Answer: 7.48 in
Step-by-step explanation:
Choice 2) 44
From definition of a parallelogram, the opposites are equal. Therefore we can conclude that 4x+28=10x+4, then solve.
6x=24
x=4
RS=10x+4=10*4+4=44
Answer is 44. Done!
Answer:
Option B:
Function A has a vertical asymptote at x = 1
Function B has a vertical asymptote at x = -3
Step-by-step explanation:
A function f(x) has a vertical asymptote if:
This means that if there is a value k for which f(x) has infinity or a -infinity then x = k is a vertical asymptote of f(x). Therefore, the closer x to k approaches, the closer the function becomes to infinity.
We can calculate the asymptote for function A.
Then, function A has a vertical asymptote at x = 1.
The asymptote of function B can be easily observed in the graph. Note that the function b is not defined for x = -3 and when x is closest to -3, f(x) approaches infinity.
Therefore x = -3 is asintota of function B.
Therefore the correct answer is option B.
Answer: 7 hours
Step-by-step explanation: For the first 3 hours he traveled at an average speed of 60km. So we would multiply 60 by 3 and get 180. Then we would subtract 180km from 460km. And we would get 280km. Now we would divide 280 by 70km to get 4. Now we add 4 hours and 3 hours to get 7 hours. Answer : 7 hours
