Solve the system of equations.
12x - 5y = –20
y=x+4
2 =
Y=

Answers

Answer:

Solution :

{x,y} = {0/14261512,4}

Step-by-step explanation:

Solve by Substitution :

// Solve equation [2] for the variable y

[2] y = x + 4

// Plug this in for variable y in equation [1]

[1] 12x - 5•(x +4) = -20

[1] 7x = 0

// Solve equation [1] for the variable x

[1] 7x = 0

[1] x = 0

// By now we know this much :

x = 0

y = x+4

// Use the x value to solve for y

y = (-0/14261512)+4 = 4

Answer:y = (-0/14261512)+4 = 4

Step-by-step explanation:[2] y = x + 4// Plug this in for variable y in equation [1]

[1] 12x - 5•(x +4) = -20 [1] 7x = 0// Solve equation [1] for the variable x

[1] 7x = 0

[1] x = 0 // By now we know this much :

x = 0 y = x+4// Use the x value to solve for y

y = (-0/14261512)+4 = 4 Solution : {x,y} = {0/14261512,4}

Steve invests $1,800 in an account that earns 3.7% annual interest, compounded continuously. What is the value of the account after 10 years? Round your answer to the nearest dollar. A. about $2,466 B. about $2,589 C. about $2,601 D. about $2,606

Answers

Answer:

B. about $2,589

Step-by-step explanation:

Given data

P=$1,800

R= 3.7%

T=10years

The expression for the compound interest is given as

A= P(1+r)^t

substitute

A= 1800(1+0.037)^10

A= 1800(1.037)^10

A=1800*1.43809495884

A=$2588.570

Hence the answer is B. about $2,589

If 5x + 4y= 13 and 4x + 5y = 14, find the value of (x - y).

Answers

Answer:

x - y = - 1

Step-by-step explanation:

Given the 2 equations

5x + 4y = 13 → (1)

4x + 5y = 14 → (2)

Subtract (2) from (1) term by term , that is

(5x - 4x) + (4y - 5y) = 13 - 14

x - y = - 1

Answer:

x = 1

y = 2

x - y = -1

Step-by-step explanation:

5x + 4y= 13, then 4y = 13 - 5x, then y = (13 - 5x)/4

4x + 5y = 14

substitute for y:

4x + 5(13 - 5x)/4 = 14

simplifying:

4x + (65 - 25x)/4 = 14

4x + 16.25 -6.25x = 14

-2.25x = -2.25

x = 1

y = (13 - 5)/4 = 2

The table shows a function. Is the function linear or nonlinear?

Answers

Answer:

nonlinear

Step-by-step explanation:

Hey There!

A linear function would have a straight line when graphed meaning that it would have a constant slope

This is a nonlinear function because y is not moving at a constant rate with x

16-8=8

8-2=6

It went down 8 then it went down 6

therefore it is a nonlinear function
