<span>the square root of is 47 irrational</span>
Answer:
( 3 
) unit²
Step-by-step explanation:
Subtraction is "addition of the opposite."
8 - 9 = 8 + (-9)
-7 - 2 = -7 + (-2)
-6 - (-3) = -6 + 3
Answer: x = -1 and y = 9
The two equations are:
-9x + 2y = 23
-4x -y = -3
Now find for x in the first equation...
-9x + 2y = 23
-9x = 23 - 2y
x = (23 - 2y)/-9
Now place this value of x in the second equation and find for y...
-4{(23-2y)/-9} - y = -3
-92 + 8y + 9y = -3 * -9
17y = 27 + 92
y = 119/17
y = 7
Now place the value of y in the first equation," -9x + 2y = 23 " and find x
-9x + 2*7 = 23
-9x + 14 = 23
-9x = 23-14
x = 9/-9
x = -1
There you go! Hope it helps
