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.
For example let's say Megan has to pay the cab driver $50. Here's the equation 50=1.50x + 5
First you want to get x by itself on one side. So subtract 5 on both sides
50=1.50x + 5
-5 -5
---------------------------
45=1.50x
Now that you have x on one side; however, you want to divide to get the answer.
45=1.50x
-----------------------
1.50
x = 30
So if Megan pay $50 that mean she rode 30 miles

Answer:
h = 3
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by its reciprocal.
So h / (1/2) is the same as h * 2 or 2h
2h = 6
Divide both sides by 2 to isolate the variable h.
2h/2 = 6/2
h = 6/2
h = 3
25 + 60 = $85. 85/200 and x/100. 100 times 85= 8500. Divide 8500 by 200= 42.5 Hope this helps!
