Hey there! :)
Answer:
C. BC = 39 units.
Step-by-step explanation:
Use the Pythagorean theorem to solve for BC. Let BC = c, AB = a, and AC = b.
c² = a² + b²
c² = 15² + 36²
Square and simplify:
c² = 225 + 1296
c² = 1521
c = √1521
c = 39 units.
Therefore:
BC = 39 units.
Answer:
m = -0.8
Step-by-step explanation:
Use slope formula: (y2 - y1) / (x2 - x1)
Apply formula: ( 8 ) / (-10)
Simplify: -4 / 5

Answer:
(4x3)+(5x3)=12+15=27
Step-by-step explanation:
You can multiple both by any number as long as it adds to nine. 4 plus 5=9.
You can also do 3+6=9, or 8+1=9
25.12 ft would be the answer
Answer:
B
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 )
Given
4x + 5y = - 45 ( subtract 4x from both sides )
5y = - 4x - 45 ( divide terms by 5 )
y = - 
x - 9 ← in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= 
, then
y = x + c ← is the partial equation
To find c substitute (- 4, - 11 ) into the partial equation
- 11 = - 5 + c ⇒ c = - 11 + 5 = - 6
y = x - 6 → B
