Unfortunately, I do not go to Harvard Business School so I am unable to solve this complex equation.
Answer:
13 =x
z =88
Step-by-step explanation:
7x+1 is a vertical angle to 9x -25
That means they are equal
7x+1 = 9x-25
Subtract 7x from each side
7x-7x+1 = 9x-7x-25
1 = 2x-25
Add 25 to each side
1+25 =2x-25+25
26 = 2x
Divide by 2
26/2 = 2x/2
13 =x
7x+1 and z are supplementary angles, which means they add to 180
7x+1 +z = 180
We know x
7(13) +1 +z = 180
91 +1 +z = 180
92 +z = 180
Subtract 92 from each side
92-92 +z = 180-92
z =88
Answer:
y = -13.75x + 340
120 owls in 2019
Step-by-step explanation:
To find the population in a future year, use the formula y=mx+b since it changes linearly.
So over 4 years the owl population changed from 285-340=-55. Divide by 4 and this is a yearly change of -13.75. This is m.
The y-intercept is the starting point known as b in the equation. Here it is 340.
So the equation is y=-13.75x+340.
In 2019, t=16 so y=-13.75(16)+340 = 120.
