Two angles are complementary. Angle 1 has a measure of

larisa86 [58]

Answer:

x = 10

Step-by-step explanation:

3x + 14 + 4x + 6 = 90

7x + 20 = 90

90 - 20 = 70

70 / 7 = 10

x = 10

Find the point P along the directed line segment from point A(-8,-3) to point B(6,12) that divides the segment in the ratio 1 to

Angelina_Jolie [31]

Bearing in mind that, the ratio here is 1:7 form A to B, that matters, because, the AB segment gets split in 8 pieces, and AP takes 1 slice whilst PB takes 7 slices

$\bf \left. \qquad \right.\textit{internal division of a line segment}
\\\\\\
A(-8,-3)\qquad B(6,12)\qquad
ratio1=1\qquad ratio2=7\qquad 1:7
\\\\\\
\cfrac{AP}{PB} = \cfrac{1}{7}\implies \cfrac{A}{B} = \cfrac{1}{7}\implies 7\cdot A=1\cdot B
\\\\\\
7(-8,-3)=1(6,12)\\\\
-------------------------------\\\\$

$\bf { P=\left(\cfrac{\textit{sum of "x" values}}{ratio1+ratio2}\quad ,\quad \cfrac{\textit{sum of "y" values}}{ratio1+ratio2}\right)}\\\\
-------------------------------\\\\
P=\left(\cfrac{(7\cdot -8)+(1\cdot 6)}{1+7}\quad ,\quad \cfrac{(7\cdot -3)+(1\cdot 12)}{1+7}\right)$

What is the equation of a line perpendicular to y=-8 through the point (-2,1)

Semenov [28]

Answer:

y=1/8x+1.25

Step-by-step explanation:

Since it's perpendicular change the slope to the opposite

You have the slope so plug it into the equation y-y1=m(x-x1)

y-(1)=(1/8)(x--2)
