Write an equation of the line through the given point (-3, -6) with the given slope m = 3. Write the equation in slope-intercept

nlexa [21]

So we know that the slope intercept form is y=mx+b

so the formula is y=3*-3+-6

Answer:

$\large\boxed{(x-2)^2+(y-1)^2=34}$

Step-by-step explanation:

The equation of a circle in standard form:

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

(h, k) - center

r - radius

We have the endpoints of the diameter: (-1, 6) and (5, -4).

Midpoint of diameter is a center of a circle.

The formula of a midpoint:

$\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)$

Substitute:

$h=\dfrac{-1+5}{2}=\dfrac{4}{2}=2\\\\k=\dfrac{6+(-4)}{2}=\dfrac{2}{2}=1$

The center is in (2, 1).

The radius length is equal to the distance between the center of the circle and the endpoint of the diameter.

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute the coordinates of the points (2, 1) and (5, -4):

$r=\sqrt{(5-2)^2+(-4-1)^2}=\sqrt{3^2+(-5)^2}=\sqrt{9+25}=\sqrt{34}$

Finally we have:

$(x-2)^2+(y-1)^2=(\sqrt{34})^2$

What is the image of A under the translation described by the translation rule (x, y)--->(x + 4, y - 10)?

Mademuasel [1]

Translation rule (x, y)--->(x + 4, y - 10)

Object A = (5, 6)

Apply rule:

(5, 6)---->(5 + 4, 6 - 10) = (9, -4)

Image A' = (9, -4)

Option 3: (9, -4) is the answer

The length of a rectangle is three times it’s width. The perimeter of the rectangle is 100 inches. What are the dimensions of th

BabaBlast [244]

Answer:

let the width be x inches

then the length would be 3x inches

perimeter of rectangle = p = 2(l+b)

100= 2(3x+x)

100= 2(4x)

100=8x

x=100/8

x=12.5 inches

thw width is 12.5 inches and length is 3*12.5=37.5 inches
