Match each differential equation to a function which is a solution.
functions
a. y=3x+x2y=3x+x2,
b. y=e−4xy=e−4x,
c. y=sin(x)y=sin⁡(x),
d. y=x12y=x12,
e. y=6e3xy=6e3x,

differential equations

1. y″+y=0y″+y=0
2. y′=3yy′=3y
3. 2x2y″+3xy′=y2x2y″+3xy′=y
4. y″+6y′+8y=0y″+6y′+8y=0

1 - C

2 - E

3 - no answer

4 - B

Step-by-step explanation:

A.

So, A is not an answer for 1

So, A is not an answer for 2

So, A is not an answer for 3

So, A is not an answer for 4

B.

So, B is not an answer for 1

So, B is not an answer for 2

So, B is not an answer for 3

So, B is an answer for 4

C.

So, C is an answer for 1

We jump to

D.

So, D is not an answer for 2

So, D is not an answer for 3

E.

So, E is an answer for 2

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
