Answer:
slope - (-4/5)
y- intercept - (0,-2)
Step-by-step explanation:
Answer:
U=21
Step-by-step explanation:
What they are asking for is U. They tell you that the cost is 481 so the C is 481
481=20u+61
You minus 61 from 481 which is 420.
420=20u
Then you divide 20 from 420 and you will get 21.
It’s 6 my bad if I’m wrong
For this case we have that by definition, the general equation of the circle is given by:
Where,
- <em>(h, k): it is the center of the circle
</em>
- <em>r: radius of the circle
</em>
We then have the following equation:
Comparing values we have:
For the center of the circle
:
For the radius:
Then, the diameter is given by:
Answer:
Johnny is wrong:
The center of the circle is (11, -15)
Joyce is wrong:
The diameter of the circle is 24
1 ,3, 1
The first one is 1 the second is 3 and the last one is 1
