Y = mx + b is slope intercept form
x = -10
y = 8
m = 6
1. Solve for b
8 = (6)(-10) + b
b = 68
2. Plug m and b back into your slope intercept equation
y = 6x + 68
Answer:
x = 15
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
8x - 7 + x + 7 + 2x + 15 = 180 , that is
11x + 15 = 180 ( subtract 15 from both sides )
11x = 165 ( divide both sides by 11 )
x = 15
your formula will ALWAYS be Y=MX+B
3x + Y = 6
subtract 3x from each side
Y = -3x + 6
you’ll use rise over run, 1/3 will be your ratio.
To solve the inequality:
Add 1 to the sides of the inequality:
Then
Dividing all the inequality by 5, we have:
Graphically:
Or, in the interval notation(-1, 1/5).
Two solutions:
1. x =(100-√2160)/2=50-6√ 15 = 26.762
2. x =(100+√2160)/2=50+6√ 15 = 73.238
