Iam stumped on this breakdown 1/2(6x-8)-2=39

1/2(6x-8)-2=39

.5(6x-8)-2=39

3x -4 -2 = 39

3x-6=39

3x-6+6=39+6

3x=45

3/3x=45/3

x=15

Step-by-step explanation:

1/2(6x-8)-2=39

.5(6x-8)-2=39

3x -4 -2 = 39

3x-6=39

3x-6+6=39+6

3x=45

3/3x=45/3

x=15

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

i belive those are the ones that are under 90 degreese.
