Answer:

y+8 = 3(x-3)

Step-by-step explanation:

The point slope form of the equation for a line is

y-y1 = m(x-x1)

y- -8 = 3(x -3)

y+8 = 3(x-3)

4x+5y=-13;5x-2y=-8 solve elimination method <br> Step by step
goldfiish [28.3K]
4x + 5y = -13
2(4x + 5y) = 2(-13)
8x + 10y = -26 (equation 1)

5x - 2y = -8
5(5x - 2y) = 5(-8)
25x - 10y = -40 (equation 2)

equation 1 + equation 2,
(8x + 10y) + (25x - 10y) = (-26) + (-40)
8x + 10y + 25x - 10y = -26 + -40
33x = -66
x = -2

substitute x = -2 into equation 1,
8x + 10y = -26
8(-2) + 10y = -26
-16 + 10y = -26
10y = -10
y = -1

The values of x and y are -2 and -1 respectively.

Find the measure of arc DF in degrees, given that the shaded region has an area of 45.27 square centimeters. If necessary, round
marishachu [46]
\bf \textit{area of a sector of a circle}\\\\&#10;A=\cfrac{\theta \pi r^2}{360}\qquad &#10;\begin{cases}&#10;r=radius\\&#10;\theta =angle\ in\\&#10;\qquad degrees\\&#10;----------\\&#10;r=6\\&#10;A=45.27&#10;\end{cases}\implies 45.27=\cfrac{\theta\pi \cdot 6^2}{360}&#10;\\\\\\&#10;45.27\cdot 360=\theta \pi 6^2\implies \cfrac{45.27\cdot 360}{36\pi }=\theta&#10;\\\\\\&#10;144.09888547540\approx\theta \implies  144.10^o\approx\theta =\widehat{DF}&#10;\\\\\\&#10;\textit{now, that gives you the central angle, however}\qquad \theta =\widehat{DF}

bearing in mind that, arcs get their angle measurement from the central angle they're in.  Thus, the measure of that central angle, is the same measure in degrees of that arcDF.
