Add subtraction multiplication and division

If you want to multiply fractions just multiply across for example 1/2 times 1/2
1x1=1
2x2= 4
The answer would be 1/4
For division it’s very similar
For example 1/1 divided by 1/2
Switch the sign divide by x
1/1 x 1/2
Then switch the second numbers numerator and denominator
1/1 x 2/1
=2/1

K = {(-3, -3), (-4, -4), (-5, -5), (-6, -6)} Is K a function and why? No, there is a limited number of ordered pairs in this lis
marysya [2.9K]

Answer:

Yes, no two ordered pairs in this list has the same second element.

Step-by-step explanation:

The function is a relation that associates to different elements x_1 and x_2 different elements y_1 and y_2.

Given K = {(-3, -3), (-4, -4), (-5, -5), (-6, -6)}

So,

  • x_1=-3\rightarrow y_1=-3;
  • x_2=-4\rightarrow y_2=-4;
  • x_3=-5\rightarrow y_3=-5;
  • x_4=-6\rightarrow y_4=-6.

Since different x have different image points y, this relation is the function. The correct answer is "Yes, no two ordered pairs in this list has the same second element."

How do you find the area of the field in <br> terms of x
Alex_Xolod [135]

Hello from MrBillDoesMath!


Answer:  104x^2 + 166x + 66

Discussion:

The area of a rectangle is given by "length" * "width". For us the formula becomes

 (13x + 11) * (8x+6)


or

13x (8x +6) + 11 * (8x + 6)  =


(13x * 8x + 13x* 6) + ( 11*8x + 11*6) =

(104x^2 + 78x ) + (88x + 66) =

104x^2 + (78x + 88x) + 66 =


104x^2 + 166x + 66


Thank you,

MrB
