Answer:
Step-by-step explanation:
Let's examine the individual things
A. x=0 --> y=3.0-5=-5 True
B. x=-1 --> y=3.(-1)-5=-8 False
C. x=5/3 -->y=3(5/3)-5=0 True
D. x=2 --> y=3.2-5=1 True
Answer is B.
You don't understand, you can ask me :)
PR : RC = PQ : AC
so,
PQ = 2.8 inches
Hope this helps
12/20 can be simplified to 3/5
Answer: 128
Step-by-step explanation:
z^2 - z - 72
z^2 - 9z + 8z - 72
<u>Step 1</u>: 72 = 9 * 8 and when we subtract -9+8 = -1 and that's how I went from z^2 - z - 72 to z^2 - 9z + 8z - 72.
<u>Step 2</u>: Taking out common value from first and second; and third and fourth.
z^2 - 9z = z(z - 9)
8z - 72 = 8 (z - 9)
z^2 - 9x + 8x - 72
z(z-9) + 8(z-9)
(z-9) (z+8)
