Answer:
f(x)=5x-6
Step-by-step explanation:
When I entered this in Desmos it crossed through the line crossed through the x and y axis which makes this equation a linear function.
The right answer is y=5x+-5 becuase slope intercept form is coming in handy for this question. hope this helps.
The answer is the last one, y = 2/3 -2
Use the rise over run strategy on linear functions such as this one
Assuming that this field is rectangular with 2 semi-circles (one on both ends of the field), we must first calculate the total area of the field. this is done by adding the area of the rectangular portion and the circular portion. This is done below:
Given:
Rectangular length = 95 yards
Rectangular width = semi-circle diameter = 49 yards
Area of rectangle = length * width = 95 * 49
Area of rectangle = 4655 yd^2
The area of the 2 semi-circles can be obtained by treating both as one circle.
Area of circle = pi * (d/2)^2 = 3.1416 * (49/2)^2
Area of circle = 1885.74 yd^2
Total area = 1885.74 + 4655 = 6540.74
We multiply the area by the cost of fertilizing:
Total cost = cost per sq. yd * total area
Total cost = 0.08 * 6540.74
Total cost = $523.26
Answer:
-- Another point

Step-by-step explanation:
Given


Solving (a): Another point
Substitute 1 for x and 8 for f(x) in 

Remove absolute bracket



Substitute 8 for a in 

Let x = -1

Remove absolute bracket


So, another point is:

Solving (b): The value of a
This has been solved in (a) above
