In this case, Principal = $28,000; interest rate = -0.25; # of years = 1

So Decrease in value = $28,000 (0.75)^1 = $21,000.

What is Y-3x=-2 and Y+x=-6

love history [14]

Rearranging the first equation gives:

$y=3x-2$

Substituting this into the other equation gives:

$y+x=-6
\\(3x-2)+x=-6
\\4x-2=-6
\\4x=-4 \\x=-1$

If x=-1:

$y+(-1)=-6
\\y=-5$

So x=-1, y=-5

Also Shana wants the length of the run to be 20 feet. Hence the length of the park is 20 feet.

Here we will use the formula for perimeter to find the width of the run

Perimeter = 2(l+w)

62=2(l+w)

l+w = $\frac{62}{2}$
