Answer:
(x, y) = (19, 20)
Step-by-step explanation:
The coefficients of y are opposites, so we can add the two equations to eliminate y.
(-3x +8y) +(-5x -8y) = (103) +(-255)
-8x = -152
x = 19 . . . . . . . divide by -8
Substituting into the first equation, we have ...
-3(19) +8y = 103
8y = 160
y = 20
The solution is (x, y) = (19, 20).
Answer:
the probably could be 0.8 at most since there are other colours
with the pythagorean theorem
using the formula of the quadratic equation
the length cannot be negative, therefore x=7
length of the shorter leg is: 7ft
length of the longer leg is: 3+3(7)= 24ft
length of the hypotenuse is: 4+3(7)= 25ft
