Taylor states that 2,800,000 in scientific notation is 2.8 x 10 -6 because the number has six places to the right of the 2. Is T
soldier1979 [14.2K]

Scientific Notation is the way of <u>writing a number or expressing them</u> in a <u>shorter or more compact way.</u>

No, <u>Taylor's resoning is incorrect</u> because  2,800,000 = 2.8  * 10^{6}

From the question, we are given:

2,800,000 .

2,800,000 in scientific notation is  2.8  * 10^{6}.  

The reason the power is not to the negative 6 is that we are moving from the right-hand side to the left-hand side 6 times.

Therefore, <u>Taylor's reasoning is incorrect. </u>

Y = 3/2x + 5/4 −2x + 8y = −25
Andreyy89

Answer:

<h2>x = -347 1/2</h2>

Step-by-step explanation:

When solving algebra, it is important the we follow the steps in correct order and check our answer at the end.

Step 1: Simplify by combining like terms

y = -x/2 + 5/4 + 8y = -25

Step 2: Substitute

y = -25

-25 = -x/2 + 5/4 + 8(-25)

-25 = -x/2 + 5/4 + -200

-25 = -x/2 - 198 3/4

Step 3: Answer

x = -347 1/2

Step 4: Check

y = 3/2x + 5/4 −2x + 8y = −25

-25 = 3/2(-347 1/2) + 5/4 −2(-347 1/2) + 8(-25)

-25 = -25✔️

Step 5: Verified Answer

x = -347 1/2

I'm always happy to help :)
