Evaluate the function f(x) = 7x - 8 at the given values of the independent variable and simplify. a. f(7)

b. f(x + 5)

c. f(-x)

Step-by-step explanation:

Given the function :

f(x) = 7x - 8

Evaluate the given values of the independent variable and simplify.

a. f(7)

b. f(x + 5)

c. f(-x)

A.) f(7)

f(7) = 7(7) - 8

= 49 - 8

= 41

B.) f(x + 5)

7(x + 5) - 8

7x + 35 - 8

7x - 27

C.) f(-x)

7(-x) - 8

-7x - 8

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
