What is an equation of the line that passes through the point (-3,-1) and is

Yuri [45]

Answer:

y = -2x - 7

Step-by-step explanation:

x - 2y = 6

-2y = -x + 6

Divide the whole equation by (-2)

$\frac{-2y}{-2}=\frac{-x}{-2}+\frac{6}{-2}\\\\y = \frac{1}{2}x - 3$

slope = 1/2

Slope of the line perpendicular to this line = -1/m = -1 ÷ (1/2)

$=(-1)*\frac{2}{1}\\\\= -2$

(-3, - 1)

y -y1 = m(x -x1)

y - [-1] = -2(x - [-3])

y + 1 = -2(x + 3)

y + 1= x* (-2) + 3*(-2)

y + 1 = -2x - 6

y = -2x - 6 - 1

y = -2x - 7

find the area of a circke with a radius of 9 mm. round to the nearest tenth. use 3.15 or 22/7 for Pi.

GREYUIT [131]

Answer:

254.3 mm^2

Step-by-step explanation:

Area of a circle: A = π*r^2

π (pi) = 3.14

r (radius) = 9 mm

Substitute 3.14 for pi and 9 for radius:

A = π*r^2

A = 3.14*9^2

A = 3.14*81

A = 254.34 mm^2

Round to the nearest tenth:

254.34 ==> 254.3

Therefore, our final answer is 254.3 mm^2

Hope this helps!
