so 25 m=25*100=2500cm
Answer:
(- 8, - 17 )
Step-by-step explanation:
Given the 2 equations
y = 3x + 7 → (1)
y = x - 9 → (2)
Substitute y = 3x + 7 into (2)
3x + 7 = x - 9 ( subtract x from both sides )
2x + 7 = - 9 ( subtract 7 from both sides )
2x = - 16 ( divide both sides by 2 )
x = - 8
Substitute x = - 8 into either of the 2 equations for corresponding value of y
Substituting into (2)
y = - 8 - 9 = - 17
Solution is (- 8, - 17 )
Option 3
Rewrite the second equation and subtract the first. This is like changing the sign on every term of the first equation
