Answer:
f(4) =22
Step-by-step explanation:
f(x)=3x+10
Let x=4
f(4)=3*4+10
Multiply
f(4) =12+10
Add
f(4) =22

Answer:
B {6, 6, 7}
Step-by-step explanation:
Which set of numbers may represent the lengths of the sides of a triangle? (A) {2,5,9} (B) {6,6,7} (C) {6,4,2} (D) {7,8,1}
For a given triangle with 3 sides, the sun of the length of any two sides must be greater Than the third side. This can be expressed mathematically as;
Let the side be ;
x, y and z
Then:
x > (y + z) or
y > (x + z) or
z > (x + y)
For A{2,5,9}
(2 + 5) < 9 (does not meet criteria)
For B {6,6,7}
(6 +6) > 7
(7 +6) > 6
Meets all criteria
For C {6,4,2}
(4 +2) is not greater Than 6 (does not meet criteria)
For D {7,8,1}
(7 +1) is not greater Than 8 ( does not meet criteria)
Answer:
steps below
Step-by-step explanation:
This is a contradictory proof of sophistry
f(x+4) = f(x)+f(4) ...(1) when x=0
f(x+4) = f(0+4) = f(4) = f(x) + f(4)
f(x) = f(4)-f(4) = 0
From (1): f(x) = f(x+4) - f(4)
x=-4 <u> f(-4)</u> = f(-4+4) - f(4) = f(0) - f(4) = <u>-f(4)</u> ...(2)
From (1): f(x+4) = f(x)+f(4)
x=4 f(4+4) = <u>f(8)</u> = f(4) + f(4) = 2f(4) = <u>-2f(-4)</u> from (2) ... (3)
f(8) +2f(-4) = -2f(-4) + 2f(-4) = 0
