Answer:
y = -5x + 19
Step-by-step explanation:
Note that the equation of any line parallel to y= -5x+7 has the same form as y= -5x+7, but a different constant. Knowing that this new line passes thru (2,9), we determine the value of this constant as follows: 9 = -5(2) + C, or 9 = -10 + C. Then C = 19, and the equation of this new line is
y = -5x + 19
Answer:
y = -3x + 3
Step-by-step explanation:
Perpendicular slope: -3
y -(-3)= -3(x-2)
y+3= -3x + 6
y = -3x + 3
Answer: Area of the polygon is 43.31 cm^2 t
Step-by-step explanation:
The polygon show in the diagram is a hexagon. It has six sides, since it is a regular hexagon, all the six sides are equal.
From the information given, the apotherm = 5√3
The apotherm is the perpendicular distance from the center of one side of the polygon to the center of the polygon. To determine the area of the polygon,
Area of polygon
=area = a^2n ×tan 180/n
Area = (5√3)^2 tan(180/6)
Area = 5^2×(√3)^2 × tan30
Area = 25×3×0.5774
Area = 43.305
Approximately 43.31 cm^2 to the nearest tenth
