Answer:
83
Step-by-step explanation:
its a guess bc its a right triangle and right triangle is 90 degrees minus 7 is 83
Notice those two points on the "linear graph", the first point is at (1965 , 140) and the second point is at (1990 , 100).
the rate or average rate of change, namely the slope will then be
If the exponent, n, is a 2, then there will be 2 solutions. Always. The number of solutions to a polynomial is equal to the highest degree in the polynomial. So if n is 2, then and only then will you have 2 solutions.
