Answer:
C) any eqaution that has a variable or number squared is a qaudratic equation
They each practice 6 days a week so yes. 14 days= 1 week You can then do this by taking 24/4=6 and 12/2= 6
Let's say is "x", so, then "x" is the 100%, and we know that the 60% is 120, what the dickens is "x" anyway?
Answer:
put 0 in y<=2x+4
y<=4
so if y=4, then y<=2x+4 is true, but y can not equal 4 because they don't want y<2x+4 be true. So y should be 3, 2, 1, 0.
(0, 2)
put -2 in y<=2x+4
y<=0
so if y=0, then y<=2x+4 is true, but y can not equal 0 because they don't want y<2x+4 be true. So y should be negative.
(-2, -1)
√105
if u see its factor are only 3,5,7 so it cant be simplify
answer should be √105
B
