That is correct
Step-by-step explanation:
180° rotation about origin just means that you have to flip the pre-existing image across the x-axis
Good job!
Answer: In the quadratic formula, if the discriminant is greater than or equal to 0, then the solutions to the quadratic equation will be real numbers. ... Looking at the graph of a quadratic equation, if the parabola does not cross or intersect the x-axis, then the equation has no real solution.
x - Alma's given number
15•x - the number multiplied by 15 (the correct answer)
5•x - the number multiplied by Alma (Alma's answer)
her answer is 150 less than the correct answer:
5•x = 15•x - 150
15x - 150 = 5x
15x - 5x = 150
10x = 150
<u>x = 15</u>
X = arcsin (1/2) = 30 degrees
