How to write .0000321 in scientific notation?
liberstina [14]
Scientific notation that's involved with numbers less than one, should always be counted from left to right. Count starting from the decimal until the first number you "jump over". What are you counting exactly?- the number of digits between the decimal and the first 'number' other than zero.

0.0000321 can be also written as 3.21*10^-5 (or 10 with a negative 5 exponent)
Hope this helps.

Y=-2x+4 y=6x+12 substitution method
sergey [27]

Answer:

x = - 1, y = 6

Step-by-step explanation:

Given the 2 equations

y = - 2x + 4 → (1)

y = 6x + 12 → (2)

Substitute y = 6x + 12 into (1)

6x + 12 = - 2x + 4 ( add 2x to both sides )

8x + 12 = 4 ( subtract 12 from both sides )

8x = - 8 ( divide both sides by 8 )

x = - 1

Substitute x = - 1 into either of the 2 equations and solve for y

Substituting into (2)

y = 6(- 1) + 12 = - 6 + 12 = 6

Solution is (- 1, 6 )

Step-by-step explanation:

The margin of error in a confidence interval is half the range:

(84 - 76) / 2 = 4

Please help on this. I am confused.
neonofarm [45]
The answer is 2x^2-3x-2.

To solve this, you take f(x)-g(x) which is 2x^2-5-3x+3. This simplifies to 2x^2-3x-2.
