Which quantity is best modeled by a linear function
1 answer:
See the explanation
<h2>Explanation:</h2>Since you haven't provided any options I'll face this problem in a general way. Linear functions are given of the form:
This is called the slope-intercept form of the equation of a line. When modeling a linear function we need to take into account that we will have a constant rate of change and that when plotting our model this will follow a line. In order to model a problem as a linear function we need to follow some tips:
- Identify the changing quantities in order to define the variables that stands for them.
- Draw a diagram or a coordinate system. It is usual to use the Cartesian coordinate system.
- Read the problem in detail.
- Set a mathematical model writing the equation that stands for the problem.
- Set values into the variables in order to check your model.
- Check your results.

Answer:
d. y = -2×
Step-by-step explanation:
First to solve find the slope using the formula, . The slope equals 20/-10 or -2. Then plug the slope and point, (-5,10), into slope-point form. y-10=-2(x+5), then solve for y. This gives you y=-2x+0 or y=-2x.

Answer:
- 160 ft (out from the river)
- 320 ft (parallel to the river)
Step-by-step explanation:
Let x represent the length of fence parallel to the river. Then the dimension of perpendicular to the river will be half the remaining fence: (640-x)/2. The total area will be ...
A = x(640-x)/2
This is the equation of a parabola that opens downward. It has zeros at x=0 and x=640, so its axis of symmetry is x = (0+640)/2 = 320. That is, the peak of the area curve is found when x=320.
The dimensions of the garden with the largest area are 160 ft wide by 320 ft long, where the long side is the river side.
