Answer:
Option a. is the correct option.
Step-by-step explanation:
In the question given graph is y = x² which is transformed into y = -x²-5
then we can interpret the graph as below
1). y = -x²-5 is a function of a parabola.
2). Since the graph is in the form of y = ax²+b
Now if we reverse/reflect the graph on x axis then a becomes -a.
Therefore y = -x² - 5 gets reflected over the x-axis.
3) Since b represents the y-intercept, if it's negative then graph is shifted down and for positive b graph is shifted upwards. Here -5 shows the shift of 5 downwards.
Therefore option a is the correct option.
Substitution because to find x, you would have to substitute -4 for w.
Answer:
3
Step-by-step explanation:
I have showed the steps in the attached image.
Answer:
x^2 + 5n = 4mx
=> x^2 - 4mx + 5n = 0
D=0 (since one root then roots are equal)
b^2-4ac = 0
(-4m)^2 - 4(1)(5n) = 0
16m^2 - 20n = 0
16m^2 = 20n
8m^2 = 10n
4m^2 = 5n
