Answer:

Step-by-step explanation:

We have 2 equations represented by the lines on the graph

5x + 4y = 20

2x - 6y = 12

To plot the first equation on the graph, we a assume different points

4y = 20 - 5x

y = (20-5x)/4

y = 5 - 5x/4

If x =0, y = 5

If x = 2, y = 2.5

If x = 4, y = 0,

These points corresponds to the first line that cuts the positive y axis.

The first line that cuts the positive y axis is represented by the equation,

5x + 4y = 20

Since the left region of the line representing equation is shaded, the unshaded side represents

5x + 4y lesser than 20

To plot the second equation on the graph, we a assume different points

-6y = 12-2x

y = (2x-12)/6 = x/3 - 2

if x= 0, y = -2

If x = 3,y = 1

These points corresponds to the second line that cuts the negative y axis.

The second line that cuts the negative y axis is represented by the equation,

2x -6y = 12

Since the downward region of the line representing the equation is shaded, the unshaded side represents

2x -6y greater than 12

A bank loaned out $33,500, part of it at the rate of 12% annual interest, and the rest at 14% annual interest. The total interes
algol13

Answer:

  • $17,500 at 14%
  • $16,000 at 12%

Step-by-step explanation:

Let x represent the amount loaned at 14%. Then the total interest earned is ...

  0.14x +0.12(33,500 -x) = 4,370

  0.02x = 350 . . . . . . . . . . subtract 4020 and simplify

  x = 17500 . . . . . . . . . divide by 0.02

The amount loaned at 12% is $33,500 -17,500 = $16,000.

  $17,500 was loaned at 14%

  $16,000 was loaned at 12%
