Answer:
-8r
Step-by-step explanation:
r- 9r
since there is an r in each term we can factor out an r
r (1-9)
r (-8)
-8r
Answer:
C = 66 cm
Step-by-step explanation:
C = pi*diameter
C = pi*21
C= 65.9734457254
C is around 66 cm (when rounded to whole number)
So given the values above, if 4 pounds costs $16, this would mean that per dollar or $1 is 0.25 pounds. And the equivalent of 0.25 pounds to ounces is 4. Therefore, the given rates above are equivalent. Hope this answers your question. Have a great day!
Answer:
The coordinates of A is (-6, -8).
Step-by-step explanation:
Please see attached picture for full solution.
Let's check!
Since T is the midpoint of AB, the distance TA and TB would be the same.
distance formula= √[(x₁-x₂)²+(y₁-y₂)²]
TA= √[(-3+6)²+(-2+8)²]
TA= √45
TB= √[(0+3)²+(4+2)²]
TB= √45
✓ Thus T is indeed the midpoint of AB when A is (-6, -8).
