Answer is 9
To get this answer, we replace h with 2, and replace r with 7. This is because h = 2 and r = 7 is given to us
So
h+r = 2+7 = 9
Answer:
0, one solution
Step-by-step explanation:
Answer:
W = .25
Step-by-step explanation:
We know that is means equals and of means multiply
W = .5% * 50
Changing percent to decimal form
W = .005 * 50
W = .25
Use the calculator to graph the function y = 
In the graph , the coordinates of the vertex is the turning point of the graph.
Given function is the quadratic function. For quadratic function the graph will be U shaped parabola.
There will be only one turning point for parabola
Turning point is the vertex
To find vertex we use formula x= 
y = 
a=2, b= 35
= -6.25
Now plug in
in f(x)

Take common denominator
= -75.125
So coordinates of turning point is (-6.25, -75.13)
The graph is attached below.
Answer:
<h2>x = 40</h2><h2 />
Step-by-step explanation:
fx=2x-50
Find x when fx=30
30 = 2x - 50
add 50 each side
30 + 50 = 2x - 50 + 50
80 = 2x
x = 80 / 2
x = 40
