Put the terms in order of decreasing degree, all on the left. When convenient, it is nice to have mutually prime integer coefficients with the leading one positive.

a) x² -2x +1 = 0

b) x² +15 = 0

c) 4x² -12 = 0
or, better, divide out the common factor of 4.
  x² -3 = 0

d) 3x² -x -5 = 0

_____
Shown is the standard form for a single-variable second-degree equation. Form varies depending on the nature of the equation. Equations of conic sections have different standard forms, depending on the curve.

A linear function has the same y-PLEASE PLEASE HELP!!!!intercept as x+2y=10 and it’s graph contains the point (9,7) find the slo
Anastasy [175]

Answer:

I think it is 2/9 or 0.22

Step-by-step explanation:

You know they have the same y intercept, so first you should find the y intercept of the givern equation.

<em>x+2y = 10   </em>

<em>2y = -x + 10        [subtract x]</em>

<em>y = -.5x + 5          [divide by 2]</em>

Now you have the equation in graph form, and know the y intercept is 5.

If the unknown function has the same y intercept, you know it contains the point (0,5), and it is given that it includes the point (9,7)

now that you have two points, you can use slope formula.

<em>(y2 - y1)/(x2-x1)</em>

<em>(change in y)/(change in x)</em>

so,

<em>(7-5)/(9-0) = 2/9 = 0.2</em>

someone please correct me if i'm wrong:)

Chien always works 20 hours/week at $15/hour and gets paid every 2 weeks.
Leto [7]

Answer:

  • $600
  • net pay
  • taxes, insurance, retirement plan contributions
  • net pay

Step-by-step explanation:

The gross pay that shows up on your paycheck is the sum of wages, commissions, and any other earnings your employer may share with you (tips, insurance offsets, bonuses). From this gross pay, government regulations may require the deduction of taxes of various kinds. Your employer may deduct the cost of insurance, and you may voluntarily have amounts deducted for additional taxes, insurance, union dues, or retirement plan contributions. The pay that you take home is the net pay after these deductions.

__

Chien gets paid at the rate of $15 per hour for 20 hours per week and 2 weeks per pay-period. We are not told of any other earnings or contributions to his gross pay. So, it will be ...

  ($15/h)(20 h/wk)(2 wk/period) = $600/period

Chien's gross pay will be $600 each pay period.

__

As discussed above, "net pay" and "take-home pay" are synonymous.

__

As discussed above, there may be a variety of deductions from his gross pay that will reduce his net pay. Often the largest of these is income tax together with Social Security tax. There may be additional deductions for insurance, union dues, health plan contributions, and retirement plan contributions.

__

Chien's budget should be based on money he <em>actually has available to spend</em>. That would generally be his net pay.

If Chien is considering changing jobs or his family situation, changes to payroll deductions may figure into his budget. Ordinarily, those costs would be considered "fixed" and not subject to a budgeting process.
