Okay the points given are -4,-5 and -2, 1
we know the formula
y2 - y1/x2 - x1
label -4 as x1 and -5 x2
-2 as y1 and 1 as y2
1 - -2 turns into 3
-5 - -4 turns into -1
sp its - 3/ 1
Answer:
20 ounces
Step-by-step explanation:
For this type of problem it is best to work backwards.
If David has 18, and Charlie gave him 1/2, then Charlie has 36 because 18x2=36. Barbara has 60, because 36/3= 12 and 5x12=60. Then, Amanda has 80 because 60/3=20 and 20x4= 80. But, we need to subtract 60 because the problem asks how many ounces of water does Amanda <em>still</em> have. So, 80- 60(The amount of water she gave to Barbara)=20.
Answer:
x = 8/3, y = 22/3
Step-by-step explanation:
5x-y=6-2x+y=8
5x-y=8 --- 1
6-2x+y=8 --- 2
by solving 1 and 2, x = 8/3, y = 22/3
To solve for x^2 - 40 = 9, take the square roots of both sides and solve.
The answer is x = 7, -7.
Answer:
12pi inches
Step-by-step explanation:
The radius is 6 inches.
the formula for circumference is 2(pi)(r). Plug radius in and get 12pi.
