Keith used the following steps to find the inverse of f, but he thinks he made an error. Step 1 given
Step 2 change f(x) to y
Step 3 switch x and y
Step 4 add 5 to each side
Step 5 divide each side by 7
Step 6 change y to g(x)
Step 7 switch sides of the equation
A.
In step 6, Keith should have switched x and y.
B.
In step 5, Keith should have multiplied each side of the equation by 7.
C.
Keith did not make any errors.
D.
In step 4, Keith should have subtracted 5 from each side.

the monthly balance will be $75,000

step-by-step explanation:

there are no answer choices

step-by-step explanation:

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.
