Each month she puts in 20......therefore annually she deposits (20 * 12) = 240 y = 240x + 200
Utilizing the Law of Sines (sinA/a=sinB/b=sinC/c) and recognizing that the angles in a triangle add up to 180°.
The angle C calculates to 180-53-17=110°
Thus, we have 27/sin53=b/sin17=c/sin110
This leads to b=27sin17/sin53, c=27sin110/sin53
The perimeter is defined as a+b+c, so
p=27+27sin17/sin53+27sin110/sin53 units
p≈68.65 units (rounded to the nearest hundredth of a unit)
1/2x + y = 3
Rearrange the equation to achieve the slope-intercept form. (y=mx+b)
1/2x + y = 3
Eliminate 1/2x from both sides.
y = -1/2x + 3
The y-intercept (where the line intersects the y-axis) is three, and the slope (the change in y over the change in x) is -1/2.
Hope this helps!
