Answer:
5x +11y +10
Step-by-step explanation:
7x+11y+9-2x+1
Combine like terms
7x-2x + 11y +9 +1
5x +11y +10
Answer: Domain =
Range = 
Step-by-step explanation:
Here, the given function,

Since log( negative number ) = not defined
Also,

Hence, f(x) is defined if x - 1 > 0
⇒ x > 1
Thus, f(x) is defined for all the values that are greater than 1,
⇒ Domain of f(x) = All real number greater than 1,
= 
Now, for the interval
,
f(x) can be any real number.
Thus, the range of the given function = 
C=2(3.14)(radius)
c=2(3.14)(250)
c= 1570
A=138° B=180° C=180° D=138°
This is because angle QRS and QTS would equal 180° Bc they are supplementary. So 180-42=138. And since they are supplementary and vertical angles, angle ST would also be 42° and QT would also be 138° because angle RS is 138°
The correct answer is A, it has -1. While B's got 1.
