Im guessing that by making 10 it will speed up the addition process so it should be 
B since (6+4) = 10 then +5 =15

Complete the equation of the line through (-6, -5) and (-4, -4). Use exact numbers
77julia77 [94]


In general the equation through (a,b) and (c,d) is


(y-b)(c-a)=(x-a)(d-b)


Can you see that this is a line and that both (a,b) and (c,d) are on it?


Here we're given (a,b)=(-6,-5) and (c,d)=(-4,-4)


(y- -5)(-4 - -6) = (x - -6)(-4 - 5)


2(y+5)=x+6


2y + 10 = x + 6


x - 2y  = 4


y = \frac 1 2 x - 2


Either of the last two are fine answers.

Given circle E with diameter CD and radius EA. AB is tangent to Eat A.
faust18 [17]

The hypotenuse is equal to the square of the other two sides. The length of AC from the diagram is 21.9feet

<h3>Application of pythagoras theorem</h3>

The theorem states that the square of the hypotenuse is equal to the square of the other two sides

Given the following

Hypotenuse = 26 feet = CD
Base side = AD = 14ft

Required

Length AC

Use the theorem

26^2 = 14^2 + AC^2

AC^2 =  676 - 196
AC^2 = 480
AC = 21.9feet

Hence the length of AC from the diagram is 21.9feet
