Point slope form:
m=slope
(x1,y1)
First we need to find the slope using the slope formula:
Given the two coordinates:
<span>(1, 9) and (−1, 11)
Plug them into the slope formula:
</span>
Simplify:
<span>
Now we know that:
m=-1 and the (x1,y1) would be </span><span>(1, 9)
</span>
Now we simply plug in the info:
Final answer: y − 9 = −(x − 1)
Answer:
14 minutes
Step-by-step explanation:
10 times 14 = 140
15 times 14 = 210
200+210 = 410
550-140 = 410
Answer:
Bag 1: 20
Bag 2: 40
Step-by-step explanation:
Let x be the amount taken out of bag 2
Then the amount left in each bag can be written as:
Bag 1: 50-3x
Bag 2: 50-x
Since we know that half of bag 2 is bag 1, that gives us:
50-3x = 1/2(50-x)
-> 50-3x = 25-x/2
Now lets isolate x and solve:
25 = 5x/2
-> 50 = 5x
-> x = 10
So plug x bag in for the original equations:
Bag 1: 50-3x = 50-3(10) = 20
Bag 2: 50-x = 50-10 = 40
Cone's volume is
where S - surface area, h - height
Surface area =
r = 18/2=9
h= 14
π = 3.14
