Answer:


Step-by-step explanation:

Solving our equation

r = 580 / ( 1432 × 6 ) = 0.06750466

r = 0.06750466

converting r decimal to a percentage

R = 0.06750466 * 100 = 6.7505%/year

The interest rate required to

accumulate simple interest of $ 580.00

from a principal of $ 1,432.00

over 6 years is 6.7505% per year.

Graph of y=(x-3)(x+4)
tekilochka [14]

Answer:

For graph refer to attachment .

Step-by-step explanation:

We need to plot the graph of a given function . The given function is ,

\rm\implies y = ( x - 3)(x+4)

When we will simplify the RHS term we will get ,

\rm\implies y = x( x + 4 ) -3(x + 4 )

Simpify the brackets ,

\rm\implies y = x^2 + 4x -3x -12

Add like terms , we have ,

\rm\implies \boxed{\blue{\rm y = x^2+x -12}}

<u>From </u><u>the</u><u> </u><u>equation</u><u> </u><u>:</u><u>-</u><u> </u>

  • The graph will cut x axis at 3 and -4 as x = 3 and -4 are the roots of the equation .
  • The graph will cut y axis at (0,-12)
  • The vertex of the graph will be (-0.5,-12.5)

<u>For the graph refer to attachment .</u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

Point (7, 0)

Equation y = x - 7

<u>Step 2: Find</u>

  1. Substitute in point [Equation]:                                                                         0 = 7 - 7
  2. Subtract:                                                                                                            0 = 0

Since 0 = 0 is true, then it would be a solution to the equation.
