Can you show all the answer choices, so I know if I am correct or not?
Domain is (-10, infinity) and range is negative infinity, positive infinity.
Y-2=-3/2(x-2)
first of all, the slope of the line is -3/2, and there's only one equation that has that as a choice for the slope. Then you can take the x and y coordinates given in that equation you want to check and see if the line goes through that point. from the equation, (point-slope form y-y=m(x-x)) I know that the line should pass through point (2, -2), and looking at the graph, that is correct.
Answer:
a) 300 + 80h = x
b) $780
Step-by-step explanation:
So, the original cost is $300, plus an additional $80 times the number of hours rented.
h will represent the number of hours rented
x will represent our total cost (use whatever variable your teacher expects :))
300 + 80h = x
This is our equation. Now, we want to find the cost for 6 hours. Substitute 6 in for h.
300 + 80(6) = x Solve for x.
300 + 480 = x
780 = x This means the total cost for 6 hours will be $780.
Hope this helps :)
NOTE: I noticed in part a, it referred to a "dunking booth". I solved this problem as if that was a typo and they were referring to the jumper.
Answer:
926% and I'm pretty sure the other one is 0.7
Step-by-step explanation: For a you have to remove the decimal. for b you have to remove the %
