Property being demonstrated here is alternate angles.
Therefore, y = 60
-6x + 100 = -10x + 160
+ 10x + 10x
4x + 100 = 160
- 100 - 100
4x = 60
4 4
x = 15
Answer:
S = π( 2(9) + 2(3)(14))
Step-by-step explanation:
Here we are to select which of the options best describe the equation that could be used to find the surface area of the cylinder.
Mathematically,
the surface area of a cylinder can be calculated using the formula
S = 2 π r^2 + 2 π rh
from the question, we have r as d/2 = 6/2 = 3cm and h = 14cm
We plug these two values into the equation above
Thus, we have
S = 2 * π * 3^2 + 2 * π * 3 * 14
S = π( 2(9) + 2(3)(14))
1. x>3
2. x+44
mathpapa" is a great resource for step by step equation solving.
Answer:
y = -2x+1
Step-by-step explanation:
The slope is found by
m = (y2-y1)/(x2-x1)
= (-1-5)/(1--2)
= -6/(1+2)
= -6/3
= -2
Then we can use point slope form to make an equation
y-y1 = m(x-x1)
y-5 = -2(x--2)
y-5 = -2(x+2)
Distribute
y-5 = -2x -4
Add 5 to each side
y-5+5 = -2x-4+5
y = -2x+1
This is in point slope form
