Step-by-step explanation:
step 1. A = P(1 + r/n)^nt. this is the compounding equation where n is the number of compounds, t is the time in years, and r is the rate.
step 2. A = 685(1 + .051/1)^(1(1/4))
step 3. A = 693.57.
(3a-7)^2
1. 9a^2-21a-21a+49
2. 3a(3a-7)-7(3a-7)
3. (3a-7)(3a-7)
4. Combine like terms
The point-slope form if the coordinates are (-1,1) and (1,-1)
y = ax + b = ( - 1 )x + b = - x + b < i guess>
Ok done. Thank to me :>
The slope is 2 at all points on f(x) since f’x is just 2
