Anyone know how to do this one?

Answer:

5-1=4 and 5+4=9

Step-by-step explanation:

[tex]\huge\red{ƛƝƧƜЄƦ}[/tex]

System of Linear Equations entered :

[1] x - y = 4

[2] x + y = 9

Graphic Representation of the Equations :

y + x = 4 y + x = 9

Solve by Substitution :

// Solve equation [2] for the variable y

[2] y = -x + 9

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

[1] x - (-x +9) = 4

[1] 2x = 13

// Solve equation [1] for the variable x

[1] 2x = 13

[1] x = 13/2

// By now we know this much :

x = 13/2 y = -x+9

// Use the x value to solve for y

y = -(13/2)+9 = 5/2

Solution :

{x,y} = {13/2,5/2}

If Hank has the choice of taking out a 30-year loan for $165,000 at 9.1% interest. The amount that the monthly payment for the 20-year loan is more than the monthly payment for the 30-year loan is: B. $155.66.

For 30-year loan

P= principal = $165,000

r = Rate = 9.1% /12 = 0.00758

n = Number of months= 30years × 12 months = 360

So,

Monthly payment = 165,000×0.00758 × ( 1+0.00758)^360 / (1+0.00758)^360 -1

Monthly payment = 165,000×0.00758 × ( 1.00758)^360 / (1.00758)^360 -1

Monthly payment = 18,957.7574/14.15771760

Monthly payment = $1,339.04

For 20-year loan

P= principal = $165,000

r = Rate = 9.1% /12 = 0.00758

n = Number of months= 20years × 12 months = 240

So,

Monthly payment = 165,000×0.00758 × ( 1+0.00758)^240 / (1+0.00758)^240 -1

Monthly payment = 165,000×0.00758 × ( 1.00758)^240 / (1.00758)^240 -1

Monthly payment = 7,660.239666/5.12476186615

Monthly payment = $1,494.7

Difference = $1,339.04 - $1,494.7

Difference = $155.66

Therefore the correct option is B.

The answer is there is no solution.

Answer:

No solutions

Step-by-step explanation:

2 | x - 7 | = -4       We need to isolate the absolute value, so in order to do that we need to divide 2 from both sides of the equation.

| x - 7 | = -2

Absolute values can not be equal to a negative number.

Therefore, your answer is no solutions.

Answer:

2601

Step-by-step explanation:

The integers between 5 and 102 are

7, 9, 11, 13, 15, 17,19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99, 101

The sum of the odd intergers between 2 and 105 can be calculated as follows

= (N + 1/2)^2

= (101 + 1 /2) ^2

= (102/2)^2

= 51^2

= 2601

Hence the sum of the odd intergers between 5 and 102 is 2601

Integers, whole numbers and natural numbers are numbers without decimal points.

The set of number that are integer but not whole or natural number is:

Answer:

f(- 2) = - 4

Step-by-step explanation:

To evaluate f(- 2) substitute x = - 2 into f(x) , that is

f(- 2) = (- 2)² + 3(- 2) - 2 = 4 - 6 - 2 = - 4

Value of f(-2) is -4

Given that;

f(x) = x²+3x-2

Find;

Value of f(-2)

Computation:

Given that;

f(x) = x²+3x-2

By putting x = -2

f(-2) = (-2)² + 3(-2) - 2

f(-2) = 4 - 6 - 2

f(-2) = 4 - 8

f(-2) = -4

So, -4 is the correct answer to the given equation.
