Answer:
Multiple
Step-by-step explanation:
You put the equation in slope intercept form, therefore, the solutions are the entire line!
Every point on the line can be considered a solution.
Answer:
Option D (r(t) = 3.50t +25
; r(8) = 53)
Step-by-step explanation:
The fixed cost to rent the kayak $25. This is the cost which remains fixed irrespective of the usage of the kayak. The variable cost of using the kayak is the cost which depends on the usage of the kayak. It is mentioned that the kayak is used for 4 hours and the company charges $3.5 for every half hour. The cost function is given by:
r(t) = 25 + 3.5t ; there r is the total cost of using the kayak and t is the number of half-hours the kayak is used.
4 hours means that there are 8 half-hours. Therefore, t=8. Put t=8 in r(t).
r(8) = 25 + 3.5*(8) = 25 + 28 = 53.
Therefore, Option D is the correct answer!!!
12.25x + 8.75y > = 90 (thats greater then or equal) <== ur inequality
Answer:
The x intercept is (-2,0)
the y intercept is (0,4)
Answer:
it is not always possible to find their intersection point for e.g take
y=x-1 it's inverse is y=x+1 so their is no intersection point but generally u find intersection points by equalizing their functions
f(x)=f^-1(x)
