Answer:
E
Step-by-step explanation:
Irrational means cannot be put into a fraction. Or random repeating decimals is how I remember it.
√48 can be simplified to equal 4√3. √3 cannot be put into fraction form.

The answer is negative 80 or like this -80
Hi there
y = -x + 1
2x - y = 5
Let's use the substitution method as they asked :)
Substitute -x + 1 for y in 2x - y = 5
2x - (-x+1) = 5
2x + x - 1 = 5
3x - 1 = 5
3x = 5 + 1
3x = 6
x = 6/3
x = 2
Now we need to substitute 2 for x in y = -x + 1
y = -x + 1
y = -2 + 1
y = -1
Final solution : X = 2 and Y = -1
I hope you have a wonderful Christmas.
