Answer:
y = 
x + 8
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 )
rearrange 2x + 3y = 9 into this form
subtract 2x from both sides
3y = - 2x + 9 ( divide all terms by 3 )
y = - 
x + 3 ← in slope-intercept form
with slope m = -
given a line with slope m then the slope of a line perpendicular to it is
= - 
= -
= , hence
y = x + c ← is the partial equation
to find c substitute (- 2, 5) into the partial equation
5 = - 3 + c ⇒ c = 5 + 3 = 8
y = x + 8 ← equation of perpendicular line
To solve for m;
39 = 3m -12
39+12 = 3m -12 + 12 (add 12 to both sides)
51 = 3m
51 ÷ 3 = m
17 =m
m =17

Answer:
39
Step-by-step explanation:
The angles are equal. This means that the triangle is equilateral and all the sides are equal to each other.
Set any two sides equal to each other.
2x - 3 = x + 5
x - 3 = 5
x = 8
Now substitute this x value into all the sides and add the numbers up.
2(8) - 3 = 16 - 3 = 13
So we know all 3 sides equal 13.
13 * 3 = 39
