1) y=-x+4, the slope is -1
2)y=-x+4, slope is -1
3) yes
4)It's the same line if the slopes and y-intercepts are the same, so the number of corresponding points are infinite.

yuradex [85]

The correct answer is:  [C}:  " 3 ⁻ ¹ " .

___________________________

<u>Note</u>:  " 3 =  3 ¹  " .

     →   "  3 ⁻ ¹  =  1 / (3 ¹)  = 1 /3 =  \frac{1}{3} " .

_______________________

Let us consider the remaining answer choices:

_______________________

Choice  [A}:  " ( - 1)³ " .    

<u>Note</u>:  " ( - 1)³ "  =  " { - 1 * - 1 * - 1 } " =  " -1 " .  

                →  " -1 " ≠ " \frac{1}{3} " .

                →  So; Choice  [A} is INCORRECT.

___________________________

Choice  [B]:  " (- 3)¹ " .

<u>Note</u>:  " ( - 3)¹ "  =  " -3 " .

                →  " -3 " ≠ " \frac{1}{3} " .

                →  So;  Choice  [B] is INCORRECT.

___________________________

    →  The correct answer is:  [C]: "  3 ⁻ ¹  . "

Best of luck to you!

Complete the proof given RS tangent to circle B at some points R and S​
aliya0001 [1]

Answer:

Step-by-step explanation:

AR⊥RS (tangent line is ⊥ to radius of the circle)

BS ⊥ RS (tangent line is ⊥ to radius of the circle.)

∴ AR and BS ⊥ to same line RS.

Hence either AR and BS are in same line  or parallel.

But they are radii of different circles.

∴ AR ║BS
