Answer:
x>3, the last option with the open circle
Step-by-step explanation:
Answer:
(x, y) = (-6, 3)
Step-by-step explanation:
Maybe you want to solve ...
Use the first equation to substitute for y in the second:
2x +3(-2x -9) = -3
2x -6x -27 = -3
-4x = 24 . . . . . . . . . add 27, simplify
x = -6 . . . . . . . . . . . divide by -4
y = -2(-6) -9 = 12 -9 = 3
The solution is (x, y) = (-6, 3).
you Need to think of 2 square numbers that add up to make 80
answer:
64 + 16
this means that x = 8 and y = 4
because of the square roots
or
y = 4
and
x = 8
Answer:
10
Step-by-step explanation:
8² = 64
6² = 36
64 + 36 = 100
√100 = 10
