers that can be positive or negative.  If an integer and the next even integer are added together, we can assign them variables:

first integer: x

second even integer: x + 2

Since the sum is equal to 266:

x + x + 2 = 266

combine like terms: 2x + 2 = 266

subtract 2 from each side: 2x + 2 - 2 = 266 - 2 or 2x = 264

divide by 2: 2x/2 = 264/2 or x = 132

second even integer: 132 + 2 = 134

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

answer: 12,000
