Which of the rolling equations have exactly one solutions ? ps: (click the picture to see answer choices)

All have exactly one solution

Step-by-step explanation:

a) -13x + 12 = 13x - 13

   +13x         +13x

          12 = 26x - 13

         +13           +13

           25 = 26x

           26     26

          25/26 = x

b) 12x + 12 = 13x - 12

   -12x          -12x

          12 = x - 12

        +12       +12

            24 = x

c) 12x + 12 = 13x + 12

  -12x          -12x

           12 = x + 12

           0 = x

d) -13x + 12 = 13x + 13

   +13x           +13x

         12 = 26x + 13

        -13             -13

          -1  = 26x

          ---      

          26       26

          -1/26 = x

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
