Step-by-step explanation:
Solve the system via elimination (add the equations):
-10y + 9x = -9
+ (10y + 5x = -5)
-----------------------
14x = -14
x = -1
Plug in the value for 'x' into the second equation:
-10y + 5(-1) = -5
Solve for y:
-10y - 5 = -5
--> -10y = 0
--> y = 0
x = -1
y = 0
Answer:
Step-by-step explanation:
Rewrite the differential equation as:
Integrate both sides with respect to x:
Integrate one more time both sides with respect to x:
Now that we find the solution, let's find its derivate:
Evaluating the initial conditions:
Replacing the value of the constants that we found in the differential equation solution:
Not your friend you cause if you add 5 ft+1 5/8 it’s gonna be more than 5.)

The inequality is 35+12.50x is less than or equal to 100.
Answer: 9/14 of a pound each day.
Step-by-step explanation:
We can convert the mixed fraction into an improper fraction:
4 1/2 → 9/2
Now we divide by 7, since there are 7 days in a week:
9/2 ÷ 7
When we divide, by a number, it can be placed in the denominator:
9/2*7 = 9/14
There's no other way to simplify it, so that's our final answer.
