Answer:
The second one is not true the left side 3 does not equal the left side 7, which means it is not true.
The third one is also not true because the left side 9 does not equal the left side 3, which also means it is not a true statement
Step-by-step explanation:
Answer:
option d
Step-by-step explanation:
We are given with three function
Plug in x=-2 in first function
f(x)= 3 so f(-2) = 3
Plug in x=-2 in second function


Plug in x=2 in second function


Plug in x=2 in third function
f(x)= 2x-3
f(2)= 2(2) -3 = 1
We can see that f(-2)=3 is same for first and second function
also f(2) = 1 is same for second and third functions
So the graph is continuous
option D satisfies the points
The value of x+y is
(x+y)
(1,2)
Answer:
Step-by-step explanation:
60= s+5 + 2s-5 + s
60 = 4s
15 = s
the short side is 15
the 2nd side is 20
the 3rd side is 25
<h3>
Answer: y = 160° y' = 0 </h3>
Step-by-step explanation:
y = 160°
take the derivative of both sides
y'= d÷dx(160°)
the derivative of a constant is always 0
y' = 0
