Since y = 1/2x + 3
X - 2(1/2x + 3), x/1 - 2x/2 -6/2 = x+3
Or x-x-3=0 which equals -3 so it is inconsistent since it's not dependable :)
Hello!
I will post the graph of the function y = 1/2tan(x) below.
Using this graph, the answer is false. Why? The graph below is graphed at (π, 0) and (-π, 0), while this graph is not graphed at those points. Therefore, it is false.
The discriminant is the part under the sqrt in the quadratic formula
for ax²+bx+c, the discriminant is b²-4ac
if the discriminant is
less than 0, then there are non-real roots
equal to 0, then there is a double root
greater than 0, then there are 2 real roots (may be rational or irrational)
so
1x²-5x+7
b²-4ac=(-5)²-4(1)(7)=25-28=-3
less than 0 so it is non real roots
answer is D
2 represents area Becuase of the area formula
3:4 is the answer. Look at it like a pattern. 9:12, 3 goes into both of them, 12:15, 3 goes into both of them, 12:16, 4 goes into both of them. However nothing goes into both the numbers in 3:4.
