Graph the line y=5x. Then graph the line y=x. Then look at them and describe in what ways they are the same or different.
Answer:
standard form: y = -x^2 + 15x
Answer:
see explanation
Step-by-step explanation:
Given
(x - 2)² + 9 = 0 ( subtract 9 from both sides )
(x - 2)² = - 9 ( take the square root of both sides )
x - 2 = ±
yields no real solutions
There is no real number when multiplied by itself gives - 9
In fact the solutions to
are said to be imaginary, that is ± 3i
where i =

Answer:
80
Step-by-step explanation:
80 divided by 1/2 = 40 therefore 40 is 50% of 80
