Answer:
y = 
x + 4
Step-by-step explanation:
We are to find the equation of line 1 which passes through point (-4,6)
Line 1 is perpendicular to line 2.
The equation of line 2 is; y = 
x + 5
The slope of line 2 is
Because the product of two perpendicular line is -1;
The slope of line 1 is -1 ÷ = 
Taking another point (x,y) on line 1;
Slope = change in y ÷ change in x
= 
y - 6 = (x + 4)
y - 6 = x - 
y = - + 6
y = x + 4
Simplify brackets
10x - 4 = 8x + 14
Add 4 to both sides
10x = 8x + 14 + 4
Simplify 8x + 14 + 4 to 8x + 18
10x = 8x + 18
Subtract 8x from both sides
10x - 8x = 18
Simplify 10x - 8x to 2x
2x = 18
Divide both sides by 2
x = 18/2
Simplify 18/2 to 9
<u>x = 9</u>

Answer:
Yes f is a function of x
Step-by-step explanation:
f(x) means fuctoin of x thats what it stands for.
and it has a constant ratio of 1/2. Hope this helps!!

Hello from MrBillDoesMath!
Answer:
x = 0, 7
Discussion:
f(g(x)) =
f ( x^2-7x) =
1/ ( x^2 - 7x)
The points NOT in the domain are those where the denominator, x^2 - 7x = 0.
x^2 - 7x = 0 => factor x from each term
x(x-7) = 0 => one or both terms must each 0
x = 0 or x =7
Thank you,
MrB
