Answer:
Step-by-step explanation:
x represents the height of the parallelogram, and also represents the width. As you can see, the parallelogram is longer than the height and width. 5x represents this length. In words, the parallelogram is 5 times longer than it is wide (or 5 times longer than it is high / thick).
A. f(x) = 7 + 0.3x
Just re-read your question! Hope I helped!
Step-by-step explanation:
The x-intercept is the point where the graph touches the x-axis, which means y=0. So let's set y=0 in your equation, and we receive
(x-5)^2 + (0+12)^ = 169
which means
(x-5)^2 = 25
Solve this, and get x=10 or x=0.
This means the x-intercepts are (10,0) and (0,0).
Try doing the same for y.
Answer:
see the procedure
Step-by-step explanation:
Looking at the graph we have
The graph represent a vertical parabola open upward
The vertex is a minimum
The vertex is the point (-4,-3)
The domain is the interval -----> (-∞,∞)
The Domain is all real numbers
The range is the interval ----> [-3,∞)

The range is all real numbers greater than or equal to -3
The graph is increasing in the interval (-4,∞)
The graph is decreasing in the interval (-∞,-4)
The minimum of the graph is y=-3 occurs at x=-4
Gym B should be cheaper by $20 if you go the same number of times.
