Answer:
y=√x+5 -1
the answer is option C,,
x=-7,y=√-7+5 -1=√-2 -1
we can't find the square root of negative values, therefore it displays as error
x=-6,y=√-6+5-1=√-1 -1
same reason
x=-5,y=√-5+5-1=√0-1=-1
x=-4,y=√-4+5-1=√1-1=0
x=-1,y=√-1+5-1=√4-1=1
x=4,y=√4+5-1=√9-1=2
The value of the expression decreases
The answer would be x = 4 miles.
Answer:
6 days
Step-by-step explanation:
First, we make common denominators:
3 *2 = 6
_ -> _
4 *2 = 8
and we get 6/8
6/8 divided by 1/8 will be 6 days
Vertex<em> </em>is at 
<em>y-intercept</em> is 3.
The parabola <em>opens up</em>.
Step-by-step explanation:
The graph of the equation is hereby attached in the answer area.
Vertex is the point on the parabola where the graph crosses its axis of symmetry. The axis of symmetry here(
), is shown with the dotted line in the graph attached.
<em>y-intercept </em>is defined as the value of y where the graph crosses the y-axis. In other words, when
. Putting
And, the graph opens up as shown the graph figure as well. It is also evident from the co-efficient of
in the given equation
. Here, co-efficient of
So, vertex<em> </em>is at 
<em>y-intercept</em> is 3.
The parabola <em>opens up</em>.
