Answer:
D.
Step-by-step explanation:
we are given
we can use standard equation of hyperbola
where
center=(h,k)
center at origin
so, h=0 and k=0
vertex is
we can use formula
vertices: (h, k + a)
we get
we can plug k=0
now, we can plug these values
now, we are given it passes through
so, we have
we can plug these values and then we can solve for b
and we get
we can solve for b
and we get
now, we can plug these values
we can simplify it
and we get

PEMDAS
Parenthesis first
-(-16) = 16
24+ 16 +(-1/2)x = 18-(-8)
+(-1/2)x
-1/2x
24 +16 -1/2x = 18-(-8)
-(-8) = 8
24+ 16 - 1/2x = 18 + 8
24+ 16 = 40
18+8 = 26
40 - 1/2x = 26
-40 -40
-1/2x = -14
(-2) -1/2x = (-2)-14
x = 28
Answer:
$14
Step-by-step explanation:
10+14/336= 14
or

Remember you need to write complete questions in order to find exact answers. In this way you haven't provided any function, so I'll choose a quadratic function given by:
So we need to find the entire interval at which this function positive. Put another way:
By using graphing tool, we get the graph shown below. As you can see:
- The function decreases from
- The function increases from
- The graph of the function is a parabola that opens up.
But what is really importan in this problem is that:
- The function is positive over the interval
At this interval the function is positive, that is,

Answer:
b = 5
Step-by-step explanation:
Since you are given two points, you can find the slope (m). Use the equation for slope to find it.
Plug the points into the equation and solve.
Now that you have the slope, you can use it and one of the points given to you to find the equation of the line by using point-slope form.
Plug in the slope and one point and solve.
The equation for the line is (y = -2x + 5). The value for b is 5.
