Mathematics

Take 2 points (J,K)

  • (2,24)
  • (4,20)

\\ \tt\longmapsto m=\dfrac{20-24}{4-2}=\dfrac{4}{2}=2

Equation

\\ \tt\longmapsto K-24=2(J-2)

\\ \tt\longmapsto K-24=2J-4

\\ \tt\longmapsto K=2J+20

Answer:

A trend line is a straight line that illustrates the points on a scatter plot.  

The equation of the trend line is: k = -2j + 24

Step-by-step explanation:

From the graph, we have the following points

(j, k) = (6, 12)(4, 16)

Start by calculating the slope

m = k2 - k1 / j2 - j1

So, we have:

m= 16 - 12 / 4 - 6

m = 4 / -2

m= -2

The equation is then calculated as:

k=m(j – j1) + k1

This gives:

k= -2(j - 6) +12

Expand

k= -2j + 12 +12

k= -2j + 24

qwelly [4]

Answer:

$72,100

Step-by-step explanation:

To calculate the total principal+interest payment, you can use the formula to find the future value:

FV=PV(1+i)^n

FV= Future value

PV= Present value= $58,200

i= Interest rate= 7.40%

n= Number of periods of time= 3 years

Now, you can replace the values on the formula:

FV=58,200*(1+0.0740)^3

FV=58,200*(1.0740)^3

FV=72,100

According to this, the answer is that the  total principal + interest  payment will be $72,100.

Can you always use grouping to factor
Softa [21]

Answer:

No

Step-by-step explanation:

it's not always possible to factor a quadratic expression of this factoring by grouping. The method doesn't work when an expression cannot be factored as (Ax+B)(Cx+D) where A, B, C and D are integrers.

In that case, you should use other methods.
