Answer:
A number line from negative 10 to 10 is shown with numbers labeled at intervals of 2. An arrow is shown from point 0 to negative 8. Another arrow points from negative 8 to negative 2.
Step-by-step explanation:
find the number line best shows how to solve −8 − (−6)
In the number line first we start with -8 . negative and negative becomes positive
from -8 move 6 units to the right. So it ends at -2
A number line from negative 10 to 10 is shown with numbers labeled at intervals of 2. An arrow is shown from point 0 to negative 8. Another arrow points from negative 8 to negative 2.
The length of a rectangle is three times its width what is the width if the area is 147 square
Answer:
7) a
8) b
9) d
Step-by-step explanation:
0.25x² + 8.5 - 17 = 0
1)
a = 0.25
b = 8.5
c = -17
2)
- 8.5 ± √(8.5)²-4(0.25) (-17)
------------------------------------------
2(0.25)
3)
-34 ± √1428
----------------------
2
4)
