Perpendicular lines are lines that, when intersect the original line, form a right angle. This is formed when two lines' gradients are the negative reciprocals of each other.
In essence,
Now let 5 be
Thus,
That means any line with a gradient or slope of
is a line that is perpendicular to this line.
In essence, the general equation would be:
f(x)=3/4 x+3
g(x)=3x+4
The new function g(f(x)) will be:
g(f(x))=3(3/4 x+ 3)+4
g(f(x))=9/4 x+9 +4
g(f(x))=9/4 x +13
If x=20; then :
g(f(20))=(9/4)(20)+13
g(f(20))=45+13
g(f(20))=58
Answer: the selling price of 20 muffins will be $58.
(x/-3)+2=39
minus 2 both sides
(x/-3)=37
times both sides by -3
x=-111
