Answer:
Step-by-step explanation:
Given is a function f(x)
We have to analyse and sketch the graph
X intercept : Put y =0, we get x=0
Y intercept: Put x =0 , we get y =0
No exception for x or y and hence set of all real numbers is domain and range.
f' becomes 0 not at finite points
So relative extreme
Graph is sketched and attached
Using elimination method. Using substitution will cause some fraction problems.
c- child tickets
a- adult tickets
4a + 7c = $83
5a + 6c = $90
multiply by -5
-20a - 35c = -$415
20a + 24c = $360
-11c= -$55
c = $5 child tickets
4a + 7(5)= $83
4a + 35 = $83
4a = $48
a= $12 adult tickets
Answer:
The answer is -1.255 for residual value.
Step-by-step explanation:
We are tasked to solve for the residual value given that when x equals 29, y will be equals to 27.255. But, when it is tested, y actual value is 26. The formula in solving residual is shown below:
Residual value = Observed value - predicted value
Residual value = 26 - 27.255
Residual values = -1.255
Answer:
(-9,-7)
Step-by-step explanation:
(x,y)—>(-x,-y)
(9,7)—>(-(9),-(7))=(-9,-7)
