Answer:

x = -1 or 2

Step-by-step explanation:

Taking the antilog, you have the quadratic ...

x^2 -x -1 = 1

x^2 -x -2 = 0 . . . . subtract 1

(x -2)(x +1) = 0 . . . factor

The values of x that make these factors zero are the solutions to the equation.

How do i use Scientific notation on these problems? Because I don't know...

saveliy_v [14]

Answer:

Simplify the problems first

Step-by-step explanation:

Before you can convert it to scientific notation, you should simplify it first.

#1 for example:

$(4 \times 10^5)^2\\$

Use PEMDAS to solve the equation:

$(4 \times 10^5)^2\\= 400000^2\\= 160000000000$

So, now we have a super big number. To write it in scientific notation, put a decimal place in the number before the zeroes start. It would be $1.6 \times 10^{11}$ since there are 11 places after the decimal.

the answer would be 33. so the first thing you want to do is turn 7 feet into inches. if 12 inches is equal to 1 foot then 7 feet are equal to 84 inches. then add another 84 inches which will equal 168. the you would want to divide 168/15 which gives you 33.6. this mean that 33 (separate numbers) 15 inches of board from two boards.

hope I was able to help and that my explanation made sense. : )

Step-by-step explanation:

$\huge{\purple{\underline{\underline{\bf{\pink{Answer}}}}}}$

Firstly we have to take variables to L.H.S and numbers to R.H.S

$13n + 5n = - 8 + 16 \\ 18n = 8 \\ n = \frac{8}{18} \\ n = \frac{4}{9}$

Hope it helps

The value of y varies directly with x.

Usimov [2.4K]

Answer:

Step-by-step explanation:

Hello. Y/x = a constant k because y and x are by definition always in the same ratio. (y varies directly as x so if x is doubled y is also doubled etc.)
