The correct answer is Choice A.
The amount of money is decreasing at a rate of 13% per year. The rate that is shown in the equation is 0.87 or 87%. 87% is 13% lower than 100%. That is the amount of the decrease each time.
Here is a graph. When you use a graphing calculator, it isn't always necessary to solve for y.
Note different colors are used for the different problems. Problem 2 has a dashed line, as described by "Remember, ...".
Answer:
(y -5)(y -i√6)(y +i√6)
Step-by-step explanation:
The expression can be factored by grouping:
(y^3 -5y^2) +(6y -30) = y^2(y -5) +6(y -5) = (y^2 +6)(y -5)
The quadratic factor is the difference of squares, if you consider -6 to be a square. In that view, it can be factored as ...
y^2 +6 = (y -i√6)(y +i√6)
Then the complete factorization is ...
(y -5)(y -i√6)(y +i√6)
Answer: y= 2x + 7
Step-by-step explanation:
Slope intercept form = y= mx + b
You are given slope (m=2) and a point (0,7) so
7 = 2(0) + b
7 = b;
So your equation is y= 2x + 7
-201+189=-12-201=-213+189=-24 . S the sign would be negative(-).
