The two packages mailed together is cheaper.
If seperately:
3 pounds package= $(x+2y)
5 pounds package= $(x+4y)
If combined:
3+5=8 pounds
= $(x+7y)
amount of money saved=$[(x+2y)+(x+4y)]-$(x+7y)
Answer:
4p - 6t
Step-by-step explanation:
7p + 9t - 3p - 15t
= 7p - 3p + 9t - 15t
= 4p + (-6t)
= 4p - 6t
If Angle M is y then,
Step-by-step explanation:
(6y) + (3y -6) + y = 180°
10y - 6 = 180
10y = 186
y= 18.6
Angle O = 3(18.6) - 6 = 49.8
Answer <u><em>4</em><em>9</em><em>.</em><em>8</em></u>
I hope this helps!!!
First look for the fundamental solutions by solving the homogeneous version of the ODE:
The characteristic equation is
with roots and , giving the two solutions and .
For the non-homogeneous version, you can exploit the superposition principle and consider one term from the right side at a time.
Assume the ansatz solution,
(You could include a constant term <em>f</em> here, but it would get absorbed by the first solution anyway.)
Substitute these into the ODE:
is already accounted for, so assume an ansatz of the form
Substitute into the ODE:
Assume an ansatz solution
Substitute into the ODE:
So, the general solution of the original ODE is
ANSWER. No, it is not equal.
Multiply 2(3-4y). It doesn’t equal it: 6-8y.
