<span>kilo m = 1000 millimeters </span><span />
Answer:
Domain: {-3, 0, 2, 4, 5)
Range: {1, 2, 3, 7}
The relation is a function because for every x-value there is one y-value. In other words, for every input there is one output.
Answer:
The graph crosses the x-axis at x = 0 and touches the x-axis at x = 3.
Step-by-step explanation:
When you graph this equation, you should see the zeros it passes and touches.
1. y<span> ≤ 4x/3+5
2. y</span><span>< 6x/4+3</span>
5. The 5th figure will have 30 tiles.
6. The 6th figure will have 42 tiles.
7. The pattern is non-linear (quadratic).
8. The 20th figure can be made with 420 tiles.
_____
The Nth figure is made with n*(n+1) tiles. To answer question 8, you must solve
.. n(n +1) = 420
.. n^2 +n -420 = 0
.. (n +21)(n -20) = 0
.. n = 20 or -21 . . . . the negative solution is extraneous
