Suggesting that you want this in standard form, in terms of quadratic equations, you would technically follow a process similar if not almost exactly like the 2 - step equation method with the exception of separating the (x)s and the equations to find x and then plug it in and what-not.
With that being said you would subtract 5 in (x+5) from said 5 in the second equation and -10 in the first equation in order to get 2x^2+7x-15, you would continue to do the same for the x by subtracting it from both ends making the 7x a 6x because there is a 1 at the beginning of each x if there is no number that is shown already. Which finally gives you the equation (y= 2x^2+6x-15)
Given:
area of square, A = 16 
error in area, dA = 0.03 cm^{2}
Step-by-Step Explanation:
Let 'a' be the side of the square
area of square, A =
(1)
A = 16 = 
Therefore, a = 4 cm
for max tolerable error in length 'da', differentiate eqn (1) w.r.t 'a':
dA = 2a da

da = 
da = 0.0375 cm
Answer:
(2,0)
Step-by-step explanation:
The current coordinate of M are (4,0). This means the side length of OM is 4. To scale down by a factor of 1/2, the side length would become 4*1/2 = 2.
This side is now 2 and would place the point M at (2,0).
