Solving for X.
5 = 2x^2 + 3 Subtract 3 from both sides.
2 = 2x^2 Divide by 2 on both sides.
1 = x^2 Take the square root of both sides.
X = 1
Slope = m
Equation to find slope is:
m = (y2 - y1) / (x2 - x1)
2 points:
(4,-2) 4 = x1 and -2 = y1
(8,5) 8 = x2 and 5 = y2
So...
m = (y2 - y1) / (x2 - x1)
m = (5 - (-2)) / (8 - 4)
m = 7 / 4 or 1.75
Therefore, the slope of the line is 7/4 OR 1.75.
I believe the answer is 280 because if you add all of the representatives together that it was it equals.
Use A = P (1 + r/n) ^(nt). Assuming that we're dealing with years here, n = 1, so we have
A = P (1 + r) ^(t), where r is the interest rate as a decimal fraction.
The investment decreases in value, so the common ratio r is (1.000-0.012), or 0.988.
Thus, A = $100,000* (0.988) ^25 = $73947.52 is the current value, after 25 years.
