Answer:
shortest side = 3 in
Step-by-step explanation:
Sum the 3 sides and equate to 13, that is
x - 5 + 6 + = 13, that is
x + 1 + = 13 ( subtract 1 from both sides )
x + = 12 ( multiply through by 2 to clear the fraction )
2x + x = 24
3x = 24 ( divide both sides by 3 )
x = 8
Thus
x - 5 = 8 - 5 = 3 and =
= 4 , then
The shortest side is x - 5 = 3 in
Answer:
y = - x -
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 )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (1, - 5) and (x₂, y₂ ) = (3, - 6)
m = = -
, then
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, - 5 ) , then
- 5 = - + c ⇒ c = - 5 +
= -
y = - x -
← equation of line
