Answer:
t+4 / t-4
Step-by-step explanation:
(t^2 - 16) / (t^2 -8t +16)
=( t^2 - 4^2) / (t^2 - 2*4*t + 4^2)
by formula a^2 - b^2 = (a+b)(a-b)
= (t+4)(t-4) / (t-4)^2
= (t+4)(t-4) / (t-4)(t-4)
= t+4 / t-4
Answer:
- see attached for a graph
- solution: (x, y) = (-1, 3)
Step-by-step explanation:
The first line has a slope of -3 and a y-intercept of 0. It will go through the origin and the point (-1, 3).
The second line has a slope of 1 and a y-intercept of 4. It will go through the points (0, 4) and (-4, 0).
The solution to the system of equations is the point where the lines cross, (-1, 3).
