Step-by-step explanation:
9x+79+56=180(sum of angles of triangle)
9x+135=180
9x=180-135
x=45÷9
x=5
1.
The formula of a slope (m):

We have the points (7, 8) and (3, 10). Substitute:

2.
a) point-slope form:

Substitute:

b) slope-intercept form:


Answer:
The total yearly cost is $300 at each gym for 50 visits.
Step-by-step explanation:
Healthy Gym: 6n = t
Fitness Gym: 50 + 5n = t
When n = 50 visits, then...
Healthy Gym: 6(50) = $300
Fitness Gym: 50 + 5(50) = $300
The Golden number is one of the roots of x²-x-1=0 and x = (1+√5)/2= 1.618
It's just a mathematical constant you can come across in trigonometry, geometry, sequence like Fibonacci and others. You may find it in fractals also and in many shapes in the nature but not necessarily always true.
It might be a coincidence in some natural shapes, but definitely it is a recognized math contant useful in many math domains
