8 0

Answer:

-5

Step-by-step explanation:

The given system is

x + 2y = 5 \\ x - 3y = 7

The corresponding coefficient matrix is shown in attachment.

The value of the system determinant, is the determinant of the coefficient matrix.

Which is

- 3 \times 1 - 2 \times 1 =  - 5

Which number is equal to the expression 7 x 104 + 3 x 103 + 0 x 102 + 8 x 101 + 5 ?
suter [353]

Answer:

1

Step-by-step explanation:

Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work?

We can think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term).

Here are some examples of scientific notation

6. Which ordered pairs are solutions to the inequality 5 − ≤20 Select each correct answer
dexar [7]
For questions #6 & #8, you didn't complete them or provide all necessary things (such as description, data, or graph). 5 − ≤ 20 is not an inequality, an inequality should be something like 5 - x ≤ 20, but you didn't give anything like that in your question.

7. (-1,4), (5,2), we can calculate the slope. As x increases from -1 to 5, (increases by 6), the y-value decreases by 2. -2/6 = -1/3, the slope is -1/3. The slope is negative and the y-value decreases by a third of the amount the x-value changes.
9. C, because you can only hold at MOST 500, and larger watermelons is represented by 10x. I'm assuming you made an error in your question, you gave me the values of larger/smaller watermelons only, and your question asked for larger & medium and the options seem to suggest there's only larger/smaller. 10x + 3y <= 500 or <, smaller than or equal would be the better choice if available.
10. y = 2x + 10, because 2 is the slope as minutes increase by 1, inches increase by 2, and the 10 inches of sawdust are already there.

When you offer Questions #6 & #8's data, I'll gladly help you with it. The rest of the questions are correct and properly explained.

Round 3424 to the thousands place
Masja [62]
To solve this...

Look at the number and determine how far it is from 3,000 and 4,000

Since 424 is closer to 0

And not 500... (which rounds up)

Your answer is going to be 3,000

Hope this was helpful.
