Answer:
If z<7, then z-7 is negative, and |z-7| is positive. So, with the understanding that z-7 is positive, the first part of this expression becomes:
7-z for z<7
Similarly: if z<7, then z-9 is negative and |z-9| is positive. Thus, -|z-9| is equivalent to (9-z).
|z−7|−|z−9|, if z<7 becomes (7-z) - (9-z) for z<7. Simplifying this, we get:
7 - z - 9 + z = -2
Answer:
6 to 9 meals
Step-by-step explanation:
9 If he feeds 2 pounds per meal. 18÷2 =9
6 if he feeds 3 pounds per meal. 18÷3=6
You can cut it in 4 pieces
Answer:
No, because M can be any number
Step-by-step explanation:
P would then equal (-4,7) after the reflection
Don’t let R confuse you as it stands for Reflection. In this question you want to do a reflection across the y-axis.
The formula for reflection across the y-axis is (-x,y). In meaning as you cross the y-axis you y-value will always stay the same while your x-value with the opposite of what it is currently.
With that being said you want to plug in your values from point P to the formula which will leave you with (-4,7)
