one zero
hope it helped if i didn't please write back and ill try my best for further explanation
There were 60 girls because you do cross multiplication (5 x 48 is 240 4 x 60 is 240)
Answer:
Step-by-step explanation:
The general solution will be the sum of the complementary solution and the particular solution:
In order to find the complementary solution you need to solve:
Using the characteristic equation, we may have three cases:
Real roots:
Repeated roots:
Complex roots:
Hence:
Solving for :
Since we got complex roots, the complementary solution will be given by:
Now using undetermined coefficients, the particular solution is of the form:
Note: was multiplied by x to account for and in the complementary solution.
Find the second derivative of in order to find the constants and :
Substitute the particular solution into the differential equation:
Simplifying:
Equate the coefficients of and on both sides of the equation:
So:
Substitute the value of the constants into the particular equation:
Therefore, the general solution is:
A) The eight pound bag costs less if you divide 7 by 6 you get $1.17 per pound. If you divide 9 by 8 you get $1.13.
B) 1.17 dollars per pound
(Everything above is rounded so do the math to find the more accurate numbers)
Answer:
x=-10
Step-by-step explanation:
you have to first get x on one side so subtract 2x.
x+2=-8
then you have to isolate x, so subtract 2
x=-10
and that's your answer, hope this helped!
