Answer:

(-1,2)

Step-by-step explanation:

To find the solution, we need to substitute in the points into the equation

5x-2y = -9

(1,-3)

5(1) -2(-3) = -9

5 +6=-9

11 =-9

This is not true so this is not a solution

5x-2y = -9

(2,-4)

5(2) -2(-4) = -9

10 +8 = -9

18 =-9

This is not true so this is not a solution

5x-2y = -9

(-1,2)

5(-1) -2(2) = -9

-5 -4 = -9

-9=-9

This is true so this is a solution

5x-2y = -9

(-2,5)

5(-2) -2(5) = -9

-10-10 = -9

-20=-9

This is not true so this is not a solution

Write the equation of the line that passes through the point (6, -2) and is perpendicular to the line

jolli1 [7]

Answer:

y = - 3x + 16

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = $\frac{1}{3}$ x + 8 ← is in slope- intercept form

with slope m = $\frac{1}{3}$

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{\frac{1}{3} }$ = - 3, so

y = - 3x + c ← is the partial equation of the perpendicular line

To find c substitute (6, - 2) into the partial equation

- 2 = - 18 + c ⇒ c = - 2 + 18 = 16

y = - 3x + 16 ← equation of perpendicular line

Find the volume of the composite solid. Round your answer to the nearest tenth.

lakkis [162]

The "cylinder" has a diameter of 6, and therefore its radius is half that, or 3, thus

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=3\\
h=11
\end{cases}\implies V=\pi (3)^2(11)\implies V=99\pi$
