Asystem of equations is shown below.
5x + 3y = -6
2x + y = -4.
which statement about the ordered pair (-6, 8) is true? show your work.
a. it is the only solution to the system
b. it is not a solution to either equation
c. it is one of many solutions to the system
d. it is a solution to the first but not the second equation

Step-by-step explanation:

(-6,8)...x = -6 and y = 8

lets start subbing

5x + 3y = -6

5(-6) + 3(8) = -6

-30 + 24 = -6

-6 = -6

so (-6,8) IS a solution to this equation

2x + y = -4

2(-6) + 8 = -4

-12 + 8 = -4

-4 = -4

so (-6,8) IS a solution to this equation

A. It is the only solution to the system

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784
