Factorise completely<br>x²-7x=12​
Rashid [163]

Answer:

undefined

Step-by-step explanation:

x²-7x=12

we make the equation equal to zero by subtracting 12 from both sides, we have..

x²-7x-12 = 12-12

x²-7x-12= 0

we find the factors of 12 such that when we multiply them we will get -12 and when we add them we will get -7, and those factors are but those values are not possible..

so answer = undefined

3y &lt;= -2x+18
weeeeeb [17]

Answer:

  • A (-4, -3)
  • C (2, 4)
  • E (3, 2)

Step-by-step explanation:

It is convenient to use technology to plot the points and the functions to see what lies where. The first attachment shows such a plot.

_____

Of course, you can do the function evaluations. For example, testing answer B, we find ...

... 3·6 ≤ -2·1 +18 . . . . <em>false</em> for the first equation — not a solution

Checking all the points requires 10 function evaluations. When things get repetitive like that, I like to use a graphing calculator or spreadsheet.

_____

<em>Using a calculator</em>

The second attachment shows a calculator evaluating the viability of each point as a solution. The equations have been rearranged to ...

  • -2x -3y +18 ≥ 0
  • -x +4y +12 ≥ 0

This makes it easy to look at the evaluation results to see if the solution is viable or not.

The x-values of the points are entered into list L₁ and the y-values into L₂. The result of the first inequality above is in L₃ and the result for the second inequality is in L₄. Any negative value in L₃ or L₄ shows a point that is <u>not</u> part of the solution set. Points B and D fail to match problem requirements.

Points A, C, and E are in the solution set.
