Answer:
B
Step-by-step explanation:
The number line shows that x must be greater than or equal to 0 and less than but not equal to 3. This means that the only answer that does not reflect this is 0<x<3, because again, x must be greater than or equal to 0. Not just greater than.

Answer:
height of the man is ≈ 6.5
Step-by-step explanation:
shadow of the man/ shadow of the tree = height of the man/ height of the tree
4/11 = x/18 cross multiply
11x = 4(18)
11x = 72
x = 6.5
The answer is B) or y = -4x + 160
If her initial weight is 160 pounds, then you must subtract 4x, representing how much weight she lost over time, to find her current weight y
But, since y = 160 – 4x isn't an option, we can reverse to negatives as long as you change the addition/subtraction sign
So, subtracting positive 4x is the same as adding -4x
Therefore, y = 160 – 4x is the same as y = -4x + 160
