Answer: (2, -3)
The solution of the equation 4x+y=5 and 3x+y=3 be (2 , -3) .
Step-by-step explanation:
As given the equations are .
4x+y=5
3x+y=3
Subtracted 3x+y=3 from 4x+y=5 .
Thus
4x - 3x + y - y = 5 - 3
x = 2
Put in the equation 4x+y=5 .
4 × 2 + y = 5
8 + y = 5
y = -8 + 5
y = -3
Therefore the solution of the equation 4x+y=5 and 3x+y=3 be (2 , -3) .
(2, -3)
Answer:
825 in^3
Step-by-step explanation:
The volume of a cylinder is
V = pi r^2 h where r is the radius and h is the height
We are given the diameter of 10
The radius is 1/2 of the diameter of 1/2 (10) = 5
V = (3) * (5)^2 * 11
V = 3( 25)*11
= 825 in^3
A is the answer. This is because 605/55=w which is the same as
55 x w =605
To simplify things, one could just use differentiation with exponents.
y= 1/(p +ke^p)= (p + ke^p)^-1
dp/dy = -1 - ke^p
