Step-by-step explanation:

The solution is where both graph cross each other.

Is the solution, the point (x, y) that they gave you, the same point as where the two graph cross each other?

If yes then the solution is correct.

If no then the solution is wrong.

kotegsom [21]

First we compute the distance between the center and the given point which is exactly the radius

r =

$\sqrt{(x2 - x1) + (y2 - y1)} = \sqrt{9 - 3 + 11 - 7} = \sqrt{10}$

Now that we know the center and the radius, we can write the equation of a circle with given radius and center:

${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$

where (h,k) represent the coordinates of the center (3,7).

We substitute and obtain

${(x - 3)}^{2} + {(y - 7)}^{2} = { \sqrt{10} }^{2} \\ {(x - 3)}^{2} + {(y - 7)}^{2} = 10 \\ {x}^{2} - 6x + 9 + {y}^{2} - 14y + 49 = 10 \\ {x}^{2} + {y}^{2} - 6x - 14y + 48 = 0$

Elena gives the same amount of water to each of her 7 rose bushes. She has 5 gallons of water for the bushes.

Law Incorporation [45]

Answer:

5/7 gallons of water for each rose bush

Step-by-step explanation:

we know that

To find out the amount of water that Elena give to each rose bush, divide the total gallons of water by the number of rose bushes

$\frac{5}{7}\ \frac{gallons}{rose\ bush}$

therefore

5/7 gallons of water for each rose bush

Why does dividing by 100 shift each digit two places to the right?

alekssr [168]

The answer is D. If you divide 1000 by 100, it is 10. 10 is equal to 1/100 of its previous value of 1000.
