so the value of the function at x=-3 is -192
If charge per day =x
and charge per mile =y
6x + 550y = 337
3x + 350y = 185
multiple the second equation by 2
6x+700y=370
subtract the first equation from this equation
150y=33
y=0.22
Now we plug the y back in to one of the initial equations to get the value of x
3x+350(0.22)=185
x=36
Charge per day is $36 and charge per mile is $0.22
Answer:
(1) let pen = x
let pencil= y
i) y ≤ 5x
ii) 5x + 2y ≤ 40
Step-by-step explanation:
at most = maximum
If a tiger is traveling at 48 mph after 10 hours it will be 480 miles away.
For these problems you'll need to know that the volume on a triangle can be figured out by plugging in given information into the equation: v=1/2 bxh
