Tami earned $20.64 in simple interest by investing a principal of $400 in a Treasury bill.

Mathematics

The number of years she had her investment is after 3 years

<h3>How to determine the years of investment?</h3>

From the question, the given parameters are:

  • Principal Amount, P = $400
  • Interest Rate, r = 1.72%
  • Simple Interest, I = $20.64

The number of years (T) is calculated from the following simple interest formula

I = PRT

Substitute the given parameters in the above equation

20.64 = 400 * 1.72% * t

Express 1.72% as decimal without percentage

20.64 = 400 * 0.0172 * t

Evaluate the product

20.64 = 6.88 * t

Divide both sides by 6.88

20.64/6.88 = 6.88/6.88 * t

Evaluate the quotient

3 = t

Rewrite the equation as

t = 3

This means that she had her investment after 3 years

Hence, the number of years she had her investment is after 3 years

A line has a slope of 5 and passes through the point (-1,2).
Andreyy89

Answer:

Step-by-step explanation:

slope=m= 5

points=(-1,2)

<u>By point-slope form:</u>

y-y_{1}=m(x-x_{1})

<u>Substitute the values in formula:</u>

<u>y-2=5(x+1)</u>        (It is the point slope form)

Now,

<u>Slope intercept form:</u>

y-2=5x+5

y=5x+5+2

<u>y=5x+7</u>

<u />

Exploring Systems of Linear Equations 2x +3y =8 and 3x+y= -2
butalik [34]

The solution of the linear equations will be ( -2, 4).

<h3>What is an equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Given equations are:-

  • 2x +3y = 8 and 3x+y= -2

Solving the equations by elimination method:-

2x +3y = 8

3x+y= -2

Multiply the second equation by 3 and subtract from the first equation.

2x +3y = 8

-9x -3y = 6

----------------

      -7x = 14

         x = -2

Out of the value of x in any one equation, we will get the value of y.

3x+y= -2

3 ( -2) + y = -2

-6 + y = -2

y = 4

The graph of the equations is also attached with the answer below.

Therefore the solution of the linear equations will be ( -2, 4).

The complete question is given below:-

Exploring Systems of Linear Equations 2x +3y =8 and 3x+y= -2. Find the value of x and y and draw a graph for the system of linear equations.
