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 =
Answer:
45 students speak Spanish at Francis Lewis High School
Step-by-step explanation:
Option1:
18000 = 400x
x = 45 students speak Spanish at Francis Lewis High School
Option2:

0.18 * 250 = 45 students speak Spanish at Francis Lewis High School
If he runs 1/2 a mile in 5 minutes then 60 minutes would be 5x12 and 1/2x12 would be 6 so he can run 6 miles per hour
Answer: 12x-8y
Step-by-step explanation:
Answer:
x = 73°
y = 39°
Step-by-step explanation:
x + 107 = 180 {Linear pair}
x = 180 - 107 {Subtract 107 from both sides}
x = 73°
y + 51 + 90 = 180 {straight line angles}
y + 141 = 180
y = 180 - 141
y = 39°
