What number is represented by point P?
likoan [24]

Answer:

0.0057

Step-by-step explanation:

  • Narrow it down.
  • The point P is between 5 * 10^-3 and and 6*10^-3
  • When you go to the bottom line, P is on the 7th division from the left.
  • Going from left to right increases P
  • P is on a line that goes between 5 and 6. Each division is 1/10. So P is in the tenth place.
  • One of the answers is 5.7 * 10^-3
  • The other answer is .0057
  • I really don't know which one to choose because we are given no direction. As a programmer, 0.0057 would be easier to program. I would choose it.
  • If it is not correct, then 5.7 * 10^-3 is the answer.

Please help<br><br>problem 1, 2 and 3​
laila [671]

Answer:

See attached

Step-by-step explanation:

When there is a lot of repetitive calculation to do, I like to let a spreadsheet or graphing calculator do it. The attached shows a spreadsheet that computes all the values you're asked to find.

For a linear equation in standard form, ax +by = c

  • the x-intercept is: c/a
  • the y-intercept is: c/b
  • the slope is: m = -a/b

Of course, the slope-intercept form of the equation is ...

  y = (slope)·x + (y-intercept)

and the values of the various points on the graph can be computed from that equation.

___

You will note that the last two equations describe the same line.

_____

<em>Note on spreadsheet formulas</em>

When you put the formulas into the spreadsheet, make sure to fix the column number or row number of the values you're computing, as appropriate. For example, the y-values in the different columns always use the slope from the slope column (fixed), the y-intercept from that column (fixed), and the x-value from the top row (fixed). If you make the cell references relative instead of fixed, you will get wrong answers.

Help please!!!!!!!!!<br> A. (1, -2)<br> B. (1, 2)<br> C. (2, -1)<br> D. Infinite number of solutions
Maru [420]

Answer:

(1, -2)  Option A in your list of possible answers

See attached image.

Step-by-step explanation:

We need to graph the lines by using a couple of points on the plane for each equation.

For example:

the points (0, -3)  and (3, 0) for the line  y = x - 3

and the points (0, 1) and (-1, 4) for the line  y = - 3 x + 1

Please see the lines in the attached image, and notice that they intersect at the point (1, -2), which gives you the solution for the system.
