Answer:
$28
Step-by-step explanation:
Time = 4 hours
Charge = $7 / hour
Multiply those two numbers:
4 hour × $7 / hour = $28
Function f(time) = $7 × time
Hopefully this answer helps you :)
The answer to the first one is:
x=-5/4y+-1/2. Why?
In the equation 8x+10y=-4, you subtract 10y form each side which leaves you with 8x=-10y-4. Right? Then you divide each side by 8 which gives you the answer
The answer to the second one is the same answer to the first problem. Why? Because you can already divide each side which gives you x=-5/4y+-1/2.
Hope this helps :^)
Answer:
Minimum: (x, y, p) = (6, 0, 6)
Maximum: (x, y, p) = (2, 8, 18)
Step-by-step explanation:
I find it easiest to solve problems like this graphically. In the attached graph, we have reversed all of the inequalities, so that the feasible region is white, rather than shaded 4 times. I find this makes it much easier to see. The dashed lines indicate that the boundary lines are part of the feasible region (not part of the space outside the feasible region).
Once the slope of the objective function is determined, it is easy to identify the vertices of the feasible region that will maximize or minimize it. P is minimized when its line is closest to the origin. It is maximized when it is farthest away from the origin.
We find ...
p is minimized at (x, y) = (6, 0), where p = 6.
p is maximized at (x, y) = (2, 8), where p = 18.
When your adding, mutiplying, subtracting fractions, it would help to find the GFC or the LMC becuase you have to have a common denominator so you might have to make equivilent fractions.
