Y=(1/2)x cause the constant variation is 1/2
Answer:
-15
Step-by-step explanation:
g(x) = 3x + 3
Let x = -6
g(-6) = 3*-6 + 3
= -18 +3
= -15
Answer:
An even function is:
f(x) = 7
Step-by-step explanation:
An even function accomplish the following condition:
f(x)=f(-x) (1)
Applying (1), we have:
- f(x)= (x-1)^2
f(-x)
(-x-1)^2 - f(x)= 8x
f(-x)
-8x - f(x)= x^2 -x
f(-x)
(-x)^2 +x
The last one is even.

Answer:
Length = 34
Step-by-step explanation:
Perimeter of rectangle = a+a+b+b = 2(a+b)
Let a = length = 2b - 4
Let b = width
Therefore
(2b-4) + (2b-4) + b + b = 106 cm
Bracket off
2b-4+2b-4+b+b = 106cm
Collect like terms
2b+2b+b+b-4-4 = 106cm
6b-8 = 106
6b = 106+8
6b = 114
b = 114÷6
b = 19
To get a
2b - 4
2(19) - 4
38-4
= 34
