Ok, so since the graph of the line starts/ stops at the point $(0,0)$ we already know that y has to be equal to 0.

Now, because the y-axis is up and down, and the x-axis is left and right, your answer is $y\geq 0$ or y is less than or equal to 0 because the line is above (0,0) and also touches it

The graph gives no reason to expect that y=0 is excluded, so we conclude the range is ...

... y ≥ 0

Find an equation of the circle that has center (-4,3) and passes through (6,-4).

kumpel [21]

Answer:

$(x+4)^2+(y-3)^2=149$

Step-by-step explanation:

The equation of a circle is $(x-h)^2+(y-k)^2=r^2$ where $(h,k)$ is the center of the circle and $r$ is the radius of the circle.

Given that $(h,k)\rightarrow(-4,3)$ and it passes $(6,-4)$ , their distance between each other must the radius of the circle, so we can use the distance formula to find the radius:

$d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\\\\d=\sqrt{(-4-3)^2+(6-(-4))^2}\\\\d=\sqrt{(-7)^2+10^2}\\\\d=\sqrt{49+100}\\\\d=\sqrt{149}$

Therefore, if the length of the radius is $r=\sqrt{149}$ units, then $r^2=149$ , making the final equation of the circle $(x+4)^2+(y-3)^2=149$

The area of a rectangular patio is 400 square feet. The length of the patio is 9 feet more than its width. Find the length and w

oksano4ka [1.4K]

Answer:

Length: 16 feet

Width: 25 feet

Step-by-step explanation:

Alright so let's set up our system:

The area of a rectangular patio is 400 square feet.: L*W = 400

The length of the patio is 9 feet more than its width: L = W - 9

If you look here, all we need to do now is plug in L and solve.

(W - 9)W = 400

W^2-9W - 400 = 0

You can attempt to factor this in a number of ways. I recommend a factor tree, but however you do that is fine.

(W + 16)(W - 25) = 0

so we have two W values now, 25 and -16. Which one do we pick? We pick 25, because we cannot have a negative Width. That would literally break the universe.

So now we plug in 25 in our second equation to get L:

L = 25 - 9

L = 16

And now we have both our answers!
