What is the answer to this problem? giving 25 points to whoever tells me!

AB is half AC therefore BC is 10 ft

Use Pythagorean theorem.

(8)^2 + (10)^2 = c^2. Square the left side

164 = c^2. Take the square root of both sides

√(164) = c

EC = √(164).

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

)
