Aliyah wants to estimate the value of the quotient of 5 88% 10% and 854 x 10-, Which statement about the value is true? The value will be greater than 1 because (-3) -(-9) is a positive number. A number in scientific notation with a positive

exponent has a value greater than 1.

The value will be greater than 1 because (-3) -(-9)- 8. A number in scientific notation with a positive exponent is greater

than 1.

The value will be less than 1 because 5 88-8 54 is less than 1. The negative exponents will make it even smaller,

The number will be less than 1 because 5 88 x 10-> is a very small number and division always makes the size of a number

smaller

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

answer: your correct answer is b. d.

step-by-step explanation:

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
