Answer:
($4.00/x)+($4.50/y)
Step-by-step explanation:
we know that
Apples cost 80 cents for x apples
so
One apple cost $0.80/x
Oranges cost 75 cents for y oranges
so
One orange cost $0.75/y
Find the cost of 5 apples and 6 oranges
Multiply the number of apples by the cost of one apple and multiply the number of oranges by the cost of one orange
so
5($0.80/x)+6($0.75/y)=($4.00/x)+($4.50/y)
Answer:
The function's graphic is the one that is below the first one in th right.
Step-by-step explanation:
If we want to know how much Chelsea earns for dogsitting her neighbours' dogs, we have to form a linear equation, that must have the following formula:
In this case, B is the constant value. We know Chelsea charges 12$ for dogsitting, and that doesn't depend on anything (B). But, if you want to Chelsea to walk your dog, then you'd to pay 2.50$ for each walk (X).
So, if Chelsea doesn't walk the neighbour's dog (x=0), she would be earning 12 dolars.
If she walks four times the dog, she would be earning:
Knowing these two values, we can graph the equation. When x=0, y=12, and when x=4, y=22
The function's graphic is the one that is remarked in the attachment.
