Since both equations define y, they should be equivalent.
3x+7=x-9
2x+7=-9
2x=-16
x=-8
Plug x in
y=(-8)-9
y=-17
Final answer: (-8,-17)
Answer:
both angles are 92 degrees
Step-by-step explanation:
88+c=180
c=92
c and b are vertical angles and all vertical angles are equal
28.875
9.625 (the percent per year)
x3 (years)
= 28.875
Round to cent so about $28.87
Answer:
Step-by-step explanation:
commutative property of addition : x + y = y + x
example : 2+3 =5 and 3+2 =5 then 2+3=3+2
associative property of addition
x + y + z = (x + y) + z = x + (y + z)
example: 2+3+4 = (2+3)+4 = 5 + 4 =9
2+3+4 = 2+(3+4) = 2 + 7 = 9
Answer:
transposition method
Step-by-step explanation:
it helps to find that value of y
