Fist if there is 4 sides on the base you would divide 216/4 =54
Or if there are 2 sides you would divide 216/2= 108
The y-intercept is 4 because it is the only number without a variable
Hey there! I'm happy to help!
Here's how to find the slope given any two points.
Subtract the y values.
14-(-18+-14+18=32
Subtract the x values.
-6-2=-8
And divide those.
32/-8=-4
The slope is -4.
Have a wonderful day! :D

Answer:
A. x = 10 years
B. x = 20 years
Step-by-step explanation:
Given:
y = 0.7(200 - x)
Where,
y = target heart rate in beats per minute
x = person's age in years
How old is a person with a target heart rate of 133 beats per minute?
y = 0.7(200 - x)
133 = 0.7(200 - x)
133 = 140 - 0.7x
133 - 140 = -0.7x
-7 = -07x
x = -7/-0.7
x = 10 years
B. How old is a person with a target heart rate of 126 beats per minute?
y = 0.7(200 - x)
126 = 140 - 0.7x
126 - 140 = -0.7x
-14 = -0.7x
x = -14/-0.7x
x = 20 years
