Answer:
C - 13*
Step-by-step explanation:
Answer:
you just gotta look at the angles, the middle letter is usually what's being focused on
17. angle QMR is less that TMS
18. angle QMR and angle TMS are supplementary angles
19. angle QMR and angle MTS are vertical angles
20. If measure angle QMT = 70 degrees, then measure angle RMS is 70 degrees because they are congruent
Step-by-step explanation:
Answer with Step-by-step explanation:
We are given that

For each real number 
To prove that f is one -to-one.
Proof:Let
and
be any nonzero real numbers such that

By using the definition of f to rewrite the left hand side of this equation

Then, by using the definition of f to rewrite the right hand side of this equation of 

Equating the expression then we get




Therefore, f is one-to-one.
Step-by-step explanation:
First I do it as separate equations 2x-7=0 and 5x+3=0. In this equation you get two answers so you first answer 2x-7=0
2x-7=0
+7 +7
2x=7
/2 /2
x=7/2
Then do 5x+3=0
-3 -3
5x=-3
/5 /5
x= -3/5
Then you can check by putting them back in.
