The first answer and the last one
Plug in each number into their designated spots.
Example with (0,5)
0 goes into x and 5 goes into the y variable and this is the equation now:
2*0 +4*5=20
0 times 2 = 0 and 4*5=20
So that is one of the correct answers.
Repeat the process and you find that the last option is also correct.
17+3=20
740/20=37 Classes
37 classes x 3 faculty members=111
Answer:
x = 8
y = 21
Step-by-step explanation:
y = 4x − 11
x + y = 29
Solve for x:
x + y = 29
x + 4x − 11 = 29
5x − 11 = 29
5x = 40
x = 8
Solve for y:
y = 4x − 11
y = 4 × 8 − 11
y = 21
Answer:

Exponential decay
Step-by-step explanation:
We are given that

y=20 when t=0

Taking integration on both sides then we get

Using formula

Using formula




Substitute y=20 and t=0

Substitute the value of C

When t tends to infinity then

When time increases then the value of function decrease
Hence, the function is exponential decay.
