Answer:
x-int: x = -7 and y-int: y = 9
Step-by-step explanation:
9x - 7y = -63
x-int: 9x - 0 = -63
x = -7
y-int: -7y = -63
y = 9
It loses 300 dollars in value each year
1500/.2
Answer:
80 degrees
Step-by-step explanation:
If angle E and angle Y are conguent, angle X and F would be congruent making angle F 80 degrees
If <em>x</em> is the number of years from now, that means the <em>current</em> population is when x=0
Therefore, we plug this into the equation:
f(x) = 1200(0.8)^0 = 1200 elk at the park currently
make y the subject
y= 5x + 3
perpendicular line needs the reciprocal of the gradient
y = 1/5x + c
substitute in the point
1 = 1/5(5) + c
5/5 = 1 so the answer is y = 1/5x
hope this is helpful!
