What is a way to write 100,000 using exponents?
Helen [10]
ANSWER

100,000=10^5
EXPLANATION

We want to write 100,000 using exponents.

This means that, we want to write 100,000 as an index number, that is a certain number raised to a certain index or exponent.


The exponent tells us how many times that number multiplies itself to give 100,000

100,000=10 \times 10 \times 10 \times 10 \times 10

Since 10 multiplies itself 5 times to give 100,000, we write

100,000=10^5

How many ways can David pick four of the first twelve positive integers such that no two of the numbers he picks are consecutive
vekshin1

Answer:

70 times

Step-by-step explanation:

5 consecutive even integers: 2n, 2n+2, 2n+4, 2n+6, 2n+8 for any integer n The sum of the two smallest of five consecutive even integers is 50 less than the sum of the other three integers: 2n + 2n+2 = 2n+4 + 2n+6 + 2n+8 - 504n + 2 = 6n -3234 = 2nn = 17 The smallest integer in our sequence is 2n = 2*17 = 34 Check:2n + 2n+2 = 2n+4 + 2n+6 + 2n+8 - 5034 + 36 = 38 + 40 + 42 - 5070 = 120 - 5070 = 70

Which of the options represents the resulting equation after an equivalent expression for y is substituted into the second equat
Nina [5.8K]

Answer:

Correct choice is D

Step-by-step explanation:

Given the system of two equations:

\left\{\begin{array}{l}4x+y=8\\6x-9y=12\end{array}\right..

Fro mthe first equation

y=8-4x.

Substitute into the second equation 8-4x instead of y:

6x-9(8-4x)=12.

Note that 8-4x=-4x+8, then the second equation will take look

6x-9(-4x+8)=12.
