Answer:
At least two of the opposite sides must be parallel.
Step-by-step explanation:
In the picture below, the segment AB must be parallel to the segment DC so that the figure can be called a trapezoid.
Answer:
15y=-1/3x+5
Step-by-step explanation:
-5x15y=-5x+75
2x^4
13b-10
5y+10
5a^3
2b^2+8a
Let's say hmm let's use the figures in thousands, so
model A costs 90 + 4 per year, so... ok.. after "t" years, then the cost for model A is then 90 + 4*t, or
A = 90 + 4t.
now, model B is 70 + 10 per year, so,... after "t" years, model B is then
B = 70 + 10 * t, or
B = 70 + 10t.
if we were to assume A < B, namely the cost of A is less than B, what would the years be? namely, what's "t"?

after that period, then A becomes cheaper than B.
You round down so 2.3 goes to 2
