What is the slop-intercept of the line that passes through the points (7,-5) and (3,-9)?
bagirrra123 [75]

\bf (\stackrel{x_1}{7}~,~\stackrel{y_1}{-5})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{-9}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-9-(-5)}{3-7}\implies \cfrac{-9+5}{-4}\implies \cfrac{-4}{-4}\implies 1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-5)=1(x-7) \\\\\\ y+5=x-7\implies y=x-12

AB is tangent to circle O at B. Find the length of the radius, r, for AB = 5 and AO = 13.
alekssr [168]
ΔABO is a right triangle with AB⊥BO. The radius of the circle is BO. The Pythagorean theorem applies.
AO² = AB² + BO²
13² = 5² + r²
169 -25 = r²
r = √144 = 12

The radius (r) is 12.

What is h+20=35-4h simplified?
Contact [7]

Answer:

h=3

Step-by-step explanation:

h + 20 =35 -4h

h + 4h = 35 -20 ( so subtract 4h on both side and subtract 20 on both side )

5h=15

h = 15/5 ( so divide 5 on both side)

h=3
