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
The answer is 72 and 73. When you add 72+73 it equals 145.
The answer is d to the question
Answer:
The size of the cardboard should be 
Step-by-step explanation:
The diagram for this question is shown on the first uploaded image
The volume of the box is 
The length and the Width of the card is
L = W = Z
From the question we are told that 7 in squares were cut from each corner
So the length and the width of the box would be
L = W = (Z - 7)
And the height would be H = 7 in
Mathematically the volume of the box can be represented as

So the Volume would be
Substituting values


=> 

Answer:
The anwser to your question would be negative 23 (-23)
