Jose receives $1270 per year from three

salantis [7]

The answer is. $1500.

Let x represent the amount invested at 5%, then is the amount invested at 8%, and is the amount invested at 6%. Since the total return is $1270:

let money invested at 5%= x

money invested at 6%

= 20000- (X+X-1500)

21500-2x

Total interest for 1 year.

x×5/100+ (x-1500)×8/100+(21500-2x)×6/100 = 1270

5x/100+8(x-1500)/100+(21500-2x)6/100=1270

5x+8x-12000+129000-12x = 127000

x+117000 = 127000

x = 10000

money invested at 8%

=21500-2×10000

= 1500.

How to graph 14x+18y=126

Burka [1]

We need to rearrange this into $y=my+c$
Subtract 14x from both sides
$18y=-14x+126$
Divide both sides by 2
$9y=-7x+63$
Divide both sides by 9
$y=\frac{-7x+63}{9}=\frac{-7x}{9} +\frac{63}{9}$
Plot the point (0, 63/9)
Then pick some x values and put them into the equation to find the respective y values
Then plot those points
Finally join up those points
