sugar
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
By using intersecting chord theorem:
NH.HT=MH.HY
(x+20)*8=12*20
x+20=12*20/8
x+20=240/8
x+20=30
x=30-20
x=10
Answer:
The first Gym when he joins we will have to pay 60 dollars and in a 30 witch cost 90 dollers. but the second gym cost 50 $ per month so the first gym in a year he will pay 450$ and the second one 600 so the first one is cheeper.
Step-by-step explanation:
Answer: 
Step-by-step explanation:
1. Substitute
into first equation and solve for "x" in order to find the x-intercept of the first line:

2. Substitute
into the first equation and solve for "y" in order to find the y-intercept of the first line:

Knowing that first line passes through the points
and
, you can graph it.
3. Substitute
into second equation and solve for "x" in order to find the x-intercept:

4. Substitute
into the second equation and solve for "y" in order to find the y-intercept of the second line:

Knowing that second line passes through the points
and
, you can graph it.
The solution of the system of equations is the point of intersection between the lines. Therefore, the solution of this system is:
