9/27 is equivalent to 2/27
Answer:
<em>y = -4.5x - 22</em>
Step-by-step explanation:
The standard form of finding the equation of a line is expressed as y = mx+c
m is the slope
c is the y intercept
Get the slope:
m = y2-y1/x2-x1
Given the coordinates (-6,5) and (-4,-4)
m = -4-5/-4+6
m = -9/2
m = -4.5
Get the y-intercept
Substitute (-4,-4) and m = -4.5 into y = mx+c
-4 = -4.5(-4) + c
-4 = 18 + c
c = -4-18
c = -22
Get the required equation:
Recall that: y = mx+c
<em>y = -4.5x - 22</em>
<em>Hence the required equation is y = -4.5x - 22</em>
Formula for area of a circle: Pi * R^2.
Radius = diameter/2
Radius = 16m/2
Radius = 8m
Formula and equation:
Pi * (8)^2
= Pi * 64m2
= 201.0 m2.
So, in conclusion, the answer to this question is C)64 * Pi * m^2.
Answer:
Step-by-step explanation:
Let the two angles be x and y
Then: y = 5x - 6
And x + y = 180° (the of supplementary angle is 180°)
Putting y = 5x - 6
x + 5x - 6 = 180
6x = 180 + 6
6x = 186
x = 186/6
x = 31°
And y = 5x - 6
y = 5(31) - 6
y = 155 - 6
y = 149°
The angles are 31° and 149°
