14 year it would take to  earn $1000 simple interest on an investment of $800 at 9% annual interest.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Let the number of years be represented as T

Now , the equation will be

The simple interest I = $ 1000

The rate of interest R = 9 %

The principal amount P = $ 800

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

Substituting the values in the equation , we get

1000 = ( 800 x 9 x T ) / 100

On simplifying the equation , we get

72T = 1000

Divide by 72 on both sides of the equation , we get

T = 13.89 years

Therefore , the number of years is approximated to 14 years

Put the following equation of a line into slope-intercept form, simplifying all fractions. 3x+6y=-42

Answers

Answer:

y = -1/2x + 7

Step-by-step explanation:

3x + 6y = 42.  Put everything except the y term on the right hand side, so subtract 3x from both sides.

6y = -3x + 42.  You want 1y by itself, so divide everything by 6.

y = -1/2x + 7

What is Unitary Method ?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

1 ton is equal to 2,000 pounds.

So, 5 tons  and 230 pounds

= 5 x 2000 + 230

= 1000 + 230

= 1230 pounds.

a point moves so that it's y-coordinate is always 2 less than it's x-coordinate.
1) write an equation for it's path
2)where does it cross the x-axis
3) where does it cross the y-axis
4) what is it's slope

Answers

Step-by-step explanation:

y is always 2 less than x

1) y = x- 2

2) where does it cross the x-axis ? that means y = 0.

0 = x - 2

x = 2

3) where does it cross the y-axis ? that means x = 0

y = 0 - 2 = -2

4) the slope is always the factor of x.

in

y = x - 2.

the factor of x is simply +1.

If its y-coordinate is always 2 less than its x-coordinate, this is expressed as y = x - 2

Slope and equations

From the given information

Let the y-coordinate be yLet the x-coordinate be x

If its y-coordinate is always 2 less than its x-coordinate, this is expressed as:

y = x - 2

The equation of the path is y - x - 2

2) The point where th line cuts the x-axis is at y = 0

0 = x - 2

x = 2

The point is at (2, 0)

3) The point where th line cuts the y-axis is at x = 0

y = 0 - 2

y = -2

The point is at (0, -2)

4) The standard equation of a line is y = mx + b where m is the slope. Given the equation y = x - 2

Comparing:

mx = 1x

m = 1

Hence the slope of the equation is 1

x - 4y = -14
(5,6)
(5-6)
(6,5)
(6,-5)

Answers

(6,5)
To cancel a term from both equations you have to multiple the top one by 4 so
4x + 4y = 44
x - 4y = -14
cancel out the y’s from both equations and add the terms from both so you’ll have
5x = 30
divide by 5
x = 6

substitute 6 for x in the first equation
6+y=11
subtract 6 from both sides
y = 5
