slope (m ) = , y - 1 = ( x - 2)
The equation of a line in ' point- slope form 'is
y - b = m (x - a)( m is the slope and (a , b ) a point on the line )
To calculate m use the ' gradient formula'
m = (y₂ - y₁ )/(x₂ - x₁ )
let (x₁, y₁ ) = (2 , 1) and (x₂, y₂ ) = (14 , 31) ← values chosen from table
m = (31 - 1 )/(14 - 2 ) = =
equation in point- slope form using m = and (a,b )= (2 , 1)
y - 1 = ( x - 2)
Answer:
Its a
Step-by-step explanation:
Here, Subtract second equation from first, in order to eliminate x,
So, 10y = 40
y = 40/10
y = 4
Now, substitute the value in 1st equation,
-2x + 8(4) = 14
-2x = 14 - 32
-2x = -18
x = 18/2
x = 9
In short, Your Answer would be (9, 4)
Hope this helps!
Here is the solution..x equals to √3..which is equals to 1.73205
Answer:
SA = 156π
Step-by-step explanation:
The formula for surface area of a cylinder is
SA = 2πr² + 2πrh where r is the base radius, and h is the height.
We are given r = 6 and h = 7. Plug in those values and evaluate...
SA = 2π(6²) + 2π(6)(7)
SA = 2π(36) + 2π(42)
SA = 72π + 84π
SA = 156π
